Answer:
your correct answer is y=-1/5-3
Step-by-step explanation:
The linear equation of the line is y = -1/5x - 3 and y + 3 = -1/5(x - 0)
How to determine the line equation?The slope is given as:
m = -1/5
The y-intercept is given as:
c = -3
A linear equation in slope intercept form is represented as:
y = mx + c
So, we have:
y = -1/5x - 3
The equation in point slope form is calculated as follows:
y = -1/5x - 3
Add 3 to both sides
y + 3 = -1/5x
Express -1/5x as -1/5(x)
y + 3 = -1/5(x)
Subtract 0 from x
y + 3 = -1/5(x - 0)
Hence, the linear equation of the line is y = -1/5x - 3 and y + 3 = -1/5(x - 0)

Cesar comenta que su papa esta interesado en comprar un terreno o vivienda.En estos tiempos de cuarentena su padre ha aprendido a comunicarse mas por medio de las redes sociales y justamente,atraves de whappsap,un amigo le envio una imagen del terreno de una vivienda en venta. Su padre le mostro la imagen y quiere que le alyude a realizar diversos calculos.si los calculos son 40m+14m+a+20m+54m+20+a.¿cual es el area de la vivienda?
Answer:
El área de la casa es de 1,304 m²
Step-by-step explanation:
De las dimensiones dadas en línea, tenemos que el área del jardín = 640 m²
Las dimensiones del jardín son;
Longitud = 40 m.
Ancho = a m
Por lo tanto, 40 × a = 640
a = 640/40 = 16 m
La dimensión del compuesto es así;
Longitud = 40 + 14 = 54 m
Ancho = 20 + a = 20 + 16 = 36 m
El área del compuesto = Área de la casa + Área del jardín
El área del compuesto = Ancho del compuesto × Longitud del compuesto
El área del compuesto = 36 × 54 = 1,944 m²
∴ 1,944 m² = Área de la casa + Área del jardín
1,944 m² = Área de la casa + 640 m²
Área de la casa = 1,944 m² - 640 m² = 1,304 m²
El área de la casa = 1,304 m².

Leonardo wrote an equation that has an infinite number of solutions. One of the terms in Leonardo's equation is missing, as shown below. Negative (x minus 1) + 5 = 2 (x + 3) minus box Which could be the missing term that Leonardo put into the box? x 3x 1 5
Answer:
The missing term is 3x
Step-by-step explanation:
Given
-(x - 1) + 5 = 2(x + 3) - _
Required
Find _
For proper identification of the parameters, represent _ with Z
So, the equation becomes
-(x - 1) + 5 = 2(x + 3) - Z
Open bracket (start from the left hand side)
-x + 1 + 5 = 2(x + 3) - Z
-x + 1 + 5 = 2x + 6 - Z
Solve like terms
-x + 6 = 2x + 6 - Z
Subtract 6 from both sides
-x + 6 - 6 = 2x + 6 - 6 - Z
-x = 2x - Z
Subtract 2x from both sides
-x - 2x = 2x - 2x - Z
-3x = -Z
Multiply both sides by -1
-3x * -1 = -Z * -1
3x = Z
Reorder
Z = 3x
Hence, the missing term is 3x

Find the ordered pairs for the x- and y- intercpets of the equations 3x-2y=18 and select the appropriate option below
Answer:
ordered pairs for the
x-intercept : (6,0)
y- intercepts :(0,9)
Step-by-step explanation:
Given equation : 3x-2y=18
X- intercept on coordinate plane is point where the line intersect the x- axis.
The coordinate of point y is 0 for x-intercept.
Based on this let the coordinate of X- intercept be (x,0)
we will plug this value in equation 3x-2y=18, to find value of x and hence we will get x-intercept
3x-2y=18
3x -2*0 =18
=> 3x = 18
=> x = 18/3 = 6
Thus, coordinate of x-intercept is (6,0)
________________________________________________
Y- intercept on coordinate plane is point where the line intersect the y- axis.
The coordinate of point x is 0 for y-intercept.
Based on this let the coordinate of X- intercept be (0,y)
we will plug this value in equation 3x-2y=18, to find value of y and hence we will get y-intercept
3x-2y=18
3*0 -2y =18
=> 2y = 18
=> y = 18/2 = 9
Thus, coordinate of y-intercept is (0,9)
Wendy is creating a large soup based on a recipe. Her recipe calls for of a pint of milk, but she only has of a pint of milk, so she can only make a portion of her soup. Wendy can only make _____ of her recipe with the amount of milk that she has.
Answer:
She can only make 5/6 of her recipe with the amount of milk that she has.
Step-by-step explanation:
Some data of this problem is missing, the data missing is:
Her recipe calls for 3/4 of a pint of milk and she only has 5/8 of a pint of milk.
Now, to know what's the portion she can do with that amount we need to divide the amount of milk she has by the total amount she needs:
[tex]\frac{5}{8}[/tex] ÷[tex]\frac{3}{4}[/tex]
When we divide we turn the second fraction upside down (the numerator becomes the denominator and viceversa) and multiply, thus:
[tex]\frac{5}{8}[/tex]÷[tex]\frac{3}{4}=\frac{5}{8}[/tex]×[tex]\frac{4}{3} =\frac{20}{24}[/tex]
If we simplify this last expression we have:
[tex]\frac{20}{24}=\frac{10}{12} =\frac{5}{6}[/tex]
Thus, she can only make 5/6 of her recipe with the amount of milk that she has.
Note: In case the data missing is different, you can apply this same procedure with the fractions you have.
Find dy/dx of (3 - 2x)-1/2
Answer:
Step-by-step explanation:
To evaluate the derivative of this function you need the chain rule. The pattern I teach to my calculus students is to find
u =
u' =
f(u) =
f'(u) =
First pick your "u". u will be the inner function, the one inside the parenthesis.
u' will then be the derivative of u.
f(u) is the function in terms of u, and
f'(u) is the derivative of the function in terms of u.
The derivative then, finally, will be u' * f'(u). Let's begin.
Our u, or the part of the function inside the parenthesis is 3 - 2x; hence,
u = 3 - 2x
The derivative, u', then is
u' = -2
f(u) is the function in terms of u, so
f(u) = [tex]u^{-\frac{1}{2}[/tex] and the derivative in terms of u is
f'(u) = [tex]-\frac{1}{2}u^{-\frac{3}{2}[/tex]
u' * f'(u) then is
[tex]-\frac{1}{2}u^{-\frac{3}{2}*(-2)[/tex] Simplify that by subbing back in for u and multiplying -2 by -1/2 to get
[tex]y'=(3-2x)^{-\frac{3}{2}[/tex]

and y, and solve for
Answer:
To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and [tex]f^{-1}(x)= \frac{ln\ x+4}{2}[/tex]
Step-by-step explanation:
Data provided in the question
f(x) = e^2x - 4
Now
to find the inverse let
So,
y = e^2x - 4
Now
Replace x and y
Therefore
x = e^2y - 4
Now compute the value of y
So,
x + 4 = e^2y
Now take ln on both sides:
The equation is
ln(x+4) = ln(e^2y)
ln(x+4) = 2y
y = ln(x+4) ÷ 2
[tex]f^{-1}(x)= \frac{ln\ x+4}{2}[/tex]
Therefore, To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and [tex]f^{-1}(x)= \frac{ln\ x+4}{2}[/tex]

Choose one of the theorems about chords of a circle and state it using your own words. Create a problem about chords that uses the theorem that you explained. Choose a problem that a classmate has posted, and explain how to solve it. Note: If you do not see any other responses, explain how to solve the problem that you posted. Please number your responses to the questions as they are shown (1, 2, and 3).
Answer:
Step-by-step explanation:
1. A given chord on a circle is perpendicular to a radius through its center, and it is at a distance less that the radius of the circle.
2. A circle of center O has a radius of 13 units. If a chord AB of 10 units is drawn at a distance, d, to the center of the circle, determine the value of d.
3. From question 2, the radius = 13 units, length of chord = 10 units and distance of chord to center of the circle is d.
A radius that meet the chord at center C, and divides it into two equal parts.
So that;
AC = CB = 5 units
Applying Pythagoras theorem to ΔOCB,
OC = d, CB = 5 units and OB = 13 units
[tex]13^{2}[/tex] = [tex]5^{2}[/tex] + [tex]d^{2}[/tex]
169 = 25 + [tex]d^{2}[/tex]
169 - 25 = [tex]d^{2}[/tex]
144 = [tex]d^{2}[/tex]
⇒ d = [tex]\sqrt{144}[/tex]
= 12 units
Therefore, the chord is at a distance of 12 units to the center of the circle.
A chord is a straight line joining 2 points on the circumference of a circle.
The line that connects any two points of the circumference of a circle is known as a chord.
Theorem: A radius or diameter that is perpendicular to a chord divides the chord into two equal parts and vice versa.
Converse: The perpendicular bisector of a chord passes through the center of a circle.
Problem: In the given figure the radius of the circle is 5 cms. what is the length of the chord?
Solution:
Given to us,
radius of the circle, r = 5 cms,
RA = 1 cm,
Radius, r = OA = OP = OQ = 5 cms.
Also, OR = OA - OR = 4 cms.
In ΔOPQ,
According to Pythagorus theorum,
OP² = OR² + RP²
5² = 4² + RP²
RP² = 25 -16 = 9
RP = 3,
We know,
A radius or diameter that is perpendicular to a chord divides the chord into two equal parts and vice versa.
A radius (OA) that is perpendicular to a chord divides the chord into two equal parts(RP = RQ).
Therefore, chord = RP + RQ = 3+3 = 6 cms.

On a nearby pond, black and white ducks are swimming in groups of 3. James wants to find the experimental probability of two white ducks and one black duck swimming together. Design a simulation using a coin flip and explain why it is the best choice for James.U Will get BRAINLIEST
Answer:
The answer is below
Step-by-step explanation:
Given that, there are only two available choices, which are a black or white duck, this can be represented using a coin: H→White duck, T→Black Duck
Hence, to represent a set of possible outcomes, the coin has to be tossed three times.
Thus, we assume that, at the minimum we have total number of Ducks = 3 Black + 3 White = 6 Ducks
Total Favorable Outcome = 2 White + 1 Black
Total Possible Outcome = Selecting 3 Ducks (2 White +1 Black) from 6 Ducks
Formula to Calculate Probability
= Total favourable outcome ÷ Total possible outcome
Use ,C(n,r)= n! / (n - r)! r!
Therefore, the Probability of two white ducks one black duck swimming together
= ³C² * ³C¹ ÷ 6C3 = 9/20
To use Simulation Coin Flip, we have the following:
H→White duck, T→Black Duck
HHH→Three White Ducks Swimming together
TTT→Three black ducks Swimming together
HHT→Two white duck and a Black Duck swimming together
HTH→Two white duck and a Black Duck swimming together
THH→Two white duck and a Black Duck swimming together
TTH→Two Black duck and a White Duck swimming together
THT→Two Black duck and a White Duck swimming together
HTT→Two Black duck and a White Duck swimming together
Finally, to find the probability, divide the observed desired outcomes by the total number of trials.
Answer:
There are only two choices, a black or white duck, so a coin is the best choice. To represent a set of possible outcomes, toss the coin three times. Repeat the experiment multiple times. To find the probability, divide the observed desired outcomes by the total number of trials.

A college student realized that he was spending too much money on fast food. For the remaining 5 months of the year his goal is to spend a mean of $50 a month towards fast food. How much can he spend in December, taking into consideration that in the other 4 months he spent $100, $25, $80, and $30, respectively? Round your answer to two decimal places, if necessary.
Answer:
The college student can spend $15.00 in December.
Step-by-step explanation:
This can be calculated as follows:
Let y represents the amount to spend in December.
The can now us the formula for calculating a mean is as follows:
Mean = Sum of montlhy spending / Number of months ...... (1)
From the question, we have:
Mean = $50
Sum of monthly spending = $100 + $25 + $80 + $30 + y = $235 + y
Number of months = 5
Substituting the values into equation (1) and solve for y, we have:
$50 = ($235 + y) / 5
$50 * 5 = $235 + y
$250 = $235 + y
$250 - $235 = y
$15.00 = y
Therefore, the college student can spend $15.00 in December.
