18<-3(4x-2)
Answer
x [tex]\leq[/tex] -1
Step-by-step explanation:
Answer:
x < - 1
Step-by-step explanation:
Given
18 < - 3(4x - 2)
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
- 6 > 4x - 2 ( add 2 to both sides )
- 4 > 4x ( divide both sides by 4 )
- 1 > x , then
x < - 1
A line that includes the point (-10,-5) has a slope of -8. What is its equation in point-slope form?
Answer:
Step-by-step explanation:
y + 5 = -8(x + 10)
y + 5 = -8x - 80
y = -8x - 85
Answer:
[tex]y + 5 = -8 (x+10)[/tex]
Step-by-step explanation:
The point-slope form of an equation is represented by the formula [tex]y-y_1 = m (x-x_1)[/tex]. Substitute values for the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula to write the equation of the line in point-slope form.
[tex]m[/tex] represents the slope, so substitute -8 in its place. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects. Thus, use the x and y values of the point (-10, -5) for the formula. Substitute -10 for [tex]x_1[/tex] and -5 for [tex]y_1[/tex]. This gives the following equation and answer:
[tex]y-(-5) = -8(x-(-10)\\y + 5 = -8 (x+10)[/tex]
use the geometric mean theorems to find AC and BD. BA=20 BC=15
Step-by-step explanation:
first, you use the pythagorean theorem to find the missing side of the original and big triangle.
[tex]20 {}^{2} + 15 {}^{2} [/tex]
next, you simplify these into actual numbers
[tex]400 + 225[/tex]
after, you add these numbers together and find the square root.
[tex]\sqrt{625} = 25[/tex]
you have the answer for AC. next you need to find BD. of you line up BC with BD, BC would be longer, , so you know its shorter, but not by much, so I'd assume to guess like 13 for BD- that's just me- but I'm not sure how to exactly find it.
The requried Measure of the BD and AC in the given question is 17.32 and 25 respectively.
What is the geometric mean theorem?The geometric mean theorem for a right triangle states that the length of the altitude (height) to the hypotenuse of a right triangle is the geometric mean of the lengths of the two segments of the hypotenuse.
Here,
From the triangle, following the Geometric mean theorem,
BD = √[AB×BC]
BD = √[20×15]
BD = √17.32
Now,
Applying the Pythagorean theorem to find AC,
AC = √15² + 20²
AC = 25
Thus, the requried Measure of the BD AC in the given question is 17.32 and 25 respectively.

A 44-inch pendulum swings at an angle of 14°. Find the length of the arc to the nearest hundredth of an inch through which the tip of the pendulum swings.
Answer:
10.75 inches
Step-by-step explanation:
A 44-inch pendulum swings at an angle of 14°. Find the length of the arc to the nearest hundredth of an inch through which the tip of the pendulum swings.
The formula of the length of the arc subtended by pendulum is given as = (x/360)*2πr or (x/180)*πr
Where:-
x = angle subtended by pendulum which is = 14°
r = Length of the pendulum = 44 inch
Lenghth of arc = ?
By putting values
Length of the arc = (14/180 × π × 44
= 10.751228192 inches

1. En la granja del tío de Carlos se han acomodado 525 huevos en cartones pequeños y grandes a razón de 3 2 . Si en los cartones pequeños se acomodaron 15 huevos y en los grandes 30, ¿cuántos cartones pequeños y cuántos grandes se utilizaron? donde dice 3 tendria que ir como una fraccion 3 y abajo del 3 el 2
Answer:
Small cartons used , x = 15
Large cartons used , y = 10
Step-by-step explanation:
Given - 1. On Carlos's uncle's farm, 525 eggs have been accommodated in small and large cartons at a rate of 3/2
2. If 15 eggs were accommodated in the small cartons and 30 in the large cartons.
To find - How many small cartons and how many large cartons were used?
Solution -
Let
Small cartons used = x
Large cartons used = y
Now,
Given that,
Small and large cartons at a rate of 3/2
⇒[tex]\frac{x}{y} = \frac{3}{2}[/tex]
⇒x = [tex]\frac{3}{2} y[/tex] ............(1)
Now,
Given that,
Total eggs accommodated = 525
Also,
15 eggs were accommodated in the small cartons and 30 in the large cartons.
⇒15 x + 30 y = 525
Now,
put the value of x in the above equation, we get
15([tex]\frac{3}{2} y[/tex] ) + 30 y = 525
⇒[tex]\frac{45 + 60}{2} y = 525[/tex]
⇒[tex]\frac{105}{2} y = 525[/tex]
⇒y = [tex]525*\frac{2}{105}[/tex]
⇒y = 5(2) = 10
⇒y = 10
Now,
Put the value of y, we get
x = [tex]\frac{3}{2} y[/tex] = [tex]\frac{3}{2}(10)[/tex] = 3(5) = 15
∴ we get
x = 15
y = 10
So,
Small cartons used , x = 15
Large cartons used , y = 10

find the equation of a line with a slope 3 that includes the point (0,5)
A. y = 3x + 0
B. y = 3x + 5
C. y = 5x + 3
D. y = -5x - 3
please help
Answer:
B
Step-by-step explanation:
We want to find the equation of a line with a slope of 3 that includes the point (0, 5).
We can use the slope-intercept form, given by:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
Notice that the given point (0, 5) is already the y-intercept. So, b = 5.
By substitution, we acquire:
[tex]y=3x+5[/tex]
Hence, our answer is B.
Answer:
B: y=3x+5
Step-by-step explanation:

Answer:
m^2 = 35/9
Step-by-step explanation:
The line will be tangent to the ellipse where there is one point of intersection between the line and the ellipse. We can find that case by looking at the discriminant of the quadratic.
x^2 +9(mx +2)^2 = 1
x^2 +9(m^2x^2 +4mx +4) = 1
(9m^2 +1)x^2+36mx +35 = 0 . . . . subtract 1, collect terms
__
Then the discriminant is ...
(36m)^2 -4(9m^2 +1)(35)
We want it to be zero, so we have ...
1296m^2 -1260m^2 -140 = 0 . . . . eliminate parentheses
36m^2 = 140 . . . . . . . . . . . . . . . add 140
m^2 = 140/36 . . . . . . . . . . . . divide by 36
m^2 = 35/9
