Answer:
(6, -2)
Step-by-step explanation:
Correct question
At what point do the lines y = x - 8 and y = - 3x + 16 intersects?
Equating both expressions;
x - 8 = -3x+16
Collect like terms
x+3x = 16+8
4x = 24
x = 24/4
x = 6
Substitute x = 6 into any of the equation
Recall that y = x - 8
y = 6 - 8
y = -2
Hence the point (x, y) where they intersects is at (6, -2)
Cada caja contiene el mismo número de cuadernos. Si Mario transporta 120 cuadernos en total en una carretilla, ¿cuántos cuadernos habrá en 120 cajas iguales?
Answer:
Se almacena un cuaderno por caja, significando 120 cuadernos en 120 cajas iguales.
Step-by-step explanation:
A partir del enunciado, podemos calcular el número de cuadernos por caja al dividir el total de cuadernos en la carretilla por el número de cajas disponibles.
[tex]x = \frac{120\,cuadernos}{120\,cajas}[/tex]
[tex]x = 1\,\frac{cuadernos}{caja}[/tex]
Se almacena un cuaderno por caja, significando 120 cuadernos en 120 cajas iguales.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The value of x is 8.
The value of y is 3.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 7 is an equation.
We have,
11x - 20y = 28 ____(1)
3x + 4y = 36 _____(2)
Now,
Multiply 5 on (2).
11x - 20y = 28
15x + 20y = 180
26x = 208
This means,
x = 208/26
x = 8
Now,
11x - 20y = 28
11 x 8 - 20y = 28
88 - 20y = 28
88 - 28 = 20y
y = 60/20
y = 3
Thus,
The value of x is 8.
The value of y is 3.

If you would like to make $586 in 6 years, how much would you have to deposit in an account that pays simple interest of 3%?
Round all answers to 2 decimal places.
Answer:
$3255.56
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
P = 586 / ( 0.03 × 6 ) = 3255.5555555556
P = $ 3,255.56
The principal required to
accumulate interest of $ 586.00
on a rate of 3% per year for 6 years is $ 3,255.56.

Hello there !
Can I have some help with this question? Thank you !
Answer:
About 6 hours.
Step-by-step explanation:
The cylinder has a diameter of 10 meters and a depth of 1.4 meters.
First, we can find the volume of the cylinder, given by the formula:
[tex]V=\pi r^2h[/tex]
Where r is the radius and h is the height (or depth, in this case).
Since our diameter is 10, our radius is 5.
Therefore, the volume of the cylinder will be (using 3.14 as π):
[tex]V=(3.14)(5)^2(1.4)=109.9\text{ meters} ^3[/tex]
Since water is pumped at a rate of 18 cubic meters per hour, it will take then:
[tex]109.9/18=6.10\overline{5}\approx 6\text{ hours}[/tex]
So, it will take about 6 hours for the water to completely fill the pool.

Which triangle is similar to △ABC if sin(A) = One-fourth, cos(A) = StartFraction StartRoot 15 EndRoot Over 4 EndFraction, and tan(A) = StartFraction 1 Over StartRoot 15 EndRoot EndFraction?
Answer:
ΔXYZ
Step-by-step explanation:
Trigonometric identities are equations which are true for right angled triangles. They are:
sin(A) = opposite / hypotenuse, cos(A) = adjacent / hypotenuse, tan(A) = opposite / adjacent.
Given triangle ABC with ∠A with side BC opposite to the angle, ∠B with side AC opposite to the angle, ∠C with side AB opposite to the angle.
sin(A) = opposite / hypotenuse = BC / AC = 1/4
BC = 1, AC = 4
cos(A) = adjacent / hypotenuse = AB / AC = √15 / 4
AB = √15
tan(A) = opposite / adjacent = BC / AB = 1 / √15
Two triangles are said to be similar if the ratio of their corresponding sides are in the same proportion.
ΔXYZ and ΔABC are similar because the ratio of their corresponding sides are in the same proportion.
For adjacent side; XZ / AB = 6√15 / √15 = 6
For opposite side; YZ / BC = 6/1 = 6
For hypotenuse side; XY / AC = 24 / 4 = 6

D. ΔXYZ

Answer:0.75757575757
Answer:
Fraction Form
25/33
Decimal Form
0.75
Step-by-step explanation:
First, convert the mixed fraction into an improper fraction, so it would look like:
-5/3 / (-11/5)
Next, divide. Remember, when multiplying fractions all you do is flip the one in parantheses and make both of them positive, so it would look like:
5/3 x 5/11
Finally, multiply so you do the two top numbers which is 5 x 5= 25 and the two bottom numbers so 11 x 3 is 33. Then your final answer is 25/33

Answer:
slope=(2--10)/(-4-2)=12/-6=-2
The required slope of the line is -2.
Given that,
To find the slope of the line that contains (2, -10) and (-4, 2).
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The slope of any line is given as if two points are given,
m = [y₂ - y₁] / [x₂ - x₁]
the slope of the line that contains (2, -10) and (-4, 2)
m = [2 + 10 ] / -4 - 2
m = 12 / -6
m = -2
Thus, the required slope of the line is -2.

The function g(t) = -16t2 + vt + h represents the height of an object, g, in feet above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet.
A model rocket is launched off the ground at an initial velocity of 80 feet per second.
Write a function that can be used to describe the flight of the model rocket.
A. g(t) = -16t^2 + 80
B. g(t) = -16t^2 + 80t
C. g(t) = -16t^2 + t + 80
