Answer:
- B) y = negative 4 x + three
Step-by-step explanation:
<u>Find the slope of the line that goes through (0, 8) and (2, 0):</u>
- m = (y₂ - y₁)/(x₂ - x₁)
- m = (0 - 8) / (2 - 0) = -8/2 = -4
Parallel lines have equal slopes.
<u>Looking at the choices we see only one of them has the slope of -4:</u>
The answer is (-21, 13) for The second endpoint.
Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.
(Kx + Lx)/2 = Mx
(Kx + 1)/2 = -10
Kx + 1 = -20
Kx = -21
And now we do the same thing for y values
(Ky + Ly)/2 = My
(Ky + 7)/2 = 10
Ky + 7 = 20
Ky = 13
This gives us the final point of (-21, 13)
Answer:
360 in ^3
Step-by-step explanation:
The volume is given by
V = l*w*h
= 8 * 5 * 9
= 360 in ^3
