Ok, so here, we need to use the slope formula which is:
(y2 - y1)/(x2-x1)
y2 = 9
y1 = 5
x2 = x
x1 = 10
So:
(9-5)/(x-10) = -2
Now, we just solve for x,
9-5 = -2(x-10)
4 = -2x+20
2x = 16
x = 8
Answer:
The answer is D.
Step-by-step explanation:
85 = 10x+15
70 = 10x
x = 7
180-85 = 95 = z
<h2>true</h2>
I did it on my calculater and the answer came as 13
hope that helps :)
