Midpoint formula = (-9 + 6) / 2 = -3/2
Answer:
y=-3x+1
Step-by-step explanation:
plug in point into x and y, replace -4 as a +b(or any other variable to represent y intercept)
therefore,
7=-3(-2)+b
7=6+b
1=b
y=-3x+1
Answer:
A
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos X =
=
=
, then
∠ X =
(
) ≈ 44° ( to the nearest degree ) → A
Answer:
2,2
Step-by-step explanation:
f(x)=(x-2)^2+2
=2,2
Answer:
x = - 10
Step-by-step explanation:
Given
-
x = 8 ( multiply both sides by 5 to clear the fraction )
- 4x = 40 ( divide both sides by - 4 )
x = - 10
