Okay, for this one I would use elimination:
8x+(-2y)-10
or
8x-2y=10
2x=4y
x=2y
8(2y)-2y=10
16y-2y=10
14y=10
y=5/7
x=10/7 or 1 3/7. Hope it help!

Step-by-step explanation:
For a dilation about the origin, you just take your scale factor and multiply it to both the points.
Answer:

Answer:
vertex = (- 2, - 36)
Step-by-step explanation:
Given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
f(x) = 5x² + 20x - 16 is in standard form
with a = 5, b = 20 and c = - 16
= -
= - 2
Substitute x = - 2 into f(x) for corresponding y- coordinate
f(- 2) = 5(- 2)² +20(- 2) - 16 = 20 - 40 - 16 = - 36
vertex = (- 2, - 36)
