Can someone plz help me find the answer to 2x=4 y-16. and 2x-y=-7

telo118 [61]

Answer:

So, y = 2x + 7;

Then, 2x = 4( 2x + 7 ) - 16;

2x = 8x + 28 - 16;

2x = 8x + 12;

- 6x = 12;

x = - 2;

Then, y = 2· (-2) + 7;

y = - 4 + 7;

y = 3.

Find y intercept

y=5(0)²+20(0)-7
y=0-7
y=-7

Point(0,-7)

Find vertex

x coordinate

-b/2a
-20/10
-2

y coordinate

y=5(4)-40-7
y=-27

Vertex at (-2,-27)

Slope

m=(-27+7)/-2-0
m=-20/-2
m=10
