Answer:

C. x\leq 3

Step-by-step explanation:

2(4+2x)\geq 5x+5

First expand the left hand side.

8+4x\geq 5x+5

Minus 4x and minus 5 on both sides.

8+4x-5-4x\geq 5x+5-5-4x

Simplifying it, you'll get

8-5\geq 5x-4x

Simplify it once again,

3\geq x which is also x\leq 3

<h3>Answer : (-2,11)</h3>

════════════════════

<h3>Known that</h3>

y = -2x² - 8x + 3

════════════════════

<h3>Way to do + explanation</h3>

#First, find the x coordinate first by using the formula of -b/2a

x = -b/2a = -(-8)/2(-2) = 8/-4 = -2

#After getting the x, find the y

y = -2(-2)² - 8(-2) + 3

y = -2×4 +16 + 3

y = -8 + 16 + 3

y = 11

So the vertex is

(-2,11)
