Answer:

681

Step-by-step explanation:

5x6=30

30x30=900

2x6=12-10=2

900+2=902

5x3=15

15x15=225

2x3=6

I have most of A like the x&y int and vertex I just need to know the equation in graphing form.

Serjik [45]

Step-by-step explanation:

a. $y = 2x^2 + 4x + 2\\y = (2x^2 +4x) +2\\y= 2(x^2+2x) + 2\\y = 2(x^2 +2x +1) + 2 - 2\\y = 2(x+1)^2 + 0\\(h,k) = (-1,0)$

b. $y = -x^2 +2x\\y = -(x^2-2x)\\y = -(x^2-2x+1)+1 \\y = -(x-1)^2+1\\(h,k) = (1,1)$

Then, the inequality is:
490x + 700 y ≤ 4000

The correct answer is the second option.
