Its D because supplementary means equal to 180 so 151+29 is 180 there its D
I just tried to help someone with the same problems. I hope this helps you
Answer:
$150
Step-by-step explanation:
The area of the lawn is 12m so 12 x 12.50 is 150. It would cost $150
Given: y = 2x^2 - 32x + 56
1) y = 2 [ x^2 - 16x] + 56
2) y = 2 [ (x - 8)^2 - 64 ] + 56
3) y = 2 (x - 8)^2 - 128 + 56
4) y = 2 (x - 8)^2 - 72 <----------- answer
Minimum = vertex = (h,k) = (8, - 72)
=> x-ccordinate of the minimum = 8 <-------- answer
Well, we can see that the y-intercept is (0, -4) which means that the line must be:
y=mx-4
And since only one answer has -4 as the y-intercept, y=x-4 is the answer :P
