8. Which of the following is the minimum value of the function y = 1/2x^2 + 2x = + 8 ?

A. 6

B. 0

C. 8

D. 4

A. 6

Step-by-step explanation:

Use the formula  x = − b /2 a  to find the maximum and minimum.

( − 2 , 6 )

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
