Complete the square to rewrite y = x2 + 8x + 3 in vertex form, and then identify
the minimum y-value of the function.
O
A. The minimum value is -13.
O
B. The minimum value is -19.
O
C. The minimum value is -4.
O
D. The minimum value is -2.

if x decreases by 4 then y increases by 10

step-by-step explanation:

1st part is 64,000,000

2nd part 500,000

step-by-step explanation:

answer: idk

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
