Answer:
B. y = (x + 3)^2 - 17
Step-by-step explanation:
When Andy completes the square, he adds and subtracts the square of half the x-coefficient. That is, he adds and subtracts (6/2)² = 9:
... y = x² +6x +9 -8 -9
... y = (x² +6x +9) -17
... y = (x +3)² -17 . . . . . . . . matches selection B
1,000 ¥ / $8 = 125 ¥ per $1
650 ¥ / 125 ¥ = $5.20
The answer is A. $5.20
( x - 8 )² = 144 / √ (take the square root of both sides of equation )
x - 8 = 12
x = 20 feet
Answer: D) 20 feet by 20 feet
E are given with two functions: h(x) = x – 7 and g(x) = x2. In this problem, we are asked to determine the value of g(h(5)). first we get g(h(x)) which is equal to (x-7)2, when x is substituted by 5, then g(h(5)) = (5-7)^2 equal to 4
It would be 10 because if you round the 9 by the 7 you would make the 9 into a 10.
