Step-by-step explanation:
Because it is actually converting decimals to percentage.
Answer:
Step-by-step explanation:
y = (x^2 + 4x) + 2
Take 1/2 of the linear term 4/2 = 2 and square that result. 2^2 = 4.
Put it after 4x
y = (x^2 + 4x + 4) +2 Subtract what you put inside the brackets on the outside.
y = (x^2 + 4x + 4) + 2 - 4 Combine the right.
y = (x^2 + 4x + 4) - 2 Express the brackets as a square.
y = (x + 2)^2 - 2
That's your answer
a = 1
h = 2
k = -2
Answer:
Only the firsts and fourth choices (
and 
)
Step-by-step explanation:
Turn the equation into words:
"A number plus 9"
"Multiplied by 
"
"Is equals to -18"
Distribute to find the second equation:
