Convert to vertex form:-
f(x) = 4(x^2 + 2x) + 7
= 4[(x + 1)^2 - 1] + 7
= 4(x + 1)^2 + 3
The axis will be the vertical line x = -1

ANSWER: Y=2x+1. The formula of ur answer would be in y=mx+b. Since it is parallel to 2x+3y=15, the m would have to be the same. Therefore m =2. Next we find b. We would plug in the points (-3,-5) in the formula y=mx+b to find B knowing m= 2 so -5=2(-3)+b. B=1.
Answer:
Her federal tax = 700 × <u>13</u>
100
= 7× 13
= 91
sales tax = 700 - 91
= 609
= 609 × <u>6</u>
100
= 36.54
home pay = 700 -(91+36.54)
= 572. 46
Her federal tax = X × <u>13</u>
100
= X× 13
= 13X
sales tax = X - 13X
=
=(X - 13X) × <u>6</u>
100
=
home pay = X -(13X + ( X - 13X) )
I think this is the answer for your question.
