Answer:
A. y = 7(x + 1)²-3
Step-by-step explanation:
Parabola:


Putting into vertex form, remember that:

In this question:
, to put into this format:

We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then
Vertex form:


So the correct answer is:
A. y = 7(x + 1)²-3
Answer:
x=7
Step-by-step explanation:
7x-7=4x+14
3x=21
x=7
Answer:
<em> n = 13 </em>
Step-by-step explanation:
=
+ (n - 1)d
= 3 + 7(n - 1) (for the first AP)
= 63 + 2(n - 1) ( for the second one)
3 + 7(n - 1) = 63 + 2(n - 1)
3 + 7n - 7 = 63 + 2n - 2
5n = 65
<em>n = 13</em>
They are compared by there size if thats what your asking.
