We know that
<span>the vertex form of the equation is
y=a(x-h)</span>²+k
we have
y = 7x² + 14x +4
y=7(x² + 2x) +4
y=7(x² + 2x+1-1) +4
y=7(x² + 2x+1) +4-7
y=7(x+1)²-3
the answer is
y=7(x+1)²-3
To compare fractions with like numerator and different denominators, draw out the numerator and denominators to figure it out. So if you were to figure out 6/10 and 6/17, draw out the denominators and shade in how many of the numerators. Keep in mind to make sure you shade in the same area on the other fraction or else you will get confused.
Answer:
Simplifying
an = 8n + -7
Reorder the terms:
an = -7 + 8n
Solving
an = -7 + 8n
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Divide each side by 'n'.
a = -7n-1 + 8
Simplifying
a = -7n-1 + 8
Reorder the terms:
a = 8 + -7n-1
Answer:
A and c
