Which equation is equivalent to the formula below?
2 answers:
Answer:
Choice D is correct.
Step-by-step explanation:
Given expression is :
y=a(x-h)²+k
we have to simplify it.
y=a(x-h)²+k
Adding -k to both sides of above equation,we get
y-k=a(x-h)²+k-k
y-k=a(x-h)²+0
y-k=a(x-h)²
Dividing by (x-h)² to both sides of above equation,we get
y-k/(x-h)²=a(x-h)²/(x-h)²
y-k/(x-h)²=a(1)
y-k/(x-h)²=a
a=y-k/(x-h)² which is the answer.
Option D is the correct answer :)

Answer:
y=5x-13
Step-by-step explanation:
y-y1=m(x-x1)
y-(-3)=5(x-2)
y+3=5(x-2)
y=5x-10-3
y=5x-13
