Answer:
45%
Step-by-step explanation:
Simply divide your partial amount (18 in this case) by your total (40), and you then multiply your answer from 18/40= .45 by 100, and you get 45. This is 45%
I’m pretty sure there are infinite solutions as the system of equations are equivalent to each other.
Rewrite the equation in term of x and y . F(x) = x-2)^2-4
Use the vertex form y=a (x-h)^2 +k to determine the values of a,h and k. A=1
H=2 k=-4 find the vertex 2,-4
The first one is a and the second one is b
