Answer:
35
Step-by-step explanation:
2x+1=71
71-1=70
70÷2=35
therefore x must be 35
F(3) is 3 since the equation of the line is f(x)=3
72=1,72,2,36,3,24,4,18,6,12,8,9
28=1,28,2,14,4,7
So,the answer is 4
Solve for x, which can be done by moving x to the other side.
2(x-5)^2+8
So, x = 5
The y value is the number at the end and we can see that it is positive 8.
y = 8
Write it out as a coordinate pair and you would get (5,8) or answer choice D
