Answer:
In Heather's solution to the problem, she wrote and solved an equation.
Her work is:
Step 1: 1.08(x +9.01 +0.98 +5.01) = 21.87
Solving like terms
1.08(x+15}=21.87
dividing both side by 1.08
we get
x+15=21.87/1.08
x+15=20.25
subtracting both side by 13.9198
x=20.25-15
x=5.25
According to correction
;
<u>Option 1st</u>
<u>yes,it is correct</u>
The point-slope form:
We have the points (-5, 15) and (20, 25). substitute:
Answer:
point-slope form: 
slope-intercept form: 
standard form: 
8x^2-50 is your answer hopes this helps
The answer should be x = 3
The answer is choice A.
The vertex of the parent function has been shifted 3 units to the left and 4 units up. This is represented by the function f(x) = (x-3)^2 + 4
Note how y = 1(x-3)^2 + 4 is in the form y = a(x-h)^2 + k
(h,k) = (3,4) is the vertex
