Answer:
6.50x + 5 = 21.25 is the answer
Step-by-step explanation:
x=2.5
20 % = 225
1% = 225 / 20
100% = 225 * 100 / 20
= 1125 answer
X^2 -6x -8 is a parabola in ax^2 + bx + c form
The axis of symmetry is -b/2a = 3
The vertex is (3,f(3)) = (3,-17)
The x-intercept is f(x)= 0 where x=-1.123, 7.123
Graphing: it opens upwards
