n = 30....................
Answer:
Step-by-step explanation:
Each equation is in vertex form, so you can easily determine the number of real roots. The leading coefficient tells you whether the parabola opens upward (positive) or downward (negative).
y = a(x -h)^2 +k
has leading coefficient "a" and vertex (h, k).
__
<u>f(x) = 1/3(x +5)^2 +7</u>
vertex: (-5, 7), opens downward
The vertex is above the x-axis, so there are two real roots.
__
<u>f(x) = -5(x -3)^2</u>
vertex: (3, 0), opens downward
The vertex is on the x-axis, so there is one real root.
74.7 maybe maybe
as 9 goes up your percent goes up, you would want 12% to go up to 100% so for every 1 that 9 increase 12 increases by 12.
basically divide 100 by 12 then multiply whatever you get x9
im pretty sure thats my best guess
The solution for this question would be. x += 5 hope it helps, and im truly am sorry if its incorrect!
