Answer:
9.01 maybe my math might be wrong
Step-by-step explanation:
We know that this parabola intecepts the x-axis in 6 and -3. This means that is a vertical axis parabola. But also we know that our parabola passes through (1,10). Graphing these we conclude that is a concave down parabola
The general formula for this is:
To solve this we need to form a 3 equations system with our three points
We can solve for c in the first one
and replace in the second one and solve for b:
And replace c and b in the third equation:
Solve for a:
so b and c:
So:
F(x) = \sqrt(x)
g(x) = 2\sqrt(x)
(f-g)(x) = \sqrt(x) - 2\sqrt(x)
(f-g)(144) = \sqrt(144) - 2\sqrt(144)
(f-g)(144) = 12 - 24
(f-g)(144) = -12
Answer:
y = -75
Step-by-step explanation:
Simplify both sides of equation
1/5y = -15
multiply both side by 5
1/5y * 5 = -15 * 5
y = -75
