Answer:
B) h=63
Step-by-step explanation:
Multiply both sides by 9.
h/*9=9*7
Simplify

Answer:

Step-by-step explanation:
we know that
The quadratic function of the figure has a vertex at (2,-5) and the y-intercept is the point (0,3)
The equation of a vertical parabola in vertex form is equal to

where
(h,k) is the vertex
a is a coefficient
we have

substitute

with the y-intercept find out the value of a
For x=0,y=3




The equation is




Looking at the graph, the solution is the shaded area below the quadratic equation
so
the value of y must be less than or equal to the quadratic function

I don't know exactly what you want to know about this operation so I will put multiple answers.
