Answer:
4x²+7x+3
Step-by-step explanation:
4x² is by itself
5x+2x=7x
-3*2= -6 -6+9=3
when x = -9, y = 1
Here, we want to get the value of y when x = -9
To find this, we look at the point x= -9 on the x-axis
After getting this, we trace it to the graph
Looking at the graph, the graph crosses the x-axis at exactly this point
What this mean is that the value of y at that point is 1
Hence, for input -9, output is 1

Answer: True</h3>
Explanation:
The area of the circle with radius 10 is...
A = pi*r^2
A = pi*10^2
A = 100pi
The surface area of the sphere with radius 5 is...
SA = 4pi*r^2
SA = 4pi*5^2
SA = 100pi
Both results are the same, so the claim is true. We can think of surface area as the amount of wrapping paper needed to cover the sphere.
