100 * pi = pi * r^2
Pi cancels on both sides of the equation
So... 100= r^2
= radius is 10
F(x)=(x+4)2−13 i think this is the simplified of the perfect trinomial
Lets make the graph of our systems of equations:
The blue line correspond to the equation x-y=3 and the red one correspond to 7x-y=-3. The lines intersect at point (-1,-4), then, the solution of the system is (-1,-4).
I think maybe about 5 times
Answer:
Place the f(x) expression 2x-3 into the x in the g(x) expression 4x+5, so it will be 4(2x-3)+5; you can expand it out if you want
