4 0

Answer:

We have

\frac{x^2-9}{x^2+2x-15}

\frac{\left(x+3\right)\left(x-3\right)}{x^2+2x-15}

\frac{\left(x+3\right)\left(x-3\right)}{\left(x-3\right)\left(x+5\right)}

\frac{x+3}{x+5}

∴The answer is D

What is the point of intersection when the system of equations below is graphed on the coordinate plane?
lora16 [44]

Answer:

<h2>not exist</h2>

Step-by-step explanation:

The coordinates of the intersection of the line are the solution of the system of equations.

\underline{+\left\{\begin{array}{ccc}x-y=1\\y-x=1\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad0=2\qquad\bold{FALSE}

The system of equations has no solution. Therefore, the lines are parallel (the intersection does not exist).

If f(x)= x*2 +3 and g(x) = 4x + 1, what is f(g(2))?
enot [183]

Answer:

f(g(2))=84

Step-by-step explanation:

Step one:

Given data

f(x)= x*2 +3

g(x) = 4x + 1

Step two

Let us find g(2) first then we proceed to find f(g(2))

g(2)=4(2) +1

g(2)=8+1

g(2)=9

Since g(2)=9

f(g(2))=x*2 +3

f(g(2))=9*2 +3

f(g(2))=81+3

f(g(2))=84
