Answer:

For first question answer is D.0.8

For second question answer is D.ΔMGR is similar to ΔNST.

Step-by-step explanation:

Here triangle FUN is dilated to get triangle PET

So, let's take F and P.

F(-2,4) and P(-1.6, 3.2)

Let's find the scale factor by dividing the coordinates.

Scale factor =\frac{-1.6}{-2} =0.8

Using y coordinates of the same points

Scale factor =\frac{3.2}{4} =0.8

So, scale factor is 0.8

Now, for the second problem

<G= <S

<R= <T

<M=<N

So, the corresponding angles are congruent when two triangles similar.

So, we can say ΔMGR is similar to ΔNST.

What is an equation of the line that passes through the point (2, -6) and is parallel
fomenos

Answer: y=-6

Step-by-step explanation:

First convert the equation -2y= 8 into y intercept form by divide both sides by -2.

-2y = 8  

y= -4     Now that the line is in y intercept form we can now determine the slope.The slope is 0  so -4 in this case is the y intercept.

Remember lines that a parallel needs to have the same slope but different y-intercepts.

So if the slope of the line y=-4 is 0 then the slope of line that passes through the point (2,-6)  

So using the y intercept form formula which says that y=mx+b where m is the slope and b is the y-intercept, we could plot in the values for y and x and solve for b to write the equation.

y is -6 and x is 2

-6 = 0(2) + b

-6 = 0 + b

b= -6  

In this case the y intercept is -6 so since the slope is zero we will have the equation  y = -6

<h3>Answer: Choice D) </h3>

Work Shown:

(f+g)(x) = f(x)+g(x)\\\\(f+g)(x) = \frac{x-23}{x^2+9x-36}+\frac{1}{x+12}\\\\(f+g)(x) = \frac{x-23}{(x+12)(x-3)}+\frac{1(x-3)}{(x+12)(x-3)}\\\\(f+g)(x) = \frac{x-23+1(x-3)}{(x+12)(x-3)}\\\\(f+g)(x) = \frac{x-23+x-3}{x^2+9x-36}\\\\(f+g)(x) = \frac{2x-26}{x^2+9x-36}\\\\

We must require that x \ne -12 and x \ne 3 to avoid having 0 in the denominator. This is why choice D is the answer.
