(for this answer i'm gonna use 0 to make it easier 
firstly you have to reoder the terms like this : 18 + 3 (-13+9f)=0
then  you multiply -13 and 9f by 3 like this : 18 + (-13 x 3 + 9f x 3)=0 and it should be like this: 18 + (-39 + 27f)=0
Next you have to combine like terms which is: 18 + -39 and you will get -21 and you add it to 27f which is: -21 + 27f=0 and you have to solve for the variable f and move all the terms containing f to the left and all other terms to the right.

What value of R makes r/ -11 = (-3) true
marissa [1.9K]

Answer:

The value of r=33 which makes the equation true.

Step-by-step explanation:

Given the equation

\frac{r}{-11}=-3

We have to find the value of r for which the equation must be true.

solving the equation

\frac{r}{-11}=-3

Multiply both sides by -11

\frac{r\left(-11\right)}{-11}=\left(-3\right)\left(-11\right)

r=33

Therefore, the value of r=33 which makes the equation true.

<u>VERIFICATION:</u>

Putting r=33 in the equation

\frac{r}{-11}=-3

\frac{33}{-11}=-3

-3=-3              ∵ \frac{33}{-11}=-3

L.H.S = R.H.S

Therefore, the value of r=33 which makes the equation true.

If someone knows the answer please help
pickupchik [31]

The correct answer is D. D'(1, 5), E'(-1, 3), F'(-1, -4), G'(1, -2).

It's because of this: You need to calculate the distances, and they are in this case symmetric, so you look how far is from one side, and it will be the same on the other side. When you put it on graph, the coordinates are clear and the correct answer is D.
