1. k (j - 3) = m

Divide the k on both sides -> j - 3 = m/k

Add the 3 on both sides -> j = (m/k) +3

2. 3 (8 - x) + 12 = 102 - 6x

Subtract the 12 on both sides -> 3 (8 - x) = 90 - 6x

Add the 6x on both sides -> 3 (8 - x) + 6x = 90

Divide both sides by 3 -> 8 - x + 6x = 30

Combine like terms -> 8 +5x = 30

Subtract 8 from both sides -> 5x = 22

Divide both sides by 5 -> x = 22/5

3. Sorry, I can't remember exactly how to do the last one.

Solve the formula for C, thx if you answer!!

Alex_Xolod [135]

Making C the subject of the formula gives; C = R - P

<h3>How to find the subject of the formula?</h3>

The subject of a formula is the variable that is being worked out. It can be recognized as the letter on its own on one side of the equals sign. For example, in the formula for the area of a rectangle A = b h. Where A is the subject of the formula.

We are given the formula;

R - C = P

Now, to make C the subject of the formula, let us first add C to both sides to get;

R = P + C

Subtract P from both sides to get;

C = R - P

Thus, making C the subject of the formula gives; C = R - P

Answer:

Question 1: Answer would be A.

Question 2: Answer would be B.

Question 3: I cannot answer this one because an image is not provided. I do not have the image of the original triangle LMN. If you message me with a photo of this question, I will be able to answer.

Question 4: This answer may be wrong, but I believe that it would be A. I don't know how to calculate dilation transformations, but after graphing out all the points, I found that (6,4) would be the correct point because the distance between Point S and (6,4) is even and is able to be divided by two.

Question 5: Again, I cannot answer this one because an image is provided. Message me with a photo, I'll answer.

Question 6: Answer would be C.

Question 7: Again, I cannot answer this one because an image is provided. Message me with a photo, I'll answer.

Question 8: Answer would be C.

Step-by-step explanation:

Question 1 Explanation: Answer would be A because the quadrilateral was rotated 180 degrees and dilated to be larger.

Question 2 Explanation: Quadrant IV is on the bottom right, Quadrant I is on the top right. If a triangle were to be rotated from the origin (0,0), it would have to rotate 270 degrees in order to reach Quadrant I.

Question 3 Explanation:

Question 4 Explanation:

Question 5 Explanation:

Question 6 Explanation: Using a rotation calculator, I input the degree of rotation as -90.

Question 7 Explanation:

Question 8 Explanation: Using a rotation calculator, I input the degree of rotation as -180.
