Solve for n: 2m+7n=10 (also explain how you did it so i can follow the same steps for the rest of the questions)

n=(10-2m)/7

Step-by-step explanation:

2m+7n=10

subtract 2m from both sides

7n= 10-2m

divide by 7 on both sides

n=(10-2m)/7

(-14, -16), (-16, -16), and (-14, -20)

Step-by-step explanation:

First we see that k, the scale factor is -2, so it is enlargement. The triangles points are (7,8), (8,8), and (7,10). When you enlarge by a factor k you multiply every coordinate point by k, so the new triangles points would be (14,16), (16,16), and (14,20). Finally, the negative sign in k means that we rotate the triangle 180 degrees about the origin, and the rule for rotation of 180 degrees about the origin is (x, y) --> (-x, -y). So, the triangles points would be (-14, -16), (-16, -16), and (-14, -20).
