Me plz and thank you

B. (-1, -3)

Step-by-step explanation:

Given M(1, -4) as midpoint of , and G(3, -5),

let

Rewrite the equation to find the coordinates of G

and

Solve for each:

Multiply both sides by 2

Subtract 3 from each side

Multiply both sides by 2

Add 5 to both sides

Coordinates of G is (-1, -3)

7

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
