Correct option is C

Answer: x= -6 I'm not sure about this though.

Step-by-step explanation:

Answer:

-9 = 0.45m

Step-by-step explanation:

[tex]0.45m - 9 = 0.9m[/tex]

^ Subtract 0.45m from BOTH sides. so [tex]0.9m - 0.45m[/tex]... etcWhy? So that we can make the equation less complicated. Our goal is to isolate the variable m to be on one side of the "=" sign by itselfThat will equal to:

[tex]-9 = 0.45m[/tex]     <-- ANSWER

0.45m - 9 = 0.9m
-9 = 0.45m

If the next part asks you to solve for m, you’ll divide both sides of the equation by 0.45, and find m = -20

Midpoint is equidistant from the endpoints

Given points:

M(-2, 7), A(5, 3), B(x, y)

Use midpoint formula:

(x + 5)/2 = -2 ⇒ x + 5 = -4 ⇒ x = -9(y + 3)/2 = 7 ⇒ y + 3 = 14 ⇒ y = 11

Point B is (-9, 11)
