For the equation to work, you have to have the same number on both sides of the equal sign
so to find ?, you can do:
13 - 2 = 12 - ? Simplify
11 = 12 - ? Subtract 12 on both sides
-1 = - ? Multiply -1 on both sides
1 = ?
The supplement of a 9 degree angle is 171 degrees.
Not sure what we are solving, please eloborate on what you need solved, for now I can’t answer
Answer:
slope is 9
Step-by-step explanation:
use the formula y=mx+b wherein m is the slope and b is the y-intercept
to solve for m, use formula (y2-y1)/(x2-x1):
=
(you add 5 and 9 together because negative + negative is positive)
126/14 = 9
