There are two parts of an equation (including this one), the coefficient, and the variable.
The coefficient is a known number, written as a digit, whereas the variable is an unknown number, written as a letter to signify an unknown number.
So, the coefficient in the first term (or part of the equation) is -2. The coefficient in the second term is 9, and the variable in this equation is x.
Change the signs on both sides of the equation 2x-3y-12=0
5x-11+8x-3 =90
13x-14=90
13x=104
X=8
Answer:
9, 18, 27, 36, 45, 54, 63, 72, 81, 90

Answer:
<u>(-9, -9)</u>
Step-by-step explanation:
Midpoint Formula :-
(x, y) = (x₁ + x₂ / 2, y₁ + y₂ / 2)
= (-7 + -11 / 2, -13 + -5 / 2)
=<u> (-9, -9)</u>
