Answer:
4 movies, $20
Step-by-step explanation:
Given data
Family Video
charges $10 for a monthly membership and
$2.50 per movie
let the number of movies be x
and the charge for x movies be y
y= 10+2.5x----------1
Babe's Movies
charges a $12
membership and $2 per
movie.
let the number of movies be x
and the charge for x movies be y
y= 12+2x----------2
equate 1 and 2
10+2.5x= 12+2x
collect like terms
12-10= 2.5x-2x
2= 0.5x
x= 2/0.5
x= 4 movies
put x= 4 in equation 1 or 2
y= 12+2x----------2
y= 12+2*4
y= 12+8
y= $20
The mode of this is 8,10, and 5
Your answer is, get the variable by itself.
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.

Answer:
Slope = 
4x + 3y = 23
Step-by-step explanation:
slope = 
The equation:
m is the slope
y - 5 = -4/3 (x - 2) Multiply both sides by 3
3y -15 = -4 (x - 2)
3y - 15 = -4x + 8
3y + 4x = 8 + 15
3y + 4x = 23
4x + 3y = 23
