Answer:

Step-by-step explanation:
Slope-intercept form is y = mx + b.
You are given 8x + 3y = -9, so to convert this into slope-intercept form you would solve for y and rearrange the terms (if needed) to follow the format of mx + b.
Start by subtracting 8x from both sides of the equation.
3y = -9 - 8x
Divide both sides by 3 to isolate y.
y = -3 - 8/3x
Rearrange the terms so the "x" variable is first.
y = -8/3x - 3
In a rectangle, there are 2 sides of length and two sides of width
So the perimeter of a rectangle is 2 length+2 width
2(18+3)
=42cm
6/5 of a mile or a mile and 1/5 they are the same
Answer:
Angie=x
Susan = x+3
Rebecca = 3(x+3)
Total = 5x+12
If Angie has 4 then the total is 32
Step-by-step explanation:
Angie has x games
Susan has 3 more games than Angie has
Susan = x+3
Rebecca has 3 times more games than Susan
Rebecca = 3Susan
We know Susan has x+3 so replacing it in
Rebecca = 3 (x+3)
The total number of games is Angie + Susan + Rebecca
x + x+3 + 3(x+3)
Distributing the 3
x + x+3 + 3x+9
Combining like terms
5x+12
The total number of games is
5x+12
If Angie has 4 games, x=4
The total number of games is 5(x)+12
5*4+12
20+12
32
