1. Find the x- and y-intercepts for the line given by the equation 3x + 2y = 12
3x + 2(0) = 12
Simplify to 3x = 12
Divide by 3 to get
x=4
x-intercept is x = 4
3(0) + 2y = 12
Simplify to 2y = 12
Divide by 2 to get
y=6
y-intercept is y = 6.
Thus, the line 3
1. Solve each of the following equations for the unknown variable.
a) 15x + 40 = 8x - 9
Start by subtracting 40 from both sides of the equation
15x + 40 = 8x - 9
- 40 = 8x - 40
15x
= 8x 49
Next, Subtract 8x from both sides of the equation
15x
= 8x - 49
-8
