Answer:
15x-45+7
Step-by-step explanation:
You would add the 10x and the 5x im pretty sure that would simplify it
Answer:
when x is -2 = -11
when x is 0 = -3
when x is 5 = 17
Step-by-step explanation:
plug each number for x into the equation so
1. -2
-3 + 4(-2)
4 x -2 =-8
-8 - 3 = -11
2. 0
-3 + 4(0)
4 x 0 =0
-3+0 = -3
3. 5
-3 + 4(5)
4 x 5 = 20
-3 + 20 = 17
Answer:
Part 1)
Part 2)
Part 3)
Step-by-step explanation:
we know that
The equation of the line into slope intercept form is equal to
where
m is the slope
b is the y-coordinate of the y-intercept
Part 1) we have
Simplify
Divide by 20 both sides
isolate the variable y
Subtract x both sides
Divide by 4 both sides
------> equation of the line into slope intercept form
Part 2) we have
Simplify
Divide by 10 both sides
isolate the variable y
Subtract (3x-10) both sides
Divide by 5 both sides
------> equation of the line into slope intercept form
Part 3) we have
Simplify
Divide by 3 both sides
isolate the variable y
Subtract (x-10) both sides
Divide by -5 both sides
------> equation of the line into slope intercept form
