How many solutions is this 2x+8=-2x+8

Step-by-step explanation:

4x + 8 = 8

4x = 0

x = 0

onw

One solution x=0

Step-by-step explanation:

2x+8=-2x+8

Add 2x to each side

2x+2x+8=-2x+2x+8

4x+8=8

Subtract 8 from each side

4x+8-8=8-8

4x = 0

x=0

There is one solution

x=0

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
