emmainna [20.7K]

Answer:

y = 23x - 6

Step-by-step explanation:

The formula for line is y =  mx + b

m is the slope, so plug in 23

b is the y intercept, so plug in -6

So it would be y = 23x + (-6), which simpify into y = 23x - 6

-2(x-5)=6(2- 1/2x)<br><br> Please show your work. Distributive property, remove variable
schepotkina [342]

The solution of given equation is x=2

Further explanation:

In order to solve the given equation we have to isolate the variable x on one side of the equation. The process will involve distributive property and simplification.

Given:

-2(x-5)=6(2-\frac{1}{2}x)\\Apply\ distributive\ property\\-2x-2(-5)=(6)(2)-(6)(\frac{1}{2}x)\\-2x+10=12-\frac{6}{2}x\\-2x+10=12-3x\\-2x+3x=12-10\\x=2

The solution of given equation is x=2
