X=-5
First add 4 to both sides
15+5x=2x
Then subtract 5 from both sides
15=-3x
Finally divide by -3 on both sides which gives you -5=x

What's the slope of the line passing through the points -1, 8 - 7, 3​
tatuchka [14]

Answer:

slope = 5/6

Step-by-step explanation:

Since you were given two points, you can use the point-slope formula to find the slope. The general equation looks like this:

y₁ - y₂ = m(x₁ - x₂)

In this formula, "m" represents the slope. To find the slope, plug the values from the two points into the equation. Make sure to put the values from the same point in the variable with the same number.

Point 1: (-1, 8)

Point 2: (-7, 3)

y₁ - y₂ = m(x₁ - x₂)                          <----- Original formula

8 - y₂ = m(-1 - x₂)                           <----- Plug in "x" and "y" values from Point 1

8 - 3 = m(-1 - (-7))                           <----- Plug in "x" and "y" values from Point 2

5 = m(-1 - (-7))                                <----- Simplify left side

5 = m(6)                                        <----- Simplify inside parentheses

5/6 = m                                       <----- Divide both sides by 6

What is -4R-2r+5 as a simpler exspression
enyata [817]
\sf-4R-2r+5 is already in simplest form.

But if you meant to say \sf-4r-2r+5, we would combine the first two terms.

Adding/subtracting like terms is the same as adding/subtracting whole numbers.

\sf-4-2=-6

Therefore:

\sf-4r-2r=-6r

Which gives us:

\boxed{\sf-6r+5}
