What is the slope of the line that passes through the points (-8, -3) and
Alchen [17]

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 8, - 3) and (x₂, y₂ ) = (- 12, - 3)

m = \frac{-3+3}{-12+8} = \frac{0}{-4} = 0

Find the inverse of h(x) = <img src="https://tex.z-dn.net/?f=%5Cfrac%7B2x%2B6%7D%7B5%7D" id="TexFormula1" title="\frac{2x+6}{5}"
Dima020 [189]

Answer:

The inverse of h(x) is \frac{5x-6}{2}

Step-by-step explanation:

* Lets explain how to make the inverse of a function

- To find the inverse of a function we switch x and y and then solve

  for new y

- You can make it with these steps

# write g(x) = y

# switch x and y

# solve for y

# write y as g^{-1}(x)

* Lets solve the problem

∵ h(x)=\frac{2x+6}{5}

# Step 1

∴ y=\frac{2x+6}{5}

# Step 2

∴ x=\frac{2y+6}{5}

# Step 3

∵ x=\frac{2y+6}{5}

- Multiply each side by 5

∴ 5x = 2y + 6

- Subtract 6 from both sides

∴ 5x - 6 = 2y

- Divide both sides by 2

∴ y=\frac{5x-6}{2}

# Step 4

∴ h^{-1}(x)=\frac{5x-6}{2}

Midpoint between 105 and 115
Black_prince [1.1K]

Answer:

110

Step-by-step explanation:

Subtract the greater value (115) by the smaller value (105) and this gives you the answer 10. So the distance between the two values is 10. Divide this by 2 to find the midpoint, and you get 5. You can either add 5 to the smaller value, or subtract 5 from the bigger value, either way you would get the answer of 110.

The town library is raising money by selling old books for $2 each.Which equation can be used to find the amount of money raised
alexgriva [62]
Y=2x
y is the amount of money made from the sold books
x is the number of books that are sold (it is x because you don't know how many will be sold, so you have to account for all possibilities)
2x is because every book is sold for 2 dollars, so that mean x is multiplied by 2 to get y
