What is the slope of the line that passes through the points (-3, -9)(−3,−9) and (22, -4) ?(22,−4)? Write your answer in simples
bezimeni [28]

Answer:

1/5

Step-by-step explanation:

Equation: \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

Points: (-3, -9) and (22, -4)

y_{2} is the second y point that shows up on the question, basically go by order. So it's -4

y_{1} is -9, because again, in order of which coordinates pop-up first in the question

x_{2} is 22, x_{1} is -3

Now input into the equation, to make it easier we'll split the fraction into 2 equations:

\frac{y_{2} - y_{1}}{x_{2} - x_{1}} = y_{2} - y_{1} and x_{2} - x_{1}, we'll put them back in a fraction later

y_{2} - y_{1} = -4 - (-9) = -4 + 9 = 5

x_{2} - x_{1} = 22 - (-3) = 22 + 3 = 25

now put it in the fraction, remember y on top x on the bottom:

5/25, simplify, 1/5

Write a variable expression for the amount of your budget after b books
wel
Because if let's say you have 400$ for the year, and each book cost 10$. So it would be written as 400-10b since the quantity of books must be multiplied times their cost to calculate whether you are within or outside the budget.

At the park there a pool shaped like a circle. A - shaped path goes around the pool. Its inner diameter is 18 yd and its outer d
Hoochie [10]

Answer:

46 gallons

Explanation:

First, we need to calculate the area of the path. This area can be calculated as the difference between the area of the outer circle and the area of the inner circle. The area of a circle is equal to

A=\pi r^2

Where r is the radius. For the outer circle, the diameter is 28 yd, so the radius is equal to

radius = diameter/2

radius = 28 yd/2

radius = 14 yd

Then, the area of the outer circle is

\begin{gathered} A=(3.14)(14\text{ yd\rparen}^2 \\ \text{ A = \lparen3.14\rparen\lparen196 yd}^2) \\ A=615.44\text{ yd}^2 \end{gathered}

In the same way, the radius of the inner circle is

radius = diameter/2

radius = 18 yd/2

radius = 9 yd

Then, the area is

\begin{gathered} A=(3.14)(9\text{ yd\rparen}^2 \\ A=(3.14)(81\text{ yd}^2) \\ A=254.34\text{ yd}^2 \end{gathered}

So, the area of the path is

Area path = 615.44 yd² - 254.34 yd²

Area path = 361.1 yd²

Now, we know that one gallon can cover 8 yd², so we can calculate the number of gallons as

361.1\text{ yd}^2\times\frac{1\text{ gallon}}{8\text{ yd}^2}=45.14\text{ gallons}

Therefore, the number of gallons is 46 because we need to round the result to a whole number.
