Answer:
1/5
Step-by-step explanation:
Equation: 
Points: (-3, -9) and (22, -4)
is the second y point that shows up on the question, basically go by order. So it's -4
is -9, because again, in order of which coordinates pop-up first in the question
is 22, 
is -3
Now input into the equation, to make it easier we'll split the fraction into 2 equations:
= 
and 
, we'll put them back in a fraction later
= -4 - (-9) = -4 + 9 = 5
= 22 - (-3) = 22 + 3 = 25
now put it in the fraction, remember y on top x on the bottom:
5/25, simplify, 1/5
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.
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
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
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
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
Therefore, the number of gallons is 46 because we need to round the result to a whole number.
