Plug this into the formula y2 - y1 / x2 - x1
-2 = x1, x2 = 2, y1 = -1, y2 = -3
-3 - (-1) / 2 - (-2)
-2 / 4
-1/2
The slope is -1/2.
Answer:
C and E and F
Step-by-step explanation:
Integers are basically whole numbers. For example, 6.5 is not an integer since it is not a whole number and it is between 6 and 7. Also fractions that cannot be simplified to whole numbers are not integers. Also integers can be negative.
Step 1
Find the area of one tile
we know that
the area of a square is
where b is the length side of the square
In this problem
Substitute
Step 2
Find the area of the floor
The area of a rectangle is equal to
where
L is the length of the rectangle
h is the width of the rectangle
In this problem
Substitute
Step 3
Find the number of tiles needed
by proportion
therefore
<u>the answer is</u>
A, 4 1/2, is the correct answer. I've taken AP Calculus before.
Answer:
10 minutes
Step-by-step explanation:
Let's call the Acme Company A and Beltone as B
Let m be the number of minutes
A = $21 + $0.05m
B = $15 + $0.11m
- A = B
- $21 + $0.05m = $15 + $0.11m
- $6 + $0.05m = $0.11m
- $6 = $0.06m
- 10 = m
It will take 10 minutes for both prices to be equal.
