The missing coordinate r is 11.
Solution:
Given points are (–15, 1) and (–7, r).
Slope (m) = 
<u>To find the missing coordinate r:</u>
Slope formula:
Substitute the given values in the formula.
Do cross multiplication.
40 = 4r – 4
Add 4 on both side of the equation.
44 = 4r
Divide by 4 on both side of the equation.
11 = r
⇒ r = 11
Hence the missing coordinate r is 11.

Step-by-step explanation:
Absolute value is alwas positive
so all of them excet the 3rd one are false
|w|=0 has 1 solution
if the last one was |w|=1 then ther would be 2 solutions, -1 and 1
answer is |w|=0
Answer:
<h3>B. 4 × 8.5 = 34</h3>
Step-by-step explanation:
The formula for calculating the perimeter of the square patio is expressed as;
P = 4L
L is the length of each side of the square patio
Given
L = 8.5 feet
Required
Perimeter in feet of Rocio's patio
Substitute the given parameter into the formula;
Perimeter = 4 * 8.5
Perimeter = 34ft²
Option B is correct.
