Answer:
the slope is -1, rise over run and since the line goes down from left to right it is negative
Answer:
x = 20
Step-by-step explanation:
I'm no mathematician but...
- 4 = x / 20 - 5
If you move the five to the other side using addition you get:
1 = x / 20
Then multiply 20 on both sides
20 = x

Answer:
NOT the graph A and the graph B.
Step-by-step explanation:
y = mx + b
m - slope
b - y-integer
If m > 0 then the function is increasing.
if m < 0 then the function is decreasing.
We have y = -2x + 3
m = -2 < 0 the function is decreasing
b = 3 y-intercept = 3
The x-intercept: y = 0. Substitute
0 = -2x + 3 add 2x to both sides
2x = 3 divide both sides by 2
x = 1.5
Therefore your answer is C or D (look at the picture)
Answer:
Step-by-step explanation:
The Westside recreation center built a new swimming pool that measures 20 ft by 15 ft. The pool is rectangular. The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length + width)
Therefore, perimeter of the pool would be
2(20 + 15) = 70 ft
The formula for determining the area of a rectangle is expressed as
Area = length × width
Therefore, area of the pool would be
20 × 15 = 300 ft^2
The formula for determining the volume of a rectangle is expressed as
Volume = length × width × height
Given depth = 6 feet
Therefore, volume of the pool would be
20 × 15 × 6 = 1800 ft^3
