General regression equation :
y = mx + c
Where
y = predicted variable
x = predictor / explanatory variable
m = slope or gradient
c = Intercept
The regression equation obtained ;
ŷ = -0.08522X + 157.7779
To one decimal place :
ŷ = -0.1X + 157.8
The slope = - 0.1
Intercept = 157.8

Answer:
5390 gallons of water was wasted by the city's residents last year.
Step-by-step explanation:
Let
denotes gallons of water wasted by the city's residents last year.
Gallons of water wasted by the city's residents this year = 2695 gallons
This is 50% less than last year.
Therefore,

gallons
So, 5390 gallons of water was wasted by the city's residents last year.
Marquis solutions are;
- The value of x is less than or equal to -9.2.
- Negative 9.2 is greater than or equal to x.
- The closed circle is at -9.6 that is everything to the left of the circle is shaded.
<h3>What is inequality?</h3>
Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as we will as is used to compare two statements.
Marquis used the steps below to find the solution to the inequality Negative 5.6 greater than or equal to x + 3.6 that can be written as

A. Then the value of x will be
- 5.6 ≥ x + 3.6
-5.6 - 3.6 ≥ x
-9.2 ≥ x
B. Negative 9.2 is greater than or equal to x.
C. The number line is shown. The closed circle is at -9.6 that is everything to the left of the circle is shaded.
