Variables - a quantity that may change, depends on the context of the math problem. Ex: x,y
Terms - a variable, or constant, that is multiplied by a variable or variables.
Ex: 5x + 2 + 3y <-- has 3 terms
Coefficient - the constant that multiplies the variable and is next to a variable, Ex: (5x) <-- coefficient is 5
Constants - A fixed value such as 5, 6, 7, etc
The monthly cost for 17 hundred of cubic feet is $52.13.
<h3>What is a
linear equation?</h3>
A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let y represent the bill paid for x HCF of water.
The slope is 1.45, hence m = 1.45.
The monthly cost for 13 HCF is $46.33, hence:
46.33 = 1.45(13) + b
b = 27.48
y = 1.45x + 27.48
For 17 HCF:
y = 1.45(17) + 27.48 = 52.13
The monthly cost for 17 hundred of cubic feet is $52.13.

Answer:
Let the midpoint be M(x,y).
7) x= (3+1)/2= 4/2= 2
y= (-9+5)/2= -4/2= -2
M(2,-2)
8) x= (5-6)/2= -1/2= -0.5
y= (-1-3)/2= -4/2= -2
M(-0.5,-2)
Answer:
D) direct variation
Step-by-step explanation:
Since y changes depending on x, it is direct variation.
