The flat fee that the store charges is $14 and the cost for 7 hours is $56
A linear equation is on 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 f for the total rental cost of a vacuum cleaner for x hours
Using the points (1, 20) and (3, 32) from the table:

The flat fee that the store charges is $14
The reasonable domain is 1 ≤ x ≤ 12
The cost for 7 hours is:
f(7) = 6(7) + 14 = 46

Answer:
Value of equation = 144
Step-by-step explanation:
Given:
5g + 7g + g(5 + 7) 
when g = 6
Find:
Value of equation
Computation:
5g + 7g + g(5 + 7) 
5g + 7g + g(12)
5(6) + 7(6) + (6)(12) 
30 + 42 + 72
Value of equation = 144
 
        
             
        
        
        
Answer:
x=12
Step-by-step explanation:
The two angles shown are complementary angles, so the add to 90 degrees
x+42 + 3x = 90
Combine like terms
4x+42 = 90
Subtract 42 from each side
4x+42-42 = 90-42
4x = 48
Divide by 4
4x/4 = 48/4
x = 12
 
        
             
        
        
        
Answer:
slope: 0 y-int: 6
Step-by-step explanation:
Horizontal lines ALWAYS have a slope of 0! Their y intercept is the y value they're always at, or the y value of the equation of their line. Looking at the graph, you can see that it's at 6.
