Answer:
Multiply c and 8
Multiply c and 1
The c just gets copied along.
The answer is c
c
8*c evaluates to 8c
Because of the minus sign
8c becomes - 8c
The answer is -8c
Multiply c and 8
Multiply c and 1
The c just gets copied along.
The answer is c
c
8*c evaluates to 8c
-8*c+8*c evaluates to 0c
-8*c+8*c-12 evaluates to -12
The final answer is
-12

Answer:
5/6x + 3 = y
Step-by-step explanation:
The slope intercept form is:
mx + b = y
The slope is 5/6.
The y intercept is 3.
A percentage is an amount out of 100. So .45% is 0.45/100. For me, it's easiest to just multiply the numerator and denominator by 100 to get rid of the decimal, giving me 45/10,000
hope this helped
Answer:
Non-proportional; the rate of change is $40/hour
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u>and the line passes through the origin</u>
Let
x -----> the number of hours
y ----> The total charge in dollars
The equation of the line in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have

substitute

This relationship is not proportional, because the line not passes through the origin
therefore
Non-proportional; the rate of change is $40/hour
