Hey! Hope that I can help.
Answer:
It is important so we don't make the equation untrue
Step-by-step explanation:
If you don't balance the equation the two sides of the equation will not equal each other and make the equation untrue
Answer:
$350
Step-by-step explanation:
This is because in order to pay fees equal to $350 per month when doing haircuts, she would have to do 25 haircuts which equal $350 since 14 x 25 or 14 * 25 is 350.
Substitution:
350 = 14x
/14 /14
25 = x
Answer:
The linear function is 
The reasonable domain is 
Step-by-step explanation:
Let
x ----> the time in hours
y ---> the distance in miles
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem
The slope is 
The y-intercept is 
substitute

<em>Find the domain for x</em>
For y=120 miles
Find the value of x
substitute the value of y in the linear equation and solve for x




therefore
The domain is the interval [0,2]
