Answer:
see the explanation
Step-by-step explanation:
Let
x ----> number of usage days
y ---> the total charge monthly in dollars
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 we have


substitute

we have the ordered pair (13,41)
For x=13 usage days


therefore
That means----> Total charge in one month for 13 days of use is $41
Y + 5x = 6
y + 5(-1) = 6
y + (-5) = 6
y - 5 = 6
y - 5 (+5) = 6 (+5)
y = 11
when x = - 1, y = 11
y + 5(0) = 6
y + 0 = 6
y + 0 (-0) = 6 (-0)
y = 6
when x = 0, y = 6
y + 5(1) = 6
y + 5 = 6
y + 5 (-5) = 6 (-5)
y = 1
when x = 1, y = 1
hope this helps
Answer:
$9.65
Step-by-step explanation:
Subtract the total amount from the change
50 - 1.75 = 48.25
Divide the resulting amount by the amount of pizzas
= 48.25/5
Simplify
= $9.65
C should be it, try it and see
