C= 20-0.75x
c= 20-0.75(9)
c= 20-6.75
c= 13.25
Here c is the amount of change and x is the number of books bought.
The customer's change will be $13.25
Answer:
y = - 6x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - 6, hence
y = - 6x + c ← is the partial equation
To find c substitute (- 1, 7) into the partial equation
7 = 6 + c ⇒ c = 7 - 6 = 1
y = - 6x + 1 ← equation of line
Answer:
Im assuming you meant 43 because if you did x=5
Step-by-step explanation:
8 times 5 is 40 and ifyou add 3 it equals 43
Answer: (13,-7)
Step-by-step explanation:
By using the formula 
is the coordinates of the midpoint.
For finding the midpoint X variable do:
For finding the midpoint Y variable do:
(you can either keep the parenthesis or take them out. Either way, the answer is the same.
Considering coordinate numbers follow the format: (x,y), you'll simply just substitute the numbers found above into their respective places.
x: 13
y: -7
(13,-7).
