I assume you meant -5x+20? If so,
-5(x-4) = 0 This is the answer
x = 4
Answer:
C= 22.65 + 0.65M
Step-by-step explanation:
The question isn't complete without values. Assuming the following is the complete question: A car rental company's standard charge includes an initial fee plus an additional fee for each mile driven. The standard charge S (in dollars) is given by the function S=16.95+0.40M, where M is the number of miles driven.
The company also offers an insurance option to insure the car against damage. The insurance charge (in dollars) is given by the function I=5.70+0.25M.
Let C be the total charge in dollars for a rental that includes insurance. Write an equation relating C to M. Simplify your answer as much as possible
SOLUTION
Solving the question based on the above complete question:
Standard charge = S = 16.95 + 0.40M
M= number of miles
Insurance charge = I = 5.70 + 0.25M
C = total charge in dollars
Relationship between C and M:
Total charge = standard charge + insurance charge
C = S + I
C = (16.95+ 0.40M)+ (5.70 + 0.25M)
C= 16.95+ 5.7 + 0.40M + 0.25M
Collect like terms by adding together
C= 22.65 + 0.65M
Answer:
y=x+4
Step-by-step explanation:
equation of line y=mx+c
where m= slope of line=1
put the coordinate (1,5) in equation of line
5=
+c
c=5-1=4
hence equation of line y=x+4
