Step-by-step explanation:
Answer:
a. f(x)=25+0.02x
b. 0 miles
Explanation:
The charges per week to rent a car =$25
There is an additional cost of $0.02 per mile.
Let the number of miles driven during the week = x
(a)The weekly cost, f o rent a car will be:
(b) If the weekly cost to rent the car was $25
f(x)=25
Substitution into f(x) derived above gives:
If the weekly cost was $25, the car was driven for 0 miles (was not driven at all).
Answer:X1=1+-1+i(2)^1/2
x2=-1-i(2)^1/2
Step-by-step explanation
y=y
-2x+1=-x^2+4
x^2+4+2x-1=0
x^2+2x+3=0
Use
Ax^2+Bx+C=0
X1,X2=[-B+(B^2-4*A*C)^1/2]/2*A
A=1
B=2
C=3
x=[-2+/-(2*2-12)^1/2]/2
x=[-2+/-(-8`)^1/2]/2
x=[-2+/-2i(2)^1/2]/2
x1=-1+i(2)^1/2
x2=-1-i(2)^1/2
