Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Total Amount made = $250
Amount charged = $70 per car
Tips earned = $50
Equation 1 to represent the above
(Amount charged per car × number of cars) + tips earned = total amount made
Let number of cars = c
Hence,
$70c + $50 = $250
Part B:
Total Amount made = $250
Amount charged = $75 per car
Tips earned = $35
Cost of supplies per car washed = $5
Equation 2:
(Amount charged per car × number of cars) + tips earned - (cost of supplies × number of cars) = total amount made
$75c + $35 - $5c = $250
$70c + $35 = $250
C) Equation 1 does not include the cost incurred in getting the car washed while equation 2 takes into account the cost incurred in washing a car which is then subtracted from the amount charged per car. Also the tips earned in equation 1 is $50 while equation has a tips fee of $35
Answer:
C.
There is no repeated x or y values
We know that a relation is a function, when each input of x value gives exactly one output of y-value.
In a function two or more x-coordinates can give same y-value, but one x-value cannot give two y-values.
We can see that in our given set each x-value corresponds to exactly one y-value, therefore, the given set represents a function.

Answer:
The correct answer is f(3) = -294
Step-by-step explanation:
To find f(3), we have to find f(1) and f(2)
It is given that,
f(0)=5 and f(n+1)=-4f(n)+2
<u>To find f(1)</u>
using given information,
f(1) = -4f(0) + 2 = -4*5 + 2 = -20 +2 = -18
<u>To find f(2)</u>
f(2) = -4f(1) + 2 = -4*-18 + 2 = 72 + 2 = 74
<u>To find f(3)</u>
f(3) =-4f(2) + 2 = -4*74 + 2 =-296 + 2 = -294
Therefore the value of f(3) = -294
