7532 Question 1 of 7 The equation 4x – 45 = y is used to find your profit, y, in dollars from buying $45 of supplies and washing cars for $4 each. What does the x stand for?

x stands for the number of cars washed with the supplies.

Step-by-step explanation:

Given;

Profit equation; y = 4x - 45

Price of supplies = $45

Amount received per car wahed = $4

From the equation given, we can notice that the higher the value of x the higher the profit generated.

Since, for washing a car brings $4, 2 car is $8 and so on... So the value of x is the number of cars washed with the supplies.

x stands for the number of cars washed with the supplies.

For example, if we wash 15 cars. x = 15

y = 4(15) - 45 = 60 - 45

y = $15

The answer is "Square the number of the term, n"

Notice the pattern
1^2 = 1*1 = 1
2^2 = 2*2 = 4
3^2 = 3*3 = 9
4^2 = 4*4 = 16
5^2 = 5*5 = 25
6^2 = 6*6 = 36
the pattern goes on forever

In general, if n is any number then we have n^2 = n*n as the term
Ie, nth term is n^2

In our case, the next term is the 6th term with n = 6, so n^2 = 36
