The function c(x)=18x-10 represents the cost in dollars. How many tickets can you buy?

Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.

So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 188 dollars.

The solution would still clear your concept though.

Please check the explanation.

Step-by-step explanation:

Given the function

The slope-intercept form of the line equation

We know that the slope-intercept form of the line equation

where m is the slope and b is the y-intercept

so

comparing with the slope-intercept form of the line equation

here:

and

'x' represents the number of tickets

Assuming the total cost i.e. c(x) = $188

In order to determine the value of x, set c(x) = 188

i.e.

188 = 18x -10

switch sides

188x - 10 = 170

add 10 to both sides

18x - 10 + 10 = 188 + 10

18x = 198

Divide 18 to both sides

18x/18 = 198/18

x =  11

Therefore, if you can buy x = 11 tickets if you pay  170 dollars.

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
