Answer:
(b) a trapezoid
Step-by-step explanation:
A graph of the points reveals one pair of parallel sides: a trapezoid.
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.
Answer:
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:
- rate of change = 18
- c(x) or y represents the cost
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.
