Riley uses the equation y = 10x to calculate the amount of money he earns after working x hours. The table below shows the amount of money Mandy earns after working different numbers of hours.
Hours Worked Amount Earned
9 $81
12 $108
15 $135
Which statement is true?
To determine which statement is true, we need to check if the given data corresponds to the equation y = 10x.
Let's plug in the hours worked and the corresponding amount earned from the table into the equation y = 10x and see if the values match:
For 9 hours worked:
y = 10x
y = 10(9)
y = 90
Since the amount earned for 9 hours worked is $81, which is not equal to 90, we can conclude that 9 does not satisfy the equation y = 10x.
For 12 hours worked:
y = 10x
y = 10(12)
y = 120
Since the amount earned for 12 hours worked is $108, which is not equal to 120, we can conclude that 12 does not satisfy the equation y = 10x.
For 15 hours worked:
y = 10x
y = 10(15)
y = 150
Since the amount earned for 15 hours worked is $135, which is not equal to 150, we can conclude that 15 does not satisfy the equation y = 10x.
Based on the given data, none of the amounts earned for the corresponding hours worked satisfy the equation y = 10x. Therefore, none of the statements would be true.
No statements. Cannot copy and paste here.
Sexist; Mandy's equation choices are all, y = 9x.
