Answer:
a/3 -c =b
Step-by-step explanation:
a=3b+c divide 3 on both sides
a/3 =b+c subtract c on both sides
a/3-c = b
I used to overthink this all the time its easy i promise :)
Answer:
Step-by-step explanation:
The scatter plot is a plot of amount spent on entertainment(in dollars) against the number of hours worked. The equation of the line of best fit is given as
y = 0.6x + 21.82
This equation gives the predicted amount spent on entertainment while the table gives the exact amount spent on entertainment.
1) when the number of hours worked is 7.8,
The observed amount is $33.50
The predicted amount is y = 0.6 × 7.8 + 21.82 = $26.5
The residual is 33.5 - 26.5 = $7
2) when the number of hours worked is 10.2,
The observed amount is $21.5
Approximately 22
The predicted amount is y = 0.6 × 10.2 + 21.82 = $27.94
Approximately $28
The residual is 22 - 28 = $6
B because 18-6 = 12 and -2-x=-3x so then it will equal to -3x=12 divided by -3 and your answer is -4 so that means B
