y =-3x + x + 9

Find y when x = 2

Substitute the value of x= 2 into the equation

y = -3(2) + 2 + 9

y = - 6 + 2 + 9

y = -4 + 9

y = 5

The answer is 5

Which expression is not equal to1/4 of 52
Art [367]
1/4 as a decimal is 0.25 (divide one by four). You can also multiply 1/4 by 52, but converting it into a decimal is typically easier.

"Of" typically means multiply, so multiply 52 * 0.25 to get the product 13.

For Option A., solve for 0.25 * 52, the final result should be 13.

For Option B., convert 4% into a decimal by dividing 4 over 100, you will get 0<span>.04, multiply 0.04 * 52 to get 2.08.
</span>
For Option C., divide 52 by 4, the quotient should be 13. 

For Option D., 52 over 4 is another way to write 52 divided by 4, therefore, the answer, once again, is 13. 

When comparing all the answers, you will notice all the answers are equal, except option B.

2.08 is not equal to 13

Therefore, your answer is <u>B. 4% of 52</u>

How do you equations like these? help a bro out pls
icang [17]

First solve for y

3x-y-2=1

subtract 3x from each side

-y-2=-3x+1

add 2 to both sides

-y=-3x+3

divide each side by -1

y=3x-3

To graph you could make a table:

x   y

0   -3

graph that.... point and use rise over run for slope 3/1 and graph.
