Which equation models the statement shown? y varies directly with x and =25 y = 25 when =5 x = 5 .

The value of y is 125 when x=25.

Step-by-step explanation:

It is given that y varies directly as x. It means y is proportional to x.

Where k is constant of proportionality.

It is given that y=25 when x=5. Put x=5 and y=25 in the above equation to find the value of k.

Divide both sides by 5.

The value of k is 5.

The relation between x and y is defined by the equation

Put x=25 in the above equation.

Therefore the value of y is 125 when x=25.

answer:  

123455421

step-by-step explanation: easy

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
