Answer:

-4

Step-by-step explanation:

So since x=5 and y= 1 the new expression would be 1(5-7) to the second power. Using pemdas, 5-7 is -2. -2 to the second power is -4. negative 4 times 1 is negative 4.

When y = 35,x = 2.5. If the value of y varies directly with x what is the value of y when the value of xis 3.25
leonid [27]

Answer:

The value of y would be 45.5

Step-by-step explanation:

To solve this problem, start with the base form of direct variation.

y = kx

Now we can use our original values to model the equation and find k.

35 = k(2.5)

14 = k

Now we can model the equation as:

y = 14x

Now to find y, when x = 3.25, simply put 3.25 into the equation.

y = 14(3.25)

y = 45.5
