Four times a number added to twelve is divided by seven times a different number minus twenty-eight. Convert this to math symbols using x and y for the variables. *

Step-by-step explanation:

Four times a number (let's call this x) is added to twelve. In other words, this is:

Now, this entire thing is divided by seven times a different number (let's use y) minus twenty-eight. So:

Let's put it into a fraction to simplify. Remember that dividing something by something else is the same as putting it over fraction. Thus:

And we're done!

12 + 4x

7y - 28

Step-by-step explanation:

Here we have 4 times a number is added to 12. So let's say that number is "x". Now we have 4x plus the 12 to get 4x + 12 And that is divided by 7 times a different number minus 8.

So 7 times a different number "y" is the same as 7y and put in that minus 28 to get 7y - 28 and don't forget the dividing!

It'll end up being;

12 + 4x

7y - 28

Hope this helps and have a great day!

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

i think it is c, not positive though
