What is the difference? -6-(11)
lisabon 2012 [21]

Answer: =-17

Step-by-step explanation:

 The first thing you must remember is the mulplication of signs. You know that:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-

You can observe that the number inside the parentheses is positive (+) and the sign that is outside the parentheses is negative (-), therefore, when you multiply these signs you get a negative sign (-). Then you get:

-6-(11)=-6-11

Now, you need to add these numbers. And the result obtained is:

=-17

What is the rate of change for 8+ y = 2x
dalvyx [7]
The rate of change is also known as the slope. To easily find the slope of a line, put the equation into slope intercept form by isolating y on one side.

8 + y = 2x
y = 2x - 8

By definition, the rate of change is 2.

For the animal shelter, Elena Nppurchased
Naddik [55]

Elena's total cost (C) is 5(9.98 + 24.99 + x)

Since each dog leashes cost $9.98, each bag of dog food cost $24.99 and each crate of egg cost $x, hence:

Total cost (C) = 5 * $9.98 + (5 * 24.99) + (5 * x)

C = 5(9.98 + 24.99 + x)

Therefore Elena's total cost (C) is 5(9.98 + 24.99 + x)
