Which expression is equivalent to 8x – 2y + x + 2? A) 4x
B) 83
(c) 6x – 2y
D 10x - 2y

D

Step-by-step explanation:

To find this out, we have to simplify the expression 8x-2y+x+2, so using PEMDAS, we can figure out that the first step here would be addition.

Combining like terms, we add (8x+x), which leaves the expression like this: 9x-2y+2.

So in conclusion, I have no idea what this would be since you can't simplify any more. My guess would be D, because that's closest, but you can't get rid of the 2, or the x or y terms without more information.

The functions have the same initial value

Step-by-step explanation:

As you can see, tour 2 starts at the point (0,35). This is the cost with no people. Tour 1 one the other hand starts at (1,45), not zero. So since the rate of change/slope is 10. Subtract 10 from 45 and you get 35. The same starting point as tour 2.
