since the scale is by 2, and P is in between -6 and -8 so the answer is -7
B. -3 and 5
constants are the numbers without variables (the letters) and coefficients are the numbers with variables
Elevator 1 is 12 ft above ground level...and elevator 2 is 15 ft below ground level
Which number type? I'd go with Whole numbers or integers, since the steps are just whole values one step after the next.
well, an appropriate domain, namely the inputs, well, He's on the 5th step, there are 15 steps, so he's really 10 steps away from the top of the ladder, and going down N being negative, he's -5 steps from the ground.
{ N | N ∈ ℤ , -5 ⩽ N ⩽ 10 }
