Answer:
To the left of the zero.
Step-by-step explanation:
Negative numbers are always on the left side of the zero on a number line.
21 x 9 = 9 x 21 is the commutative property.
Answer:
(0 - 5) + 5
Step-by-step explanation:
Picture the initial floor you were on in the beginning as ground level or "zero." you go <em>down</em> five floors- so youre going below zero, which would be a negative. However, because you are going back <em>up</em> those five floors, you are back on ground level. Thus, the answer would be zero.
Answer:
It's y = (5)(0.2)^x
_____________
Step-by-step explanation:
Exponential functions have a standard form of ab^x
Where a is the starting value, and b is the exponential growth or decay.
Because the numbers are getting smaller and smaller, it is a decay so b must be less than one.
We can eliminate the first choice because when x is 1, y is 1. If this where the equation we would get (5) (1/2) ^ 1 = 5 × 1/2 = 2.5 ≠ 1.
So the answer must be the second choice.
