Answer:
Domain = (-∞, -2) ∪ (-2, ∞).
Range = (-∞, 0) ∪ (0, ∞).
Step-by-step explanation:
t can't have the value -2 because that would make 1/(t + 2) = 1/0 which is undefined.
So the domain is All real values of t. except t = -2.
As t approaches infinity or negative infinity f(t) approaches zero, and as t approaches -2 from below or above f(t) approaches negative infinity or positive infinity.
Answer:
the answer is 4.5 and the sign is a negative. The sign is a negative bc you multiply 9 x -0.5, so a positive X a Negative = a Negative.
Answer:
y=4x+b

y = number of shoes isabelle has b = number of shoes leon has
Hi!
You're tripling three dimensions in this case; the length, the width, and the height. Since you're tripling all three of them, and not just one, you don't multiply the original by 3 just once, you multiply it by 3, three times, for all 3 dimensions.
You can use 3 ^ 3, or 3 * 3 * 3, to figure out how much you have to multiply the original by, since you're multiplying 3 by itself 3 times.
3 * 3 * 3 = 27
So you want to multiply the original value, in this case 200, by 27.
200 * 27 = 5,400 toothpicks
Hope this helped!
