Answer:
D - x = 19 x = -17
Step-by-step explanation:
Factor the equation to make the problem easier - you should have this:
(x - 18) (x + 18) = 1
Set each binomial to 1:
x - 18 = 1
x + 18 = 1
This should give you x = 19 and x = -17
Yes, it is a function, because no x value is repeated.
Answer:
84
Step-by-step explanation:
13 < 2t + 3 < 27
13<2t+3 2t+3<27
13-3<2t 2t<27-3
10<2t 2t<24
10/2<t t<24/2
5<t t<12
5 < t < 12
