Answer:
18
Step-by-step explanation:
13 + (⅔)t = 16 + (½)t
(⅔ - ½)t = 3
t/6 = 3
t = 18
Answer:
5. 8
6. 18
Step-by-step explanation:
5.
a(a^2 + a - 1) + 7 =
= a^3 + a^2 - a + 7
For a = -1,
= (-1)^3 + (-1)^2 - (-1) + 7
= -1 + 1 + 1 + 7
= 8
6.
2ab(a + b) - 3ab(a - b) =
= 2a^2b + 2ab^2 - 3a^2b + 3ab^2
= -a^2b + 5ab^2
For a = 1 and b = 2,
= -(1)^2(2) + 5(1)(2)^2
= -1(2) + 5(4)
= - 2 + 20
= 18

Answer: it’s half as much of the radius so the relationship is 4
Step-by-step explanation:
Answer:
c f(-1) = 1/4
Step-by-step explanation:
f(x) = x-1
-----------
x^2 -9
Let x=-1
f(-1) = -1-1
-----------
(-1)^2 -9
f(-1) = -2
-----------
1 -9
=-2/-8 = 1/4
