Answer:
-1
f (x) = -3(x + 5)
Step-by-step explanation:
1) in f(x) = 1/3x-5, replace f(x)= with y= as follows: y = (1/3)x - 5
2) interchange x and y, obtaining: x = (1/3)y - 5
3) solve this result for y: (1/3)y = -x - 5, or -(x + 5). Next, multiply both sides by 3 to eliminate the fraction (1/3): y = -3(x + 5)
4) replace y with the symbol for "inverse of f(x);
-1
f (x) = -3(x + 5)
Answer:
26
Step-by-step explanation:
Sydney = x
Devaughn = 2x
x + 2x = 78
3x = 78
x = 78 / 3
x = 26

Answer:
The awnser is 16 times 2
equals 32
Step-by-step explanation:
The rule for this sequence is n + 3.
132 --> 135 is +3,
135 --> 138 is +3,
and 138 --> 141 is +3.
Let's use this rule until we find the 13th term.
132 (1)
135(2)
138(3)
141(4)
144(5)
147(6)
150(7)
153(8)
156(9)
159(10)
162(11)
165(12)
168(13)
168 is the 13th term in this sequence.
I hope this helps!
