Answer:

For 13: 13/30

Step-by-step explanation:

First simplify!

9x - 25 + 21x - 35 + 12 = 0

then simplify some more

9x + 21x = 30x

(-25) + (-35) + 21 + 12 = -13

30x - 13 = 0

now add 13 to both sides, 13 and -13 cancel each other out and it becomes

30x = 13

then you divide by 30 to get x by itself. 30 cancels itself out and you are left with 13/30 which doesn't simplify so that shod be your answer! I couldn't figure out 14 but I hope this helps!!!

Verify that f and g are inverses functions using composition , show your steps
pshichka [43]

Answer:

See explanations below

Step-by-step explanation:

Given the functions

f(x) = 12x - 12

g(x) = x/12 - 1

To show they are inverses, we, must show that f(g(x)) = g(f(x))

f(g(x)) = f(x/12 - 1)

Replace x with x/12 - 1 into f(x)

f(g(x)) =12((x-12)/12) - 11

f(g(x)) =  x-1 - 1

f(g(x)) =x - 2

Similarly for g(f(x))

g(f(x)) = g(12x-12)

g(f(x)) =(12x-12)/12 - 1

12(x-1)/12 - 1

x-1 - 1

x - 2

Since f(g(x)) = g(f(x)) = x -2, hence they are inverses of each other

PLS,PLS,PLS,PLS HELP ME THIS QUESTION IS WORTH 10 POINTS. Which number sequence follows the rule add 4 starting from 2?
saul85 [17]

Answer:

Arithmetic sequence

Step-by-step explanation:

In an arithmetic sequence, the next term on the sequence is obtained by adding a certain value to the first term. This term that is added is uniform throughout the sequence. Once this term is added to the preceding term, the next term of the sequence is obtained. This term that is thus added is known as the common difference of the arithmetic sequence.

So the arithmetic sequence obtained by adding 4 starting from 2 is; 2, 6, 10, 14 .........

Michael washes the Gomez family’s cars once a month they pay him $25 every 3 months for his work at this rate how much will Mich
kakasveta [241]

So you need to see how many times they get paid in a year. 12 months ÷ by every 3= 4. So then you multiply the $25 by 4. Which equals $100.
