Answer: 8-7x=22
8-22=7x
7x=8-22
7x=-14
x=-14/7
x=-2

Answer 2

Answer: taking 8 to the right hand side,
-7x=22-8
x=14/(-7)
x=-2

the answer is 5/42 multiply 1*5=5 and 6*7=42 the 5 is the numerator and the denominator is 42 so you get 5/42.

Given the function f(x)=0.3(4)x
what is the value of
f−1(6)

a. 0.360
b. 1.242
c. 2.161
d. 2.312

Answers

For this case we have the following function:
$f (x) = 0.3 (4) ^ x$
Rewriting we have:
$y = 0.3 (4) ^ x$
From here, we clear the value of x:
$(4) ^ x = y / 0.3log4 ((4) ^ x) = log4 (y / 0.3)$
Rewriting we have:
$x = log4 (y / 0.3)$
Therefore, the inverse function is given by:
$f ^ {-1} (x) = log4 (x / 0.3)$
For x = 6 we have:
$f ^ {-1} (6) = log4 (6/0.3)f ^ {-1} (6) = 2.161$
Answer:
is the value of f^-1(6) is:
c. 2.161

f(x)=0.3(4)^x

f^-1(x) = ?

x = 0.3(4)^y

4^y = x/0.3

4^y = 6/0.3

4^y = 20

y = 2.161

Cynthia's credit card has a limit of $1,000 with an introductory rate of 0%, a late fee of $35, and currently a balance of $0. The card also has an annual fee of $45 which is applied every year in August. Cynthia makes a $75 purchase that shows up on her August bill and she pays $45 before the due date. What will be the balance on Cynthia's credit card?$45

$65

$35

$75

Answers

The balance will be 75 dollars.
Because August is the month in which her annual fee for her credit card charges and she only paid 45 dollars which is for the annual fee. The 75 dollars that she purchased is not yet paid.

If 12 cows produce 70 gallons of milk, how many gallons of milk would 42 cows produce?A. 20
B. 245
C. 512
D. 840

Answers

This is a proportions question
12 42
------ = -------
70 ?

Cross multiply

70x42=2940
12x?=2940
294/12=245

42 cows can produce 245 gallons of milk.
So the answer is B.

Hope I helped!

Answer: 245 gallons

Step-by-step explanation: Set up a ratio, cows/gallons = 12/70 = 42/x, then cross multiply to get 12x = 70*42. Divide to get 245 gallons.
