Equation to find number's value: 
Number's value: n = 35
Explanation:
Let n be the unknown number for this problem.
One fifth of a number is the same as
.
Three times the number is the same as 3n.
Twice the number plus 42 is the same as 2n + 42.
So, using the information we've gathered so far, we can create the equation that will provide us with n's value.
Equation: 
We can use this equation to find n's value.
You can subtract 2n from both sides to get the equation
, which is the same thing as the equation we were using.
Now add n and
together to get
.
After you do this, your equation should look like
.
Now divide both sides by
to get n's value.
n = 35
This means which transformation makes the same answer at x = 0
f(x) = 3x + 4

f(0) = 4
g(0) = 1 - 1 = 0
Which transformation makes 4 = 0?
4 + x = 0 + y
4 - 3 =0 + 1
1 = 1
Option 1 is your answer
Answer: It is 46.667 percent decrease
Step-by-step explanation:
To get the answer you subtract the two values first.
15-8=7
Then divide the answer by the original value. 7/15=0.46667
Then multiply the answer by 100
0.46667x100=46.667
And there you have it. Round as necessary.
