Answer:
x ≈ {-11.789, +0.501, 11.288}
Step-by-step explanation:
The cubic g(x) - f(x) = 0 has three real solutions. It can be rewritten as ...
Since the solutions are irrational, they are best found using a spreadsheet or graphing calculator. My favorite graphing calculator shows the approximate solutions below.

<em>Comment on the problem statement</em>
Your expression for f(x) is ambiguous in that many Brainly questions have the exponentiation indicator replaced by a blank: 3 x -1 often means 3^x -1 and sometimes means 3^(x-1). We have taken the expression at face value and have assumed it is a linear expression. If otherwise, the problem is basically worked the same way: write a function h(x) = g(x) - f(x) and look for solutions to h(x) = 0. Graphing can be useful.
Answer:
12 and 1/4
Step-by-step explanation:
This is a fairly simply problem all you have to do is all all the fractions given. So we get the equation 4/8 + 5/8 + 5/8 + 1 1/8 + 1 1/8 + 1 4/8 + 1 4/8 + 1 4/8 + 1 6/8 + 2. This makes the equations easy since all the denominators are the same. First we must make all the fractions improper fractions. This will make the equation 4/8 + 5/8 + 5/8 + 9/8 + 9/8 + 12/8 +12/8 + 12/8 + 14/8 + 16/8. Then we can add all the values together and we get 98/8 which simplifies to 12 2/8 which further simplifies to 12 and 1/4.
Answer:
the percentage increase is 360%
Step-by-step explanation:
The computation of the increase in percentage is shown below;
Given that
SOcial security credit as on 1978 is $250
And, the social security tax as on 2008 is $1,150
Now based on the above information
The percentage increase is
= ($1,150 - $250) ÷ ($250)
= 360%
Hence, the percentage increase is 360%
Answer:
a10 = 25
Step-by-step explanation:
I'm not certain that I have interpreted the question in the way it was intended; however, if I have:
a
10 = 3
(10
) − 5 =
30 − 5 = 25
4x = 32 - 2x
Add -2x (or subtract 2x) from each side
2x = 32
Divide both sides by 2
x = 16
