Answer:
f(4) = 85 1/3 or 85.333...
Step-by-step explanation:
To find f(4), you must substitute 4 in place of x whenever x appears:
f(x) =
*
f(4) =
* 
Next, simplify the exponent:
f(4) =
* 256
Finally, multiply:
f(4) = 85 1/3 or 85.333...

Answer:
- x > -2
- n ≤ -2 or n ≥ 8
Step-by-step explanation:
<h3>1.</h3>
Add 7x-2 to both sides and collect terms.
2x +2 -6x +7x -2 > -4 -7x +7x -2
3x > -6
x > -2 . . . . . . . divide by 3

<h3>2.</h3>
Solve these one at a time, and form the union of the answers.
1 +7n ≤ 15 . . . .given
7n ≤ 14 . . . . . . subtract 1
n ≤ 2 . . . . . . . divide by 7

n ≥ 8 . . . . . . . . divide by -2
The solution is n ≤ -2 or n ≥ 8.
Answer:
<em>C. 1/10 • 33</em>
<em>D. 0.1 • 33</em>
<em>E. 10/100 • 33</em>
Step-by-step explanation:
Knowing that
10% = 0.1 in decimal form
10% = 1/10 or 10/100 in fraction form
of = multiply
<em>Thus, the following is correct:</em>
<em>C. 1/10 • 33</em>
<em>D. 0.1 • 33</em>
<em>E. 10/100 • 33</em>
<u><em>We can also solve to find the answer:</em></u>
<em>10% of 33 = 3.3</em>
<em>0.1 x 0.33 = 0.033</em>
<em>10 x 33 = 330</em>
<em>1/10 x 33 = 3.3</em>
<em>0.1 x 33 = 3.3</em>
<em>10/100 x 33 = 3.3</em>
<u><em>Hence answer =</em></u>
<em>C. 1/10 • 33</em>
<em>D. 0.1 • 33</em>
<em>E. 10/100 • 33</em>
