Answer:
f(6) = 82
Step-by-step explanation:
substitute x = 6 into f(x) and evaluate
f(6) = 2(6)² + 5 = 2(36) + 5 = 72 + 5(2) = 72 + 10 = 82
The regular price is $22.5 if everything in a store is 20% off, and the discounted price of an item is $18.00
<h3>What is the percentage?</h3>
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
If everything in a store is 20% off, and the discounted price of an item is $18.00
Let's suppose the regular price is x
(100-20)% of x = 18
80x/100 = 18
x = $22.5
Thus, the regular price is $22.5 if everything in a store is 20% off, and the discounted price of an item is $18.00

The total cost of 12 printers is; $493.41
Cost of first printer; C1 = $54
Cost of second printer is; 95% × 54 = $51.3
Cost of third printer is; 0.95 × 51.3 = $48.735
Cost of fourth printer = 0.95 × 48.735 = $46.298
Now, let us apply same pattern using a calculator for the remaining costs and we will have them as follows;
- Cost of 5th printer = $43.983
- Cost of 6th printer = $41.784
- Cost of 7th printer = $39.695
- Cost of 8th printer = $37.710
- Cost of 9th printer = $35.825
- Cost of 10th printer = $34.033
- Cost of 11th printer = $32.332
- Cost of 12th printer = $30.715
Total cost of the 12 printers is;
54 + 51.3 + 48.735 + 46.298 + 43.983 + 41.784 + 36.695 + 37.710 + 35.825 + 34.033 + 32.332 + 30.715 = $493.41

Answer:
x=18
Step-by-step explanation:
(3x-9)= 45 degrees because the angle you are solving for is half of a right angle (90 divided by 2 = 45)
so you take 45 and add 9 to it. That equals 54. To get the value of x, you divide 54 by 3 and you get 18.
hope this helps!
