What is the value of h(-7) h(x) =|3x| -1

Mathematics
1 answer:
Art [367]4 years ago
6 0

Answer:

20

Step-by-step explanation:

h(-7) just means that inside the x value, you replace the x with a -7.

h(-7) = |3x| - 1

h(-7) = | 3(-7)| - 1

h(-7) = | -21 | - 1

NOTE: -21 is inside |x|, those straight lines mean absolute value. No matter what, any negative number would turn into a positive one. And if it’s posititve, then it stays positive.

h(-7) = 21 - 1

h(-7) = 20

Jane purchased a concert ticket on a web site. The original price of the ticket was $55. She used a coupon code to receive a 20%
Licemer1 [7]

Answer:

28%

Step-by-step explanation:

-The price after the coupon discount is calculated as;

P_{ad}=P_r(1-d)\\\\=55(1-0.2)\\\\=\$44

We reduce the discounted price by the service fee to determine the effective purchase price:

P_f=P_{ad}(1-f)\\\\=44(1-0.1)\\\\=\$\ 39.6

#Compare this final price to the original price:

\bigtriangleup=1-\frac{Final}{Original}\\\\=1-\frac{39.6}{55}\\\\=0.28 \ \ or \ 28\%

Hence, the final price was 28% less than the original price.
