4 0

Answer:

Step-by-step explanation:

f(0) is just the function f(x) evaluated at 0, meaning we need to plug in 0 to the function.

What piece of this function should we plug 0 in? Well, because 0 is less than 5, plug it into the first piece.

so f(0) = 0 + 4 = 5

By similar reasoning:

f(6) = 8

because 5 <= 6 < 7

Toys R us is having a 38% off sale on all of their backpacks.If a backpack normally cost 22.00 how much will it be on sale

vovangra [49]

Answer:

$13.64

Step-by-step explanation:

The backpack is originally priced at $22. During the sale, the price would be 38% off which means you pay 62% of the original price. We can find this by multiplying by the percent 62 (converted into a decimal).

22(0.62)=13.64

The sale price at the sale is $13.64.
