Each day, a young person should sleep 9 hours plus 1 4 hour for each year that the person is under 18 years of age. Assuming the

Andre45 [30]

Answer:

$y(x) = 9 + 0.25*(18 - x)$

Step-by-step explanation:

We have the following variables:

y: hours of sleep

x: age

Each day, a young person should sleep 9 hours

This means that y is 9 added to something

plus 1 4 hour for each year that the person is under 18 years of age.

For each year the person is under 18 years of age, she should sleep 1/4 = 0.25h on top of the 9 hours.

So the equation relating hours of sleep y and age x is:

$y(x) = 9 + 0.25*(18 - x)$

2+4z-18 slove step by step

Marianna [84]

2+4z-18
change it so it's an equation
2+4z-18=0
then get 4z alone on one side by subtracting 4z from both sides
2-18=-4z
-16= -4z
divide both sides by -4

a negative divided by a negative becomes positive
4 =z
plug it in
2+4(4)-18
4x4 is 16
2+16-18=0
0=0

the same can be done for the second one 2+k-8

make it 2+k-8=0

move the k to get it alone so subtract k from both sides

2-8=-1k

-6 = -1K

you can divide by K to make K=6

plug in 2+6-8=0

0=0
