The true statement is that the domain of the functions is all real greater than or equal to 0. This is 0 and all positive real numbers.

This is because the square root, in the set of the real nuimbers, is not defined for the negative numbers.

The range is also 0 and positive real numbers.

Gracie’s insurance premiums are $150 per month. This year she also paid a $500 deductible and 20% of $3,000 for a minor accident
storchak [24]
Her insurance premiums are 150 per month.....there is 12 months in a year....so in 1 year, her premiums totaled : (150 * 12) = 1800

she paid a $ 500 deductible

she paid 20% of $ 3000 for the accident..
0.20 * 3000 = $ 600

therefore, her total healthcare expenses for 1 yr totaled :
1800 + 500 + 600 = $ 2900 <==

How come it’s a right triangle, I think you do a2+b2=C2. Therefore, you do 9.4 times 9.4 and then 15.1 times 15.1. So it will be 9.4 + b2=15.1. 88.36+ b2=228.01. Then you subtract that and it will be 139.65. Then you do square roots because you are trying to get rid of the second power. And the final answer is 11.81736011. How they told you to round it to the nearest tenth, I will be 11.8. I think this is the answer.

|13x-4|+12 &lt; 56<br> Anybody know this cuz I do
Ronch [10]

Answer:

\displaystyle x\in \left(-\frac{40}{13},\frac{48}{13}\right)

Step-by-step explanation:

<u>Inequalities with Absolute Value</u>

We must recall the following rule:

\text{If  }|M|0

Then:

-N

We have the following inequality:

|13x-4|+12 < 56

Subtracting 12:

|13x-4|< 56-12

|13x-4|< 44

Applying the rule:

-44

Adding 4:

-44+4

Operating:

-40

Dividing by 13:

\displaystyle -\frac{40}{13}

The solution expressed in interval form is:

\boxed{\displaystyle x\in \left(-\frac{40}{13},\frac{48}{13}\right)}
