For the following exercises, determine whether the functions are even, odd, or neither.

stealth61 [152]

Answer:

The solutions of the equation |2 x-3|=17

are x=10

and x=-7

Step-by-step explanation:

Given equations is |2 x-3|=17.

It is required to find out the values of x satisfying the given equation.

To find it out, use the fact that the solution of this type of equation is 2x-3=17.

Or 2x-3=-17 and simplify the equations using simple mathematical operations.

Step 1 of 2

Solve the equation 2x-3=17,

Add 3 on both sides of the equation 2x-3=17,

2x-3+3=17+3

2x=20

Divide by 2 on both sides of the equation 2x=20,

$\begin{aligned}&\frac{2 x}{2}=\frac{20}{2} \\&x=10\end{aligned}$

Step 2 of 2

Solve the equation 2x-3=-17,

Add 3 on both sides of the equation 2x-3=-17,

$2 x-3+3=-17+3$\\ $2 x=-14$

Divide by 2 on both sides of the equation 2x=-14,

$\begin{aligned}&\frac{2 x}{2}=\frac{-14}{2} \\&x=-7\end{aligned}$

Answer:

5621 years

Step-by-step explanation:

Plug everything in first.

$N=N_0e^{-kt}\\\\\implies 0.57 = e^{-0.0001t}\\\\\implies\ln \left(0.57\right)=-0.0001t\\\\t=-\frac{\ln \left(0.57\right)}{0.0001}$

Round to closest amount of years = 5621 years

Varia is studying abroad in Europe. She is required pay $3,500 (in US dollars) per year to the university; however, she must pay

natulia [17]

Answer:

She could expect to pay 213 euro per month ⇒ answer A

Step-by-step explanation:

* Lets explain how to solve the problem

- Varia is studying abroad in Europe

- She is required pay $3,500 (in US dollars) per year to the university

- She must pay in euros

- 1 US dollar = 0.7306 euros

- We want to know how many euros could she pay per month

* At first lets change the US dollars to euro

∵ 1 US dollar = 0.7306 euros

∵ She is required pay $3,500 (US dollars)

∴ 3,500 × 0.7306 = 2557.1 euro

∵ She required to pay 2557.1 euro per year

∵ One year = 12 months

- Divide the amount of money per year by the 12 months

∵ 2557.1 ÷ 12 = 213.09

∴ She could expect to pay 213 euro per month
