Answer:

the first answer option

Step-by-step explanation:

|x + 4| = 2

so,

(x + 4) must be +2 or -2 to make the original equation true.

when is (x + 4) = 2 ?

x + 4 = 2

x = -2

when is (x + 4) = -2 ?

x + 4 = -2

x = -6

so, -6 and -2 are the correct solutions.

The table below shows some inputs and outputs of the invertible function f with domain all real numbers.
Naddik [55]

by the inverse function definition, we will have that:

  • f⁻¹(-2) = 3
  • f⁻¹(1) = 0

<h3>How to find the values of the inverse function?</h3>

Remember that, by definition, for an invertible function f(x) we have that:

f(x) = y

then:

f⁻¹(y) = x

Where f⁻¹(x) is the inverse function of f(x).

Now, we want to find:

f⁻¹(-2)  and f⁻¹(1)

If you look at the given table, we can see that we have the points (3, -2) and (0, 1), which means that:

f(3)= -2

f(0) = 1

Then, by the inverse function definition, we will have that:

  • f⁻¹(-2) = 3
  • f⁻¹(1) = 0

The fractions with numerator is one and the denominator is any positive integer. Such fractions are called unit fractions.

It is also defined as the reciprocal of the any positive integers.

Example of the unit fractions are

\frac{1}{2},  \frac{1}{10}, \frac{1}{50}, \frac{1}{100}, . . .

The fraction with numerator is any number other one is called

the non-unit fractions.

The sum of a number and two times a smaller number is 98. The bigger number is 22 less than three times the smaller number.
notsponge [240]
The answer is 50 and 24

The two equations are x + 2y = 98   and   x = 3y - 22

every answer equals 98 when you use the first equation but the only one that works with the second equation is C (works meaning when you plug in the answers from the answer choices) 

x = 3(24) - 22

x = 50
