Step-by-step explanation:

g(x)=-2x+1

let y=2x+1

Interchanging role of x & y

x=2y+1

y=½x-½

g-¹(x)=½(x-1)

not

equal to f(x)=-x+1

Given function are not function of each other .

g(x)=-x

let

y=-x

Interchanging role of x & y

x=-y

y=-x

g-¹(x)=-x

not

equal to f(x)=3+⅓x

Given function are not function of each other .

Answer:

none of the function pairs are inverses

Step-by-step explanation:

Inverse linear functions will meet all of several requirements:

each is a reflection of the other about the line y=x
the solution of the simultaneous equations in on the line y=x
in standard form, the coefficients are swapped (only)
the product of the slopes is 1

_____

For these problems, it is probably easiest to look at the last requirement. Each function is given in slope-intercept form, so the slope is simply the x-coefficient.

5) The product of slopes is (-2)(-1) = 2 ≠ 1 . . . NOT inverses

6) The product of slopes is (-1)(1/3) = -1/3 ≠ 1 . . . NOT inverses

7) The product of slopes is (-4/3)(-1/2) = 2/3 ≠ 1 . . . NOT inverses

8) The product of slopes is (3/2)(-5/2) = -15/4 ≠ 1 . . . NOT inverses

A fruit basket contains 9 apples, 5 bananas, 1 orange, and 5 peaches. Kirsten picked a banana out of the basket. She looked at i

Pie

Answer

9/20

Step-by-step explanation:

This is a probabilty, problem

firstly, let us bring out the sample space and size

the sample space is

9 apples,

5 bananas,

1 orange, and

5 peaches

The sample size is (9+5+1+5)= 20

The probability of picking a banana is

Pr(banana) =5/20

=1/4

The probability of picking an apple

Pr(apple) = 9/20

The probability of picking up a banana and an apple with replacement is

=1/4+9/20

=9/80

Which of the following options have the same value as 30\%30%30, percent of 818181?

Nataly_w [17]

Answer:

Option B is correct = $0.3 \times 81$

Step-by-step explanation:

The complete question is: Which of the following options have the same value as 30% of 81?

Group of choices is:

(A) $\frac{30}{100}\times 81 \times 100$

(B) $0.3 \times 81$

(D) $\frac{3}{10}\times 81 \times 10$

(E) $30 \times 81$

Now, the expression given to us is 30% of 81.

Simplifying the above expression we get;

30% of 81 = $\frac{30}{100} \times 81$

= $\frac{3}{10} \times 81$ = $0.3 \times 81$

Now, we will solve each of the given options and then see which option matches with our calculation.

Option (A) is given;

$\frac{30}{100}\times 81 \times 100$ = $30 \times 81$

This doesn't match with our answer, so this option is not correct.

Option (B) is given;

$0.3 \times 81$

This matches with our answer, so this option is correct.

Option (C) is given;

$0.03 \times 81$

This doesn't match with our answer, so this option is not correct.

Option (D) is given;

$\frac{3}{10}\times 81 \times 10$ = $3 \times 81$

This doesn't match with our answer, so this option is not correct.

Option (E) is given;

$30 \times 81$

This doesn't match with our answer, so this option is not correct.

Two-fifths of a number is decreased by three. Find the value of the expression if the number is twenty-five.

Sindrei [870]

Let's take the number as x.

two-fifths of a number = 2x / 5
decreased by 3 = (2x/5) - 3

(2x/5) - 3
(2*25/5) - 3
(2*5) - 3
10 - 3
