What is the inverse of the function below?

F(X)=x/4-2

A. F-^1(X)=2(X-4)

B. F-^1(X)=4(X-2)

C. F-^1(X)=4(X+2)

D. F-^1(X)=2(x+4)

Answer:

[tex]t = \frac{2-3q}{q+4}[/tex]

Step-by-step explanation:

[tex]q = \frac{2-4t}{t+3}\\\\[/tex]

Cross multiply,

q(t+3) = 2 - 4t        

Use distributive property: a*(b + c) =(a*b) + (a*c)

qt + 3q = 2- 4t

qt + 4t + 3q = 2

  qt + 4t     = 2 - 3q

    t(q + 4)  = 2 -3q

               [tex]t = \frac{2-3q}{q+4}[/tex]

Answer:

-21 tickets per hour

Step-by-step explanation:

I think it's right

Answer:

Therefore, the correct answer is option C. 21 tickets per hour.

Step-by-step explanation:

Given: the opening day ticket sales for the park is given by the function[tex]T(h)=\frac{386+110h}{h}[/tex] where [tex]T(h)[/tex] represents the number of tickets sold [tex]h[/tex] hours after opening at 7:00 a.m.

To find: the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m.

For 10 a.m., [tex]h=3[/tex]

So the number of tickets sold upto 10 a.m. are,

[tex]T(3)=\frac{386+110 (3)}{3}[/tex]

[tex]T(3)=238.67[/tex]

Similarly, for 1 p.m., [tex]h=6[/tex] hours

So, the number of tickets sold in 6 hours are,

[tex]T(6)=\frac{386+110(6)}{6}[/tex]

[tex]T(6)=174.33[/tex]

Now, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is,

[tex]\frac{T(6)-T(3)}{6-3}[/tex]

[tex]=\frac{174.33-238.67}{3}[/tex]

[tex]=-21.445[/tex]

which is approximately [tex]-21[/tex] tickets per hour.

Hence, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is -21 tickets per hour.

The correct answer is option C.

Answer:

12 fish are girls

Step-by-step explanation:

multiply 4/6 by 6 which would be 24/36. Then substract 24 from 36 and you get 12.

Answer:

12 are girls

Step-by-step explanation:

Reason that since 4/6 of them are boys then that means 2/6 are girls

then convert 2/6 to decimal form which is 0.3333....

then multiply that by 36 which gives us 12

you could also go the roundabout way and convert 4/6 to decimal form and take that value and multiply it by 36 which gives us 24 then subtract 24 from 36 which still gives us 12

where  is the slope and  and  are the points where the line passes.

in this case we have that the first point is: (25,50)  thus⇒  and

and the second point: (80,110) thus ⇒  and

substituting this values into the formula for the slope:

the slope of the line is 12/11

  22 nickels

Step-by-step explanation:

Let n represent the number of nickels in Joseph's piggy bank. Then the number of quarters is 62-n. The total value is ...

  0.05n + 0.25(62 -n) = 11.10

  -0.20n + 15.50 = 11.10 . . . simplify

  4.40 = 0.20n . . . . . . . . . . add 0.20n-11.10

  4.40/0.20 = n = 22

Joseph has 22 nickels in his piggy bank.

Answer:

Step-by-step explanation:

8/24 are Red

Pick and return 2

So it will be 7/25

Again pick and return 2

Then it is 6/26

Now multiply the results

8/24 × 7/25 × 6/26 = 7/ 325

The probability that all three discs are taken out of red will be 7/ 325.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Given that a bag contains 24 discs. 8 are red and 16 are blue. One disc is taken out at random and replaced by two of the other colour. Another disc is then taken out at random and replaced by two of the other colour.

The probability will be calculated as,

Red = 8/24

Pick and return 2 it will be 7/25

Again pick and return 2 then it is 6/26

Now the overall probability will be,

P = 8/24 × 7/25 × 6/26 = 7/ 325

Therefore, the probability that all three discs are taken out of red will be 7/ 325.

Answer:

m<Y = 68°

Step-by-step explanation:

A tangent drawn to a circle makes a 90° angle with the radius that intersects it at the point of tangency. That means that m<X = 90°.

The sum of the measures of the angles of a triangle is 180°.

m<X + m<Y + m<Z = 180

90 + m<Y + 22 = 180

m<Y + 112 = 180

m<Y = 180 - 112

m<Y = 68
