If you wish to find the inverse of y=mx you must solve for x and then switch the labels for the varibles.  (because the inverse of a function is really just switching of x and y coordinate pairs to y and x coordinates)

y=7.5x  divide both sides by 7.5

y/7.5=x  now switch variable labels...

y=x/7.5

You pick 5 digits (0-9) at random without replacement, and write them in the order picked. What is the probability that you have
Tanzania [10]

Answer:

Probability is : 1/30240= 0.000033068

Step-by-step explanation:

You pick 5 digits (0-9) at random without replacement, and write them in the order picked.

The probability that you have written the first 5 digits of your phone number is -

As there are no repeats, the choice to choose from decreases at each step making it 10,9,8,7,6.

(1/10)(1/9)(1/8)(1/7)(1/6)=1/30240= 0.000033068

For a school play, Rico bought 3 adult tickets and 5 child tickets for $40. Sasha bought 1 adult ticket and 5 child tickets for
Serhud [2]

The cost of one adult ticket is $7.5 and one child ticket is $3.5

Julia will pay $48 for 5 adult tickets and 3 child tickets.

Step-by-step explanation:

Let,

Cost of one adult ticket = x

Cost of one child ticket = y

According to given statement;

3x+5y=40    Eqn 1

x+5y=25      Eqn 2

Subtracting Eqn 2 from Eqn 1

(3x+5y)-(x+5y)=40-25\\3x+5y-x-5y=15\\2x=15

Dividing both sides by 2

\frac{2x}{2}=\frac{15}{2}\\x=7.5

Putting x=2.5 in Eqn 1

3(7.5)+5y=40\\22.5+5y=40\\5y=40-22.5\\5y=17.5

Dividing both sides by 5

\frac{5y}{5}=\frac{17.5}{5}\\y=3.5

The cost of one adult ticket is $7.5 and one child ticket is $3.5

5 adult tickets = 5*7.5 = $37.5

3 child tickets = 3*3.5 = $10.5

Total = 37.5+10.5 =$48

Julia will pay $48 for 5 adult tickets and 3 child tickets.
