Answer:

y=7/4x-11/2

Step-by-step explanation:

Move the Y and x values to separate sides

-4y=-7x+22

divide whatever it takes to make y alone (dived by -4)

y=7/4x-11/2

Tickets to a movie cost $7.25 for adults and $5.50 for students a group of friends purchased 8 tickets for $52.75 how many adult
irina1246 [14]

Answer:

The number of adults tickets and student tickets purchased is 5 and 3.

Given that,

Tickets to a movie cost $7.25 for adults and $5.50 for students.

A group of friends purchased 8 tickets for $52.75.

Here we assume the no of adult tickets and no of student tickets be x and y.

Based on the above information, the calculation is as follows:

7.25x + 5.50y = 52.75 .............(i)

x + y = 8

x = 8 - y..................(2)

Now put the x value in the equation (1)

So,  

7.25(8-y) + 5.50y = 52.75

7.25 × 8 - 7.25y + 5.50y = 52.75

58 - 1.75y = 52.75

5.25 = 1.75y

y = 3

So,  

x = 8 - 3

= 5

Therefore we can conclude that the number of adults tickets and student tickets purchased is 5 and 3.

Nuno set up a series of dominoes. he starts by knocking over 10 dominoes. every second after that, the number of dominoes that a
vesna_86 [32]
It will take 8 seconds for all of the dominoes to fall over.

This will be an exponential function.  To find the growth rate, we can write out the terms of the sequence that goes along with it:  10, 20, 40, ...

"Growth rate" is the same as percent of increase or decrease.  We find the amount of increase and divide by the original amount:  20-10 = 10 increase; 10/10 = 1.

The exponential function is of the form
f(x) = a*(1+r)ˣ, where a is the initial value (10), r is the growth rate (1), and x is the number of time periods.  Using the variables given to us in the problem along with this information, we have:

d(s)=10(1+1)^s&#10;\\&#10;\\2560=10(2)^s

Divide both sides by 10:
\frac{2560}{10}=\frac{10(2)^s}{10}&#10;\\&#10;\\256=2^s

We will use logarithms to solve this:
\log_2 256=s&#10;\\8=s
