Answers

Answer:

The range is 13.

Step-by-step explanation:

The definition of the range is to subtract the largest number from the smallest number. Looking at this set of numbers, the largest number is 30, and the smallest number is 17. When you subtract 30 - 17 you end up with 13.

Given the point (5, 6) and the slope of 5, find y when x = 21.

Answers

Answer:

y = 86

Step-by-step explanation:

We know the slope is 5 so we can write our equation like this:

y = 5x + b

Since we know that (5, 6) is on our equation, we can substitute it into our equation:

6 = 5(5) + b

b = 6-25 = -19

Now we know our equation is y = 5x - 19

Next, we plug in 21 for x to find our y-value:

y = 5(21)-19 = 105-19 = 86

Find the cost per visit to the nearest cent: Health and Heart Club, $259 per year, 3 visits per week.


$7.19


$1.66


$3.32


$156

Answers

Answer: The answer is A $1.66

Step-by-step explanation: We have been given that Health and Heart Club charges $259 per year. A person has 3 visits per week. We are asked to find the cost of per visit to Health and Heart Club.We know that there are 52 weeks in one year. So total visits in one year would be 3 times 52 that   156 visits.

Now, we will divide total cost by 156 to find cost per visit.

Cost per visit = $1.660256

Rounding to nearest hundredths, we will get: Cost per visit = $1.66

Therefore, the cost per visit is $1.66 and option 'a' is the correct choice.

Make 'y' the subject of the formula: 17t+3hy=24

Answers

Answer:

y=[tex]\frac{24-17t}{3h}[/tex]

Step-by-step explanation:

Hi there!

We are given the formula 17t+3hy=24

We want to make y the subject of the formula, which also means that we want to solve the equation for y

To do that, we'll need to isolate y on one side, much like solving for an equation with real numbers.

Let's first subtract 17t from both sides.

17t+3hy=24

-17t         -17t

___________

3hy=24-17t

Now on the left, we have 3hy, but remember; we want just y by itself. Once again, similar to solving an equation with real numbers, we can pretend that 3h is the coefficient of the equation, while y is our variable.

So to get y by itself, we'll need to divide both sides by 3h

y= [tex]\frac{24-17t}{3h}[/tex], which can also be written as y=[tex]\frac{8}{h} -\frac{17t}{3h}[/tex]

Hope this helps!

Graph: y–3=1/2(x+2) ​

Answers

Answer:

Step-by-step explanation:

Solve the  y

y -3 = 1/2(x + 2)

y =  1/2(x + 2) + 3                Add

Pick  points that you wish to substitute for x values.

       x = 0                                   x  = 2                                       x = 4

  y = 1/2(x + 2) + 3                y = 1/2(x + 2) + 3               y = 1/2(x + 2) + 3

  y = 1/2(0 + 2) + 3               y = 1/2(2 + 2) + 3               y = 1/2(4 + 2) + 3

    y = 1/2(2) + 3                    y = 1/2(4) + 3                     y = 1/2(6) + 3

    y = 1 + 3                            y = 2 + 3                            y = 3 + 3

    y = 4                                 y = 5                                  y = 6
