Hillel is juggling flaming torches to raise money for charity. His initial appearance raises $500, and he raises $15 for each mi

Sauron [17]

Answer:

$R(t)=15t+500$

Step-by-step explanation:

Let R be the amount of money Hillel raises is a function of t, the length of his performance in minutes.

We have been given that Hillel raises $15 for each minute of juggling performance. This means that change in amount of money with every minute of juggling performance is 15, so slope of our line will be 15 and money raised in t minutes of performance will be 15t.

His initial appearance raises $500, so 500 will be our y-intercept.

The total money raised by Hillel after t minutes of juggling performance will be: $500+15t$ .

Since we know that line of an equation in slope-intercept form is: $y=mx+b$ , where,

m = slope of line,

b = y-intercept.

We are also given that R is a function of t, so substituting our given values in slope-intercept form of equation we will get our function formula as:

$R(t)=15t+500$

Therefore, the function $R(t)=15t+500$ gives the amount R of money Hillel raises in t minutes of juggling performance.

Help! Need by 10:30 to turn in and I'm confused!

Alecsey [184]

Answer:

8 boxes of tissues

5 bags of cough drops

Step-by-step explanation:

You need to write a system of equations.

x = number of tissue boxes

y = number of cough drop bags

x (number of tissue boxes) + y (number of cough drop bags) = 13 (total number of tissues and cough drops combined.

So, your first equation is

x + y = 13

Then, you need to write the second equation.

(1.69 [cost of 1 tissue box] * [number of tissue boxes]) + (1.19 [cost of one bag of cough drops] * [number of cough drop bags] = 19.47 [total cost of tissues and cough drops]

That's a lot to read, so here's the equation simplified!

1.69x + 1.19y = 19.47

Now, you have two equations:

x + y = 13

1.69x + 1.19y = 19.47

I would solve with the substitution method.

the first equation can be changed to x = 13 - y by subtracting y from both sides.

Then, your two equations are:

x = 13 - y

1.69x + 1.19y = 19.47

Now, you can plug in that value of x into the second equation!

1.69(13 - y) + 1.19y = 19.47

21.97 - 1.69y + 1.19y = 19.47

subtract 21.97 from both sides

-1.69y + 1.19y = -2.5

Add the y values

-0.5y = -2.5

divide both sides by -0.5

so, y equals 5 bags of cough drops

now that you know what y equals, plug it back into your original equation to find x!

x + y = 13

plug in y

x + 5 = 13

x = 8

so, x = 8 boxes of tissues

Hope this helps! Let me know if you have any questions!
