Domain: all real numbers

Range: all real numbers greater than or equal to -2

Step-by-step explanation:

The domain is the set of x-coordinates.

It is the set of real numbers since x can be any real number.

The range is the set of y-coordinates.

The minimum value for y is -2. y can be -2 or any real number greater than -2.

1. Judy took $15 with her to spend on popcorn and drinks for herself and her friends at the movie theater. The price for each bag of popcorn was $3. The price of each drink was half the price of a bag of popcorn.
(a) Sketch the graph that represents the situation and label the intercepts. Use one axis to represent the number of bags of popcorn and the other axis to represent the number of drinks
I cant figure it out-

Answers

You know that the popcorn cost $5.00 so the drinks would cost $2.50 each. So when you plot the points you would reach $10.00 for popcorn and have $5.00 for drinks. $15.00 for popcorn and $7.50 for drinks.

Step-by-step explanation:

Judy has $30 to spend.

The price per bag of popcorn is $5.

The price per drink is $2.50.

Answer:

The constant of proportionality is 3.50.

Step-by-step explanation:

We know that when y directly varies with x, such that

[tex]y=kx[/tex]

The number 'k' is called the constant of proportionality.

Given the equation

[tex]y=3.50x[/tex]

as

[tex]y=kx[/tex]

so

[tex]k=3.50[/tex]           ∵ [tex]y=kx[/tex]

Here the value of k = 3.50, which is the constant of proportionality.

Therefore, the constant of proportionality is 3.50.

This question is incomplete

Complete Question

An arts academy requires there to be 6 teachers for every 132 students and 4 tutors for every 44 students. How many students does the academy have per​ teacher? Per​ tutor? How many tutors does the academy need if it has 132 students​?

Answer:

a)How many students does the academy have per​ teacher?

22 students per teacher

b) Per​ tutor?

11 students per tutor

c) How many tutors does the academy need if it has 132 students​?

12 tutors

Step-by-step explanation:

a)How many students does the academy have per​ teacher?

6 teachers = 132 students

1 teacher = x

6 × x = 132 × 1

x = 132 × 1/6

x = 22 students

Hence, we have 22 students per tutor

b) Per​ tutor?

4 tutors = 44 students

1 tutor = x students

Cross Multiply

4 × x = 1 × 44

x = 44/4

x = 11 students

Hence, we have 11 students per tutor

c) How many tutors does the academy need if it has 132 students​?

44 students = 4 tutors

132 students = x tutors

Cross Multiply

44 × x = 132 × 4

44x = 132 × 4

x = 132 × 4/44

x = 12 tutors

The academy needs 12 tutors if they have 132 students.

Elena knows that 5 servings of granola have 1,750 calories. if she eats 2 servings of granola,how many calories dose she eat

Answers

Answer:

700 calories

Step-by-step explanation:

1,750/5

=350

350colories per serving

So multiply 350 by 2

350x2

=700

Answer:

Elena eats 700 calories

Step-by-step explanation:

First, we need to find out how many calories are in one serving of granola. To do that, we will divide; 1750/5=350. We now know that there are 350 calories in one serving of granola. However, the problem is asking for how many calories are in two servings of granola. 350 x 2 = 700. Therefore, Elena eats 700 calories.

2(15+6y)+5y=9 someone help me

Answers

Answer:

y=-21/17

Step-by-step explanation:

Answer:

y= - 21/17

Step-by-step explanation:

Rearrange terms:

2(15+6y) +5y =9

2(6y+15)+5y=9

Distribute:

2(6y +15) +5y=9

12y+30 + 5y = 9

Combine like terms:

12y+30+5y =9

17y+30 =9

Subtract 30 from both sides:

17y+30 =9

17y +30 -30 =9-30

Simplify:

17y=-21

Answer:

Step-by-step explanation:

1. Divide both sides by -2 to get x by itself

-2x/-2=-8/-2....

x=4

2. Add 4 to both sides and then divide by -2

-2x-4+4=-18+4

-2x/-2=-14/-2

x=7

3. Distribute, add 12 to both sides and then divide by 3

3x-12=-18

3x-12+12=-18+12

3x/3=-6/3

x=-2

4. Add 5 to both sides

x-5+5=-7+5

x=-2

5. Distribute, add 4 to both sides, divide both sides by 4

Step-by-step explanation:

1.) Add +5x on both sides

-5x + 8 < - 2x + 23

+5x         +5x      

8    <    3x + 23

2.) Subtract 23 from both sides

8    <    3x + 23

-23            -23

-15  <  3x

3.) Divide by 3 on both sides

-15 <  3x

Answers

Answer:

-2.50

Step-by-step explanation:

Using the formula for the expected value, it is found that the expected pay off is of -$1.

The expected value is given by the sum of each outcome multiplied by it's respective probability.

In this problem, the outcomes and probabilities are, considering the cost of the game of $5 and that there are 6 sides:

[tex]\frac{3}{6}[/tex] probability of losing $5.[tex]\frac{2}{6}[/tex] probability of winning $2.[tex]\frac{1}{6}[/tex] probability of winning $5.

Hence:

[tex]E(X) = \frac{3}{6}(-5) + \frac{2}{6}(2) + \frac{1}{6}(5) = \frac{3(-5) + 2(2) + 1(5)}{6} = -\frac{6}{6} = -1[/tex]

The expected pay off is of -$1.
