Answer: Only B

============================================

Explanation:

For situation A,

The pairing (x,y) tells us what a certain student likes in terms of color.

For example, the point (Allen, Red) tells us that Allen likes the color red. We could also have (Allen, Green) telling us he also likes green. Because the input "Allen" maps to more than one output, this means situation A is not a function. A function is only possible if any given input maps to exactly to one output. The input must be in the domain. The domain in this case is the set of all students in the classroom.

In contrast, Situation B is a function because a student will only have one favorite math teacher. I'm interpreting this to mean "number one favorite" and not a situation where a student can select multiple favorites.

Answer:

x = 11

y = 3

Step-by-step explanation:

In a parallelogram opposite sides are equal.

8x = 88

x = 88/8

x = 11

4y - 7 = y + 2

4y      = y + 2 + 7

    4y = y + 9

4y - y = 9

       3y =  9

         y = 9/3

        y = 3

Answer:

Difference = 36

Step-by-step explanation:

Given that,

The boiling point of Oxygen = -183

The melting point of Oxygen = -219

We need to find the temperature difference of the melting point and the boiling point.

Difference = boiling point - melting point

= -183-(-219)

= -183+219

= 36

Hence, the required temperature difference is 36.

Step-by-step explanation:

Answer:

x = 3, x = 11

Step-by-step explanation:

Since PR is an angle bisector then it divides the opposite side into segments which are proportional to the other 2 sides, that is

[tex]\frac{PQ}{PS}[/tex] = [tex]\frac{QR}{SR}[/tex] , substitute values

[tex]\frac{x+1}{16}[/tex] = [tex]\frac{x-2}{x+1}[/tex] ( cross- multiply )

(x + 1)(x + 1) = 16(x - 2) ← expand left side using FOIL

x² + 2x + 1 = 16x - 32 ( subtract 16x - 32 from both sides )

x² - 14x + 33 = 0 ← in standard form

(x - 3)(x - 11) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 11 = 0 ⇒ x = 11

Equality Properties

Step-by-step explanation:

Step 1: Define

5(x - 8) + 7 = 2

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 2 does indeed equal 2.

∴ x = 7 is the solution to the equation.

Answer:

27

Step-by-step explanation:

In this case, because we have a polynomial where all x-values exist, we can plug the value (x=2) straight into the function:

[tex]\lim_{x \to \ 2} (2x^3+x^2+7)[/tex]

[tex]= 2(2)^3+(2)^2+7[/tex]

[tex]= 2(8)+4+7[/tex]

[tex]= 27[/tex]

The limit of (2x^3+x^2+7) as x approaches 2 equals 27, which makes sense since the value of (2x^3+x^2+7) at x = 2 is 27.

Answer:

$1032.60

Step-by-step explanation:

Given data

salary = $950 every two weeks

tax rate = 8%

let the initial pay be x

and let the pay after tax deduction be p

p= x-8/100x

Hence the equation for his pay is

[tex]p=x-0.08x-------------1[/tex]

subsitute

950=x-0.08x

950= 0.92x

divide both sides by 0.92

x= 950/0.92

x=$1032.60

The employee make $1032.60 every two weeks before taxes

Answer:

divide the cost by the amount.

4.95/5 = 0.99

8.50/10 = 0.85 (better buy)

3.59/3 = 1.20

4.99/5 = 1.00 (better buy)

1.25/16 = 0.078125

1.55/20 = 0.0775 (this one is the better buy however when you round to 2dp they are both the same price of 0.08.)

Answer:

40

Step-by-step explanation:

so she saved 10 dollars

then 50-10=40

so she paid 40 dollars

Answer:

25 in

Step-by-step explanation:

Hypotenuse is the longest side in the right angle triangle. It is proven by the fact that the square of hypotenus is the sum of the squares of the two other sides.    

The hypotenuse of the Pythagorean triple 25 in, 15 in, 20 in is 25 in

The Pythagoras theorem is used to find the sides of a right angle triangle. The formula below is used to find the sides of a right angle triangle(Pythagoras's theorem) is represented below

where

c = hypotenuse

a and b are either opposite or adjacent sides

A right angle triangle is a triangle that has one of its angles as 90°.

A right angle triangle has the following sides :

The longest side of a right angle triangle is the hypotenuse. Base on the Pythagorean triple, the hypotenuse is 25 inches because its the longest side.

Answer:

Step-by-step explanation:

1 yard is about 36 inches.

A square yard in square inches will therefore be:

= 36 * 36

= 1,296 inch²

He needs 497 square inches of gray fabric. In square yards that will be:

= 497/1,296

= 0.38 yard² of gray material

He needs 746 square inches of yellow:

= 746/1,296

= 0.58 yard² of yellow.
