What are the correct answers ABCD?

Answer:

Step-by-step explanation:

The domain is the set of x values and the range is the set of y values.

For the relation to the function, each value of x must map onto no more than one value of y.

Answer:

The Domain is -2 [is less than or equal to] x < 0

The Range is 0 [is less than or equal to]  y < 2

This is NOT a function

Step-by-step explanation:

sry if this is a bit confusing:

[is less than or equal to] is just the sign that means what is said; this is bc you cant use that sign on keyboard

The two numbers are 6 and 8.

The first step is to determine the simultaneous equations that would be used to determine the answer. The simultaneous equations would be derived from the information provided in the question.

x + y = 14 equation 1

x - y = 2 equation 2

Where:

x = larger number

y = smaller number

The simultaneous equations would be solved using the elimination method

Now, subtract  equation 2 from  equation 1

2y = 12

Divide both sides of the equation by 2

y = 12 / 2

y = 6

Substitute for y in  equation 2

x - 6 = 2

Add 6 to both sides of the  equation

x = 2 + 6

x = 8

The algebraic solution for the variable x is as follows:

The equation is represented as follows;

2 / 5 (2 - x) = - 1 / 3 x + 1 / 2

open the bracket on the left side

2 / 5 (2 - x) = - 1 / 3 x + 1 / 2

4 / 5  - 2x / 5 = - 1 / 3 x + 1 / 2

Add 1  /3 x to both sides

4 / 5  - 2x / 5 = - 1 / 3 x + 1 / 2

4 / 5  - 2x / 5 + 1 / 3 x  = - 1 / 3 x + 1 / 3 x  + 1 / 2

4 / 5 + 1 / 3 x - 2 / 5 x = 1 / 2

4 / 5 + 5x - 6x / 15 = 1 / 2

4  / 5  - x / 15 = 1 / 2

subtract 4 / 5 from both sides

4  / 5 - 4 / 5  - x / 15 = 1 / 2 - 4 / 5

- x / 15 = 5 - 8 / 10

- x / 15 = - 3 / 10

cross multiply

- x / 15 = - 3 / 10

-10x = - 45

divide both sides by -10

x = 45  /10

x = 9 / 2

Therefore, the algebraic solution for the variable x is 9 / 2.

The relation is not a function if its domain is on the x-axis and its range is on the y-axis. However, if the relation's domain is on the y-axis and its range is on the x-axis, it is a function.

If so, what kind of function is it?

Relationships are defined by three factors:

1. domain is a set of inputs.

2. an output set referred to as range.

3 . relationships between domain and range-related items.

If and only if each element of the domain is associated to just one member of the range, is a relation a function. It must be noted that the solution may vary based on the domain and range that we assume.

The provided relation is a function if the x-axis is the range and the y-axis is the domain, as opposed to when the x-axis is the domain and the y-axis is the range.

According to the question, the given parameters has relationship between the length and the width of the rectangle.

The perimeter of the rectangle is 18 inches.

Now, using standard perimeter as well as area formulas of a rectangle. Therefore, the equation can become:

Let us assume, the width of the rectangle be 'w' inches

The length of a rectangle be (9w - 11)

As we know, perimeter of a rectangle is 2(l + w)

Substitute the calculated parameters in the perimeter formula:

18 = 2(9w - 11 + w)

⇒ 9 + 11 =10w

⇒ w = 2 inches and l = 7 inches

Then, the calculated width is 2 inches and length is 7 inches.

Answer: -3b + 21

Step-by-step explanation:

-3(b-7) distribute the -3 to the rest of the equation

= -3b + 21

Answer:

Step-by-step explanation:

So we have our equation -3(b-7)

We are multiplying -3 by b, and by 7, and subtracting the products from each other

so, -3x7=-21

and we would have -3b

so now, we can put this back into the equation as

-3b+21 (because the rule is that subtracting a negative from a negative is the same as adding a positive)

The angled relationship is the Same-side interior angle where x is 6 and ∠EFG is 102°

For the parallel lines ED and FG, where EF is the transversal,

The angle DEF and the angle EFG are same-side interior angles.

By the same-side interior angle theorem, we can say that the interior angles on the same side of the transversal are supplementary (the sum of the angles is 180°).

∠DEF = 13x°

∠EFG = 17x°

∠DEF + ∠EFG = 180°

13x + 17x = 180

30x = 180

x = 6

∠DEF = 13x = 13*6 = 78°

∠EFG = 17x = 17*6 = 102°

Therefore, the angles follow the same-side interior angles relationship, x = 6 and ∠EFG = 102°
