Answer:

{-1, 0, 1, 3}

Step-by-step explanation:

A relation is a set of ordered pairs of numbers. The domain of a relation is the set of all the first elements (or x-values) in the ordered pairs. In this case, the relation is (-1,5) , (0,4), ( 1,2) , (3,-2), so the domain is the set of all the x-values in these ordered pairs, which is the set {-1, 0, 1, 3}. Therefore, the domain of the relation is {-1, 0, 1, 3}.

Answer:

bother = 6 years ; sister = 12 years

Step-by-step explanation:

s = sister

b = brother

s - b =  6

s * b = 4(s+b)

s = b + 6

b(b+6) = 4(b+6 + b)

b² + 6b = 4(2b + 6)

b² + 6b = 8b + 24

b² + 6b - 8b - 24 = 0

b² - 2b - 24 = 0

(b-6)(b+4) = 0

b = 6

b = -4 (impossible because an age can’t be negative)

s = 6 + 6

s = 12

Answer: The first job seems better.

Step-by-step explanation:

If 1 month = 4 weeks:

40 x 40 = 1600 per week

40 x 160 = 6400 per month

250 per week on gas

250 x 4 = 1000 per month on gas

1600 - 250 = 1350

6400 - 1000 = 5400

You would earn $1350 per week on the first job, and $5400 on this job.

_____________________________________________________

25 x 160 = 4000 per month

25 x 40 = 1000 per week

100 per week on gas

100 x 4 = 400 per month on gas

1000 - 100 = 900

4000 - 400 = 3600

$900 per week on the second job, and $3600 per month on this job.

Hello,

I hope you and your family are doing well!

To compare the two jobs and determine which one is more financially advantageous, you need to calculate the total income and total expenses for each job on a monthly basis.

For the first job, the total income is 40 dollars per hour * 160 hours per month = 6400 dollars per month. The total expenses are 250 dollars per week * 4 weeks per month = 1000 dollars per month. The net income is 6400 dollars per month - 1000 dollars per month = 5400 dollars per month.

For the second job, the total income is 25 dollars per hour * 160 hours per month = 4000 dollars per month. The total expenses are 100 dollars per week * 4 weeks per month = 400 dollars per month. The net income is 4000 dollars per month - 400 dollars per month = 3600 dollars per month.

Based on these calculations, the first job is more financially advantageous because it has a higher net income. You would earn an additional 1800 dollars per month by working the first job instead of the second job.

The probability for the experiment of drawing two marbles (without replacement) from a bag containing three green, three yellow, and four red marbles =  0.0111

In this question we need to find the probability for the experiment of drawing two marbles (without replacement) from a bag containing three green, three yellow, and four red marbles.

Total marbles in tha bag

= 3 green marbles + 3 yellow marbles + 4 red marbles

= 10 marbles

the probability of drawing one marble from a bag,

P1 = 1/10

Now there are 9 marbles in the bag.

So, the probability of drawing second marble would be,

P2 = 1/9

So, the required probability of drawing two marbles (without replacement) from a bag would be,

P = P1 * P2

P = 1/10 * 1/9

P = 1/90

P = 0.0111

Therefore, the probability of drawing two marbles (without replacement) from a bag = 0.0111

What is a number line?

In elementary mathematics, a number line is a picture of a graduated straight line that serves as visual representation of the real numbers.

In the given number line, the distance between point A and point B is 5.

Now we have to check each option

| 3 | + | -2 | = 3 + 2  = 5

| -2 + 3 | = | 1 | = 1

| -3 - 2 | = | -5 | =5

3 - ( -2 ) = 3+ 2 = 5

| 3 - ( -2 ) | = |3 + 2| = 5

Hence, the expressions that are equal to the distance between point A and point B would be

The area of rhombus is 100m²

What is rhombus ?

A rhombus is a quadrilateral with four equal-length sides in planar Euclidean geometry. The term "equilateral quadrilateral" refers to a quadrilateral whose sides all have equal lengths.

A parallelogram is a particular instance of a rhombus. The opposing sides and angles in a rhombus are parallel and equal. A rhombus also has equal-length sides on each side, and its diagonals meet at right angles to form its shape. The rhombus is also referred to as a diamond or rhombus.

A quadrilateral with four equal sides that has the shape of a diamond is called a rhombus. In everyday life, rhombus-shaped objects can be seen. In the illustration below, two instances of rhombuses in nature are shown: a diamond and a kite.

The area of rhombus is

The probability to get the numbers greater than 2 from the outcomes of  the event of rolling a single fair die is equal to P(A) = 2/3.

As given in the question,

Event is rolling a single fair die.

Number of fair die to be rolled = 1

Possible outcomes =  { 1, 2, 3, 4, 5, 6 }

Total number of possible outcomes = 6

Numbers greater than 2 on rolling a single fair die = { 3, 4. 5,6 }

Number of favourable outcomes = 4

Probability of getting a number greater than 2

= (Number of favourable outcomes) / (Total number of outcomes)

= 4 / 6

= 2 / 3

Therefore, the probability of getting a number greater than 2 while rolling a single fair die is equal to 2 / 3.

Triangles ABC and DEF might or might not be congruent since the angle-angle-angle (AAA) postulate is not a requirement for congruency of any two triangles. This is due to the fact that the angle-angle-angle postulate only takes into account the triangles' angles and does not specify their side lengths, hence congruency for these triangles may or may not be true.

What is a congruent triangle?

Therefore, if two triangles have the same number of sides on each side, they are said to be congruent.

                   Additionally, we can determine if they are congruent if we have a side, an angle between the sides, and then another side that is congruent, in that order: side, angle, side.

Step-by-step explanation:

If the amount borrowed at 7.5% is four times the amount borrowed at 8.5%. The amount borrowed is: $200,000, $800,000, $1,000,000.

Now let find the amount borrowed

Let X+Y+Z = 2000000

0.06X + 0.075Y + 0.085Z = 137000

Y = 4Z

Substituting Y=4Z into the first and second equations:

X + 5Z = 2000000

0.06X + 0.075(4Z) + 0.085Z = 137000

X = 2000000 - 5Z

0.06X + 0.385Z = 137000

0.06(2000000 - 5Z) + 0.385Z = 137000

120000 - 0.3Z +  0.385Z = 137000

0.085Z + 120000 = 137000

0.085Z = 17000

Divide both side by  0.085Z

Z= 17,000/0.085

Z = 200000

So,

Y = 4Z

Y = 800000

X= 200,000 + 800,000

X = 1000000

Hence,

Z = 200000

Y = 800000

X = 1000000

Therefore the amount borrowed is: $200,000, $800,000, $1,000,000.

The coordinates of the midpoint of line segment  A (-4,6) and B (2,-3) is M (-1 , 3/2).

A line segment is a measurable route between two points. Line segments can make up any polygon's sides because they have a set length.

Given:

Points A (-4,6), and B (2,-3)

Calculate the midpoint of the line segment by the formula given below,

[tex]M [(x_1 + x_2) / 2 \ \ , (y_1 + y_2)/2][/tex]

Substitute the values,

M [(-4 + 2) / 2 , (6 + (-3) / 2)]

M [(-2 / 2) , (3 / 2)]

M (-1 , 3/2)

The graph that correctly represents the function f(x) = [√(x + 3)] - 2 is; Graph D

We are given the function;

f(x) = [√(x + 3)] - 2

Remember that the argument of a square root must be zero or larger, then the minimum of the domain is the value of x such that:

x + 2 = 0

x = -2

Then the function starts at:

f(-2) = [√(-2 + 3)] - 2

f(-2) = 3

Then the graph should start at (-3, 2).

We can also identify another point by evaluating in x = 2.

f(2) = [√(2 + 3)] - 2

f(2) = -1
