Step-by-step explanation:

In the following ways we can break up the real numbers into the two disjoint subsets.

According to the given question.

We have to break the set of real numbers into two disjoint sets.

As we know that, two sets are said to be disjoint sets if they have no elements in common.

Therefore, in the following ways we can break up the real numbers into the two disjoint subsets.

The set of real numbers equal to zero and the set of other real numbers.

The set of natural numbers greater than 50 and the others. The set of real numbers whose absolute value is less than one, and the others. The set of real numbers whose square is less than 25 and others.

Answer:

(a)  3.5

(b)  x = 4

(c)  -¹/₂

(d)  -¹/₂

Step-by-step explanation:

f(1) is the value of y when x = 1.

To find the value of y from a given value of x, find the position of x on the x-axis, then trace vertically until you meet the line. Once you meet the line, trace horizontally to the y-axis to find the corresponding value of y.

Therefore, f(1) = 3.5.

To solve f(x) = 2, find the value of x when y = 2.

To find the value of x from a given value of y, find the position of y on the y-axis, then trace horizontally until you meet the line. Once you meet the line, trace vertically to the x-axis to find the corresponding value of x.

Therefore, the solution of f(x) = 2 is x = 4.

The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:

[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]

Given interval:  2 ≤ x ≤ 4

Therefore:

[tex]\implies \dfrac{f(4)-f(2)}{4-2}=\dfrac{2-3}{4-2}=-\dfrac{1}{2}[/tex]

The average rate of change between any interval of the given function will be the same as the graph is linear.  Therefore, the average rate of change from 0 to 8 is the same as the rate found in part (c):  -¹/₂.

Proof

The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:

[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]

Given interval:  0 ≤ x ≤ 8

Therefore:

[tex]\implies \dfrac{f(8)-f(0)}{8-0}=\dfrac{0-4}{8-0}=-\dfrac{4}{8}=-\dfrac{1}{2}[/tex]

Considering point Q (x, y) to be (1, 2), and translating it by (x-3, y+4), the image of point Q, say Q' will be positioned at (-2, 6), which is plotted in the reference image attached hereby.

As per the question statement, we are required to plot the image of point Q(x, y) under the translation (x-3, y+4).

Let us assume the point Q to be (1, 2). Therefore, a translation of (x-3, y+4) on (1 , 2) will result in a new position, which will be:

3 units to the left of (1, 2) along the x-axis, and then 4 units upwards along y-axis.

Hence, the position of the image of Q (1, 2) after a translation of (x-3, y+4) will be Q' [tex][(1-3), (2+4)]=(-2, 6)[/tex].

Both the points Q(1, 2) and its image after the translation of (x-3, y+4), Q'(-2, 6) are plotted in two separate graphs, attached hereby for reference.

Tom and Ben received 650 and 780 respectively.

Let the amount paid to each for every hour they work be x. Now, forming the equation as per the given information in question.

5x + 6x = 1430

Performing addition to find the value of x.

11x = 1430

Shifting 11 to Right Hand Side of the equation

x = 1430 ÷ 11

Performing division to find the value of x

x = 130

Now finding the amount received by Tom and Ben based on the number of hours they worked.

Amount received by Tom = 5x

Amount received by Tom = 5 × 130

Amount received by Tom = 650

Amount received by Ben = 6x

Amount received by Ben = 6 × 130

Amount received by Ben = 780

Therefore, the amount received by Tom and Ben are 650 and 780 respectively.

Answer:

"Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628," said Gobets. He developed a symbol for zero: a dot underneath numbers.

Keiko used 83.5 pounds of type A coffee and 82.5 pounds of type B coffee in the blend.

An expression constructed using integer constants, variables, and algebraic operations is known as an algebraic expression

Given:

Type A coffee cost $5.35 per pound

Type B Coffee cost $4.05 per pound

Keiko made total 166 pound of the blend of $780.85

Therefore,

[tex]5.35x + 4.05y = 780.85 \;\;\;\;\; -------equation (1)[/tex]

[tex]x + y = 166 \;\;\;\; ---------equation (2)[/tex]

simplify the equation (2),

[tex]y = 166-x[/tex]

Substitute the value of y in equation (1),

[tex]5.35x + 4.05 (166-x) = 780.85[/tex]

[tex]5.35x + 672.3 - 4.05x = 780.85[/tex]

[tex]5.35x-4.05x=780.85-672.3[/tex]

[tex]1.3x=108.55[/tex]

Therefore,

Answer:

13, 15,17

Step-by-step explanation:

Let x = the first number

Let x + 2 = the second number

Let x + 4 = the third number

Consecutive means in order like 1,2,3 or 20,21,22. Consecutive odd means that you want three numbers in order that are odd.  Each number would be 2 more than the number before.  For example 5 + 2 = 7.  We would have to add 4 to 5 to find the next consecutive odd number.

x + (x + 2) + (x +4)  = 45  I put the numbers in parentheses so you could see the first number plus the second number plus the third number equals 45

x + x+ 2 + x+ 4 = 45  Combine like terms

3x + 6 = 45  Subtract 6 from both sides of the equation.

3x = 39  Divide both sides by 3

x = 13

Add 2 to that to get the next odd number.

Add 4 to 13 to get the third odd number.

John received $112.5 and Joan received $157.5 respectively as per the given ratio.

John and Joan share the amount in the ratio: 5:7

it is given that Joan had $45 more amount than John, therefore

Let the amount with John be x, so the amount with Joan will be x + 45

Formulating the equation we get:

Amount with John/Amount with Joan = Ratio of money with John/Ratio of money with Joan

x/(x + 45) = 5/7

7x = 5x + 225

2x = 225

x = 112.5

Amount with John  = 112.5

Amount with Joan = 157.5

Answer:

y=3x-8

Step-by-step explanation:

Slope -intercept form is y=mx+b.

M represents the slope; b represents the y-intercept.

First, let's find the y-intercept.

It'll be found on the y-axis on the graph.

If you go down the y-axis, you'll see that -8 is the only point to be directly on the y-axis, so we can assume that that's the y-intercept.

Thus, the B in the equation is -8.

Now, let's find the slope.

You can think of it as rise over run. The rise is how many numbers the y-intercept either goes up or down until it can cross over to the x-axis. Crossing sideways is the run that's located on the x-axis.

You can begin from -8 and either count downward or upward.

For the sake of this graph, we'll go upward.

Do you see the dot on the coordinate (1,-5)?

Count upward and go to the side to get to that coordinate.

I count three upward and one to the right.

So as a fraction that would be 3 over 1 or 3/1.

But you can simplify that to just 3.

Thus, the M in the equation is 3.

Hence, y=3x-8.
