Answer:

The polynomials are:

[tex]\frac{2}{3}[/tex] x² + x + 1 ⇒ C

x³ + 2x +√2 ⇒ E

Step-by-step explanation:

A polynomial: is an expression consisting of variables and coefficients, with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables

Let us solve the question

∵ The polynomial never division by a variable

∵ Answer A and B have a division in variable ⇒ ( [tex]\frac{1}{x^{2}+1 }[/tex] , [tex]\frac{2}{x^{3}}[/tex] )

∴ Answers A and B are not polynomials

∵ The polynomial has integer exponents of variables

∵ Answer D has a fraction exponent of x ⇒ [tex]x^{\frac{2}{3}}[/tex]

∴ Answer D is not a polynomial

∵  [tex]\frac{2}{3}[/tex] x² + x + 1 has a non-negative integer exponent of x

∵ There is no division by x

∴  [tex]\frac{2}{3}[/tex] x² + x + 1 is a polynomial

∵ x³ + 2x +√2 has a non-negative integer exponent of x

∵ There is no division by x

∴ x³ + 2x +√2 is a polynomial

∴ The polynomials are [tex]\frac{2}{3}[/tex] x² + x + 1 and x³ + 2x +√2

Answer:

Step-by-step explanation:

The answer is 10 because 7 + 3 equals 10!

This can be proven by adding 7 + 3 or by subtracting in a certain way.

7 + 3 = ?

7 + 1 = 8

7 + 2 = 9

7 + 3 = 10

You can show more work by subtracting your answer or 10 in this case, which means that you subtract 7 by 10 or 3 by 10, either way is ok.

If you subtract 7 by 10, ( 10 - 7 ) then you get 3

If you subtract 3 by 10, ( 10 - 3 ) then you get 7

If the number you subtracted matches the number that you didn't subtract, then your answer is correct.

Answer:

The constant of variation is 2

Step-by-step explanation:

The equation of the direct variation is y = k x, where k is the constant of variation

Let us solve the question

∵ x and y are in the direct variation

→ Use the form of the equation above

∴ The equation of variation is y = k x

∵ x = 3

∵ y = 6

→ Substitute them in the equation above

∴ 6 = k (3)

∴ 6 = 3k

→ To find k divide both sides by 3

∵ [tex]\frac{6}{3}[/tex] = [tex]\frac{3k}{3}[/tex]

∴ 2 = k

∵ k is the constant of variation

∴ The constant of variation is 2

Answer:

y > 2x - 1

y ≤ 0.5x + 4

Step-by-step explanation:

solid line: (0,4) (-8,0)

m: (0-4)/(-8-0) = -4/-8 = 0.5

b: 4

y = mx + b       y = 0.5x + 4

dotted line: (0,-1) (-2,-5)

m = (-5 - -1)/(-2-0) = 2

b = -1

equation: y = 2x - 1

System: y ≤ 0.5x + 4

             y > 2x - 1

Answer:

2pi/3 radians

Step-by-step explanation:

In the following way we can get the answer:

The measure of m∠POQ is (2/3)π radians.

A circle is a two-dimensional figure with a radius and circumference of 2πr.

we have,

Triangle POQ is an isosceles triangle.

PO = OQ

Sin P = 3/6

Sin P = 1/2

Sin P = Sin 30°

P = 30

m∠P = m∠Q = 30°

m∠P + m∠Q + m∠O = 180

30 + 30 + m∠Q = 180

m∠Q = 180 - 60

m∠Q = 120°

180° = π

120° = π x (120/180)

120° = (2/3)π radian.

Thus,

The measure of m∠POQ is (2/3)π radians.

Answer:

n[tex]\leq[/tex]6

Step-by-step explanation:

4n[tex]\leq[/tex]21+3

4n[tex]\leq[/tex]24

n[tex]\leq[/tex]24/6

Answer:

n ≤ 6

Step-by-step explanation:

first you'd add 3 to both sides to get 4n by itself. addition cancels subtraction. remember whatever you do to one side, you must do to the other

4n ≤ 24

then you must divide by 4, to cancel out the multiplication to get n by itself.

n ≤ 6

so anything less than 6 or equal to 6 will make the inequality true

Answer:

  see below for a graph

Step-by-step explanation:

Your equation has "y alone". It is written in "slope-intercept form."

  y = mx + b . . . . . . . where m is the slope and b is the y-intercept.

Comparing your given equation ...

  y = 1/2x + 18

to the above form you see that m = 1/2 (the slope) and b = 18 (the y-intercept).

The y-intercept is where the graph crosses the y-axis, so the first point you can plot on the graph is at (0, 18) on the y-axis.

The slope of 1/2 tells you the ratio of "rise" to "run" is 1/2. That is, the "run" (change in x) is 2 units for each "rise" (change in y) of 1 units

  m = rise/run = 1/2

So, another point (or several) can be found by moving twice as many units to the right as you move up. For example, if you choose 10 units right, to x=10, the point will be 10/2 = 5 units up from y=18, at y = 23. That is (10, 23) is another point on the graph.

Now, you have points (0, 18) and (10, 23) on the line. The graph will be a straight line through those points.

Answer:  $80,735

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

Work Shown:

33% = 33/100 = 0.33

33% of 120,500 = 0.33*(120,500) = 39,765

Michael pays $39,765 in taxes

This makes his net pay to be 120,500-39,765 = 80,735 dollars.

------------

A shortcut is to compute

0.67*(120,500) = 80,735

The 0.67 refers to the fact that if he pays 33% of his gross income, then he keeps the remaining 100% - 33% = 67% of it.
