There are 7 possible positive integers that satisfy the inequality.

In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”. But to compare the values, whether it is less than or greater than, different inequalities are used.

We can find the positive values of x in the given inequality.

2x + 8 < 22

2x < 22 - 8

2x < 14

x < 7

The value of Y = 17.77 when X = 3, and the value of Y = 16 when X = 3

The equation which represents "Y varies inversely as the square of X"  can be written as:

Y = k/X² where "k" is a constant.

Substitute the values of  X=4 and Y= 10 in the variation equation and solve for k:

⇒ 10 = k/(4)²

⇒ 10 = k/16

⇒ k = 160

The variation equation :

⇒ Y = 160/X²

Substitute the values of X = 3 in the above equation and solve for Y:

⇒ Y = 160/(3)²

⇒ Y = 160/9

⇒ Y = 17.77

Thus, the value of Y = 17.77 when X = 3

The equation which represents "Y Varies inversely as X"  can be written as:

Y = k/X where "k" is a constant.

Substitute the values of Y=8 and X=6 in the variation equation and solve for k:

⇒ 8 = k/(6)

⇒ k = 48

The variation equation :

⇒ Y = 48/X

Substitute the values of X = 3 in the above equation and solve for Y:

⇒ Y = 48/(3)

⇒ Y = 16

Thus, the value of Y = 16 when X = 3

Answer:

X intercept: (-3/4 , 0)

Y intercept: (0 , 3/7)

Step-by-step explanation: The x intercept is a coordinate whenever y is 0. The y intercept is a coordinate whenever x is 0. So to find the x intercept you put 0 in place of Y and you solve for x. So you get x=-3/4.

You do the same thing to find Y, but you put 0 instead of x and you get y=3/7.

The coordinates of the point on the directed line segment that partitions the segment into a ratio of 5 to 3 are [-3.5, -2].

In this exercise, line ratio would be used to determine the coordinates of the point on the directed line segment that partitions the segment into a ratio of 5 to 3.

Mathematically, line ratio can be used to determine the coordinates of P and this is modeled by this mathematical expression:

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

Given the following parameters:

Substituting the given parameters into the line ratio formula, we have;

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

P(x, y) = [(5(-2) + 3(-6))/(5 + 3)],  [(5(-8) + 3(8))/(5 + 3)]

P(x, y) = [(-10 + (-18))/(5 + 3)],  [(-40 + 3(8))/(5 + 3)]

P(x, y) = [(-10 - 18)/(8)],  [(-40 + 24)/(8)]

P(x, y) = [(-28)/(8)],  [(-16)/(8)]

P(x, y) = [-3.5, -2]

The equation of the graphed line is written as: y = 2x + 2.

The equation of a graphed line can be determined by calculating the slope of the line, m = rise/run, and determining the y-intercept value, b, which is the point at which the line intersects the y-axis.

Using two points on the graphed line in the diagram attached below, (-4, -6) and (2, 6):

Slope (m) = change in y / change in x = (-6 - 6) /(-4 - 2)

Slope (m) = -12/-6

Slope (m) = 2

The line cuts the y-axis at y = 2. The y-intercept of the line, b = 2.

Both the length and width of the rectangle are approximately 31.62 m each.

The Area of a rectangle is calculated by multiplying the length by the width.

A = L x W

We have given that area of rectangle is 1,000 m²

1000 = W× L => W = 1000/L ---(1)

The circumference of rectangle is twice the sum of the dimensions. That is,

P = 2L + 2(1000/L)

Now, it is provided that perimeter is minimum so, we differentiate perimeter with respect to L then put first order derivative equal to zero.

dP/dL = 2 + 2000(-1/L²) = 0

=> 2-2000/L²=0

=>2000/L²=2

=> L²=2000/2

=> L²= 1000

=> L= 31.622

putting value of L in (1) we get , W= 31.622m

Therefore the length and width of the rectangle are both approximately 31.622m .

The system of equations for determining the dollar amount of  phone and computer sales are Sc = Sp + 600 and 0.05Sc + 0.04Sp = 1200

A commission is defined as the compensation paid to a person or entity based on the sale of a product. It is calculated on a percentage basis

Given:

Phone sales commission = 4%

Computer sales commission = 5%

Total commission = $129

Let Sc and Sp represent the dollar amount of phone sales and computer sales respectively

If Houa had $600 more in computer sales than in phone sales, the equation can be written as:

Sc = Sp + 600

Since Houa earns a 4% commission on phone sales and a 5% commission on computer sales, and a total commission of $129. Thus, the equation for the commission can be written as:

0.05Sc + 0.04Sp = 1200

Note:  5% = 5/100 = 0.05 and  4% = 4/100 = 0.04

Answer:

Co-interior angles or Consecutive interior angles are the two angles that are on the same side of the transversal. Co-interior angles are the interior angles and it sums up to 180 degrees. It means that the sum of two interior angles, which are on the same side of transversal is supplementary. Co-interior angles resemble like in “C” shape and both the angles are not equal to each other. The co-interior angle is also known as the consecutive interior angles or the same side interior angles.Co-interior Angles

Co-interior Angle Theorem and Proof

Statement:

If the transversal intersects the two parallel lines, each pair of co-interior angles sums up to 180 degrees (supplementary angles).

Proof:

Co-interior Angles Proof

Let us consider the image given above:

In the figure, angles 3 and 5 are the co interior angles and angles 4 and 6 are the co-interior angles.

To prove: ∠3 and ∠5 are supplementary and ∠4 and ∠6 are supplementary.

Given that, a and b are parallel to each other and t is the transversal.

By the definition of linear pair,

∠1 and ∠3 form the linear pair.

Similarly, ∠2 and ∠4 form the linear pair.

By using the supplement postulate,

∠1 and ∠3 are supplementary

(i.e.) ∠1 + ∠3 = 180

Similarly,

∠2 and ∠4 are supplementary

(i.e.) ∠2 + ∠4 = 180

By using the corresponding angles theorem, we can write

∠1 ≅∠5 and ∠2 ≅ ∠6

Thus, by using the substitution property, we can say,

∠3 and ∠5 are supplementary and ∠4 and ∠6 are supplementary.

Hence, the co-interior angle theorem (consecutive interior angle) is proved.

The converse of this theorem is “if a transversal intersects two lines, such that the pair of co-interior angles are supplementary, then the two lines are parallel”.
