Consider the two graphs above.

Which statement best describes the graphs?

A. Graph 1 represents a proportional relationship, but graph 2 does not.

B. Graph 2 represents a proportional relationship, but graph 1 does not.

C. Both graph 1 and graph 2 represent proportional relationships.

D. Neither graph 1 nor graph 2 represent a proportional relationship.

Answers

Answer 1

Answer:

B. Graph 2 represents a proportional relationship, but graph 1 does not.

Step-by-step explanation:

All proportional relationships pass through the origin. Graph 2 does but Graph 1 does not. Additionaly, Graph 2 is a straight line that represents a proportional relationship. Another way to find out if it is proportional is to find the constant of proportionality by dividing the y by the x in different parts of the line. The numbers should all have the same constant of proportionality.

Examples (all found in Graph 2):

15/3 = 5

10/2 = 5

5/1 = 5

Answer 2

B, Graph 2 represents a proportional relationship, but graph 1 does not

Sorry if I’m work

Write the equation in slope-intercept form and then graph the equation that passes through (3, 2) and is parallel to the x-axis

Answers

Answer:

y = 2

Step-by-step explanation:

The line is parallel to x-axis so its slope = 0

in y = mx + b:

m = 0

b is the y intercept so b = 2 ( from the graph)

y = 0×x + 2

y = 2

the length of a rectangle is 5 more than twice the width. if the perimeter of the rectangle is 76 meters, find the dimensions of the rectangle and choose the equation that represents the perimeter:

1. 76=2w+5
2. 76=2w+2(2w+5)
3. 76=w+2w+5
4. 76=2w+(2w+5)

Answers

Answer:

Dimensions: 11 meters by 27 meters

2. [tex]76=2w+2(2w+5)[/tex]

Step-by-step explanation:

Finding Dimensions:

The perimeter of a rectangle can be written as [tex]2l+2w[/tex] where [tex]l[/tex] is the length and [tex]w[/tex] is the width. It is given that the length is 5 more than twice the length of width and the perimeter of the rectangle is 76 meters.

With this information we can write:

Length = [tex]2w+5[/tex]

[tex]2(2w+5)+2w = 76[/tex] (perimeter of the rectangle)

[tex]4w+10+2w=76[/tex]

[tex]6w=66[/tex]

[tex]w=11[/tex]

Length = [tex]2(11)+5[/tex]

Length = [tex]27[/tex]

∴ The dimensions of the rectangle is 11 meters by 27 meters.

Perimeter

Since the length can be written as [tex]2w+5[/tex], the equation that represents the perimeter of the rectangle is [tex]76=2w+2(2w+5)[/tex]

If two sides and the angle that is not between them of one triangle are congruent to the corresponding two sides and the angle that is not between them of another triangle, then the congruency of those triangles cannot be determined.

Answers

Answer:

True

Step-by-step explanation:

The given parameters are;

Two triangles each with known measures of two sides of the triangle and a non included angle

Therefore, with the given information, each of the the triangles are undefined because the sides can be opened wider or narrowed to have two possible solutions, in the same manner a compass, having one leg at a fixed inclination to the drawing paper can have the second leg either come closer or go further than 90 degrees while the inclination of the one (first) leg remains the same.

Sin = opposite/hypotenuse

Cosine = adjacent/hypotenuse

Tangent = opposite/adjacent

We have to find cos(x) = adjacent/hypotenuse

[tex]cos(x) = adj/hyp\\=\frac{24}{26} = \frac{12}{13}[/tex]

#2:

We are given an angle of 30 degrees and an opposite side of 15

We need to find the adjacent side, so we can use Tangent

[tex]tan(30) = \frac{15}{adj}[/tex]

[tex]adj = \frac{15}{tan(30)} = 25.98 = 26[/tex]

We are given an angle and an opposite side and we have to solve for hypotenuse.

We can use sin

[tex]sin(43) = \frac{16}{x} \\x = \frac{16}{sin(43)} = 23.46 = 23.5[/tex]

#4:

We are given two sides, we have to find the angle. We are given an opposite side and an adjacent side, so we can use arctangent ([tex]tan^-1(x)[/tex], but not 1/tan(x))

[tex]tan(x) = \frac{36}{19} \\arctan(36/19) = x\\x = 62.1759[/tex]

We are given an opposite side and the hypotenuse, we can use sin

[tex]sin(x) = \frac{19}{28}\\x = arcsin(19/28) = 42.73 = 43[/tex]

x = 14

m<U = 9(14) -6

m<U = 126 - 6

m<U = 120 degrees

Answer:

120

Step-by-step explanation:

U = W

(9x-6) = (7x+22)

SOLVE

subtract 7x from each side.

2x-6 = 22

add 6

2x = 28

divide by 2

x = 14

plug 14 into x and solve.

9(14)-6 = 120

7(14)+22 = 120

both angles are the same

Answers

Answer: (6.75,0)

Step-by-step explanation:

The x-intercept of a line is when it's y coordinate is 0, so input 0 into the equation for y and solve for x.

4x + 9(0) = 27

4x = 27

x= 6.75

I think the x intercept would be 27/4. This is the best way i can explain.

Answers

Answer:

1.)13x = +9

2.)9x = -5

so first you take 1^2 power and it would be 1 so then u add the 1x on to the 12x or 8x from whatever equation ur working on and u would get 13 x or 9x from there u need to get the x isolated from the number without an x so if ur doing number 1 you would do +9 on both sides which would clear the -9 on the left side and add 9 on the right making it 13x = 9
