Answers

Answer 1

Answer:

D) m<1 = 50 m<7 = 130

Step-by-step explanation:

Lets set up the equation!

We know m<4 is 4x-30 and the m<5 is 2x + 50 due to alternate interior angles they are congruent so we can forge an equation, all we do is set them equal to each other!

4x-30 = 2x+50

Add 30 to both sides

4x = 2x +80

Subtract 2x from both sides.

2x = 80

Divide both sides by 2

x = 40

Now that we know x we can just plug it into the expression of m<4 to find m<1

4x-30

4(40)-30

80 - 30

50

m<4 = 50

Because m<1 and m<4 are vertical angles they are congruent!

m<1 = 50

We also know m<4 and m<5 are congruent so m<5 = 50 as well.

Because <7 is supplementary to <5 we know that the sum of both angles amount to 180.

x represents m<7

50 + x = 180

Now we solve by subtraction 50 from both sides

x = 130

m<7 = 130

please help me. solve for X

Answers

Answer:

1. x = 16

2. x = 17

Step-by-step explanation:

1. The sum of the exterior angles of any polygon is 360 degrees. So, to find x, we can add up all of the angle measures and set them equal to 360, then solve for x:

46 + 93 + 47 + 4x + 62 + 3x = 360

Combine like terms:

248 + 7x = 360

Subtract 248 from both sides of the equation to isolate 7x:

7x = 112

Divide both sides by 7 to find the value of x:

x = 16

2. The sum of the interior angles for a 5-sided polygon is 540 degrees. So, to find x, we can add up all of the angle measures and set them equal to 540, and then solve for x:

5x + 139 + 9x + 71 + 92 = 540

Combine like terms:

14x + 302 = 540

Subtract 302 from both sides to isolate the 14x:

14x = 238

Divide both sides by 14 to find the value of x:

x = 17

Transformation

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

If a point A(x, y) is rotated clockwise by 270 degrees, the new point is at A'(-y, x)

Quadrilateral PQRS is at P(-3, 5), Q(-1, 3), R(-3, 1) and S(-5, 3). If PQRS is rotated 270 degrees clockwise, the new point is at P'(-5, -3), Q'(-3, -1), R'(-1, -3) and S'(-3, 5)

Answers

Answer:

C. The value of a is the number that the x-values are multiplied by to get to the corresponding y-values. So, a = 3.

Step-by-step explanation:

Given the points (5, 15) and (-5, -15) are plotted using the equation y = a•x, this shows a proportional relationship between y and x.

Thus using any of the points, say (5, 15), x = 5, and y = 15, thus:

a = y/x = 15/5

a = 3

Therefore, the value of a, which is 3, is the number that the x-values, 5 and -5, are multiplied by to get the corresponding y-values, 15 and -15.

As we can see, if we multiply each of the x-values by 3, it will give us their corresponding y-values.

6. Second Solution

7. [tex]Area = 8.6016[/tex]

Step-by-step explanation:

Given

[tex]Length = 3x^2 + 5x - 8[/tex]

[tex]Width = 2x^2 + 6x[/tex]

Solving (1): The perimeter

Perimeter is calculated as thus:

[tex]Perimeter = 2 * (Length + Width)[/tex]

Substitute values for Length and Width

[tex]Perimeter = 2 * (3x^2 + 5x - 8 + 2x^2 + 6x)[/tex]

Open Bracket

[tex]Perimeter = 10x^2+ 22x - 16[/tex]

Solving (2): The Area:

Area is calculated as thus:

[tex]Area = Length * Width[/tex]

Substitute values for Length and Width

[tex]Area = (3x^2 + 5x - 8) * (2x^2 + 6x)[/tex]

Expand Bracket

[tex]Area = 2x^2(3x^2 + 5x - 8) + 6x(3x^2 + 5x - 8)[/tex]

Open Bracket

[tex]Area = 6x^4 + 10x^3 - 16x^2 + 18x^3 + 30x^2 - 48x[/tex]

Collect Like Terms

[tex]Area = 6x^4 + 10x^3 + 18x^3 - 16x^2 + 30x^2 - 48x[/tex]

[tex]Area = 6x^4 +28x^3 + 14x^2 - 48x[/tex]

Solving (3): If perimeter is 16, show that x = 1 and x = -3.2

In (a) [tex]Perimeter = 10x^2+ 22x - 16[/tex]

Substitute 16 for Perimeter

[tex]16 = 10x^2+ 22x - 16[/tex]

Equate to 0

[tex]10x^2+ 22x - 16 -16=0[/tex]

[tex]10x^2+ 22x - 32=0[/tex]

Expand

[tex]10x^2+ 32x -10x- 32=0[/tex]

Factorize

[tex]x(10x + 32) - 1(10x + 32) = 0[/tex]

[tex](x - 1)(10x + 32) = 0[/tex]

Split

[tex]x - 1 =0[/tex] or [tex]10x + 32 = 0[/tex]

[tex]x = 1[/tex] or [tex]10x = -32[/tex]

[tex]x = 1[/tex] or [tex]x = -32/10[/tex]

[tex]x = 1[/tex] or [tex]x = -3.2[/tex]

Solving (4): Using x = 1; Solve the dimension of the rectangle

We have that:

[tex]Length = 3x^2 + 5x - 8[/tex]

[tex]Width = 2x^2 + 6x[/tex]

Substitute 1 for x in the given parameters

[tex]Length = 3(1)^2 + 5(1) - 8[/tex]

[tex]Length = 3*1 + 5*1 - 8[/tex]

[tex]Length = 3 + 5 - 8[/tex]

[tex]Length = 0[/tex]

[tex]Width = 2(1)^2 + 6(1)[/tex]

[tex]Width = 2*1 + 6*1[/tex]

[tex]Width = 2 + 6[/tex]

[tex]Width = 8[/tex]

Solving (5): Using x = -3.2; Solve the dimension of the rectangle

We have that:

[tex]Length = 3x^2 + 5x - 8[/tex]

[tex]Width = 2x^2 + 6x[/tex]

Substitute -3.2 for x in the given parameters

[tex]Length = 3(-3.2)^2 + 5(-3.2) - 8[/tex]

[tex]Length = 3*10.24 + 5(-3.2) - 8[/tex]

[tex]Length = 30.72 -16 - 8[/tex]

[tex]Length = 6.72[/tex]

[tex]Width = 2(-3.2)^2 + 6(-3.2)[/tex]

[tex]Width = 2*10.24 + 6(-3.2)[/tex]

[tex]Width = 20.48 -19.2[/tex]

[tex]Width = 1.28[/tex]

[tex]Length = 6.72[/tex] and [tex]Width = 1.28[/tex]

Solving (6):

In the first solution of the dimensions in number 4, we have that

[tex]Length = 0[/tex] and [tex]Width = 8[/tex]

This dimension can not be considered because the length of a rectangle can not be 0

In the second solution of the dimensions in number 5, we have that

[tex]Length = 6.72[/tex] and [tex]Width = 1.28[/tex]

This dimension makes more sense because both dimensions are greater than 0

Solving (7): Using (6), determine the Area

In (6), we conclude that

[tex]Length = 6.72[/tex] and [tex]Width = 1.28[/tex]

So, Area is calculated as thus:

[tex]Area = Length * Width[/tex]

[tex]Area = 6.72 * 1.28[/tex]

[tex]Area = 8.6016[/tex]

Step-by-step explanation:

You use the information that is given and convert it into point-slope form y-y1=m(x-x1) like so. y-4= -5(x-5). Then you solve for y and you get y= -5x+29 which is slope intercept form (y=mx+b). Then you transform it into Standard form (ax+by=c) so all you do is add 5 on both sides and you get 5x+y=29. Now you have found your solution.

During his vacation, Dalyn rents a small boat from a rental service that charges a flat fee of $40 plus $20 per hour (including taxes).
The total charge comes to $120. Which equation can be used to calculate the number of hours, a, that Dalyn rents the boat?

Answers

Answer:

4 hours

Step-by-step explanation:

We can calculate this using the y=mx+c formula

y=total charge

m=per hour

x = (a) no. of hours

c= flat fee

y=20x+40

120=20x+40

We then solve like a normal equation

120-40=20x+40-40

80/20=20x/20

x=a

a=4

∴ Dalyn rents the boat for 4 hours

Answer:

25 + 8.50w ≥ 122

Step-by-step explanation:

Given that:

Amount saved per week = $8.50

Cost of phone = $122

Starting amount = $25

Minimum Number of whole weeks (w) Sébastien will need to save :

Starting amount + (weekly saving * number of weeks) ≥ 122

25 + 8.50w ≥ 122

8.50w ≥ 122 - 25

8.50w ≥ 97

w ≥ 97/8.50

w ≥ 11.4117

(3 points) (b) Solve the equation. Show all steps. (5 points) (c) Answer the question. How many consecutive games must she predict correctly to raise her percent to 65%? (1 point)

Answers

Answer:

[(6 + x) / 13+x] = 0.65

7

Step-by-step explanation:

Given that:

Total number of games = 13

Number of correct prediction = 6

Number of correct predictions needed to raise prediction % to 65%

(Number of correct predictions) / (total number of games) = 0.65

Let x = number of additional consecutive correct predictions

[(6 + x) / 13+x] = 0.65

Where x = number of consecutive predictions required

6 + x = (13 + x) * 0.65

6 + x = 8.45 + 0.65x

x - 0.65x = 8.45 - 6

0.35x = 2.45

x = 2.45 / 0.35

x = 7

x = £ 162.50

Money Ann received = 3x  = 3 *162.50 = £ 487.50

Money Ben received  = 7x   = 7 *162.50 = £ 1137.50

Money Cheryl received  = 10x  = 10* 162.50 = £ 1625

Total amount = 487.50 + 1137.50 + 1625 = £ 3250
