Answer:

y = [tex]\frac{1}{4}[/tex] x - 2

Step-by-step explanation:

y = mx + b is slope-intercept form of linear equation.

Solve x - 4y = 8 for "y"

- 4y = - x + 8

y = [tex]\frac{1}{4}[/tex] x - 2

Answer:

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

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

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

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

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

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]

Collect Like Terms

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

[tex]Perimeter = 2 * (5x^2+ 11x - 8 )[/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]

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

7 consecutive correct predictions

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

97/8.50 <

11.4 --> 12

x < 12

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

Answer:

y=2x+5

Step-by-step explanation:

Answer:

5x+y=29

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.

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

The rule that describes this transformation is R₀ 270°

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)

Answer:

The figure will result is cone ⇒ B

Step-by-step explanation:

When a right triangle is rotated about its vertical leg 360°, then it formed a cone its radius is the horizontal leg of the triangle and its height is the vertical lege of the triangle

In the given figure

∵ Triangle TRE is a right triangle

∴ The horizontal leg is RE

∴ The vertical leg is TR

∵ The triangle is rotated around the horizontal leg RE 360°

∴ It formed a cone its radius = TR and its height = RE

∴ The figure will result is the cone

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.

Answer:

Total amount  = £ 3250

Step-by-step explanation:

Ann : Ben : Cheryl = 3 : 7 : 10

Money Ann received = 3x

Money Ben received  = 7x

Money Cheryl received  = 10x

Ben received £650 more than Ann.

7x - 3x = 650

     4x = 650

       x = 650/4

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

Step-by-step explanation:

If A=650+135N; and B=585N,

then A+B= 650+135N+585N=650+620N

T=720N+650

A function assigns values to each element. An equation relating T to N can be represented by T=650+720N.

A function assigns the value of each element of one set to the other specific element of another set.

The function which tells the amount that is been saved by Jina is given by the function A=650+135N, while the function which tells the amount that will be saved by her husband is B=585N.

Since the total saving amount is represented by T which is the sum of the two functions A and B. Therefore, the function of T can be written as,

[tex]\rm T=A+B\\\\T = (650+135N)+585N\\\\T = 650+135N+585N\\\\T = 650+720N[/tex]

Thus, an equation relating T to N can be represented by T=650+720N.
