Answer:y=14x+7

Step-by-step explanation:

Answer:

You're right, it is 359!

Let's break down the problem.

The equation is...

21 - 359 / 26 = 13

Therefore,

The missing number, n, is 359.

Answer:

x = 1

Step-by-step explanation:

2x +4 (3 - 2x) = 3(2x + 2)/6 + 4

2x+12-8x = (6x+6)/6 +4

-6x + 12 = x+1+4

12-5 = 7x

7x = 7

x=1

Hope this helps!

2x + 4(3-2x) = 3(2x+2)/6 +4

Break the brackets :

2x + 12 - 8x = (6x+6)/6 + 4

2x + 12 - 8x = x + 5

2x + 12 - 8x - (x+5) = 0
2x + 12 - 8x - x - 5 = 0
-7x + 7 = 0

-7x = -7
x = 1.

The area of Jill's soccer net is 3 times larger than area of Peter's soccer net.

The area of Peter's soccer net is determined by using area of rectangle as shown below;

A1 = 5.5 ft x 4 ft

A1 = 22 ft²

A2 = 5.5 ft x 12 ft

A2 = 66 ft²

A2/A1 = 66/22

A2/A1 = 3

Thus, the area of Jill's soccer net is 3 times larger than area of Peter's soccer net.

Answer:

√3

Step-by-step explanation:

From the formula used in calculating Friction, we have:

Frictional Force = coefficient of Friction × Reaction

i.e Fr = μ × R

Resolving Frictional Force and Reaction of a body moving with on an Inclined plane,

Frictional Force = mass × g × sin a

where a = to the angle given

Reaction = mass × g × cos a

Therefore,

mass × g × sin a = μ × mass × g × cos a

mass and g cancels out on both sides.

Therefore,

sin a = μ × cos a

make "μ" subject.

μ = sin a/cos a

(recall: tan a = sin a /cos a)

μ = tan a

recall a = angle given = 60°

μ = tan 60°

μ = √3

or simply recall that

μ = tan a

μ = tan 60°

μ = √3

The height of the ceiling is 162.31 meters

The situation will form a right angle triangle.

Right triangle has one of its angles as 90 degree. Therefore, the sides can be found using trigonometric ratios

The triangle formed, the theodolite distance from the spotlight is the  adjacent side. Therefore,

tan 62.7 = opposite / adjacent

tan 62.7 = x / 83

cross multiply

x = 83 × tan 62.7

x = 160.809554025 m

Therefore, the height of the ceiling form the ground is as follows:

[tex](x-5)(x-5)[/tex]

Step-by-step explanation:

We need to find two numbers that multiply to get 25 and have a sum of -10...

(-5)(-5)=25

-5-5=-10

We can split -10x into -5x and -5x:

[tex]x^2-5x-5x+25[/tex]

Factor each half of the expression separately:

[tex]x(x-5)-5(x-5)[/tex]

Since both x and -5 are being multiplied by (x-5), we can combine them to get:

[tex](x-5)(x-5)[/tex]

All the faces are the same and 8 vertices would make a cube.

Answer: cube

All of its faces are congruent, it has 8 vertices and it is a 3D figure, so it is a cube.

A cube is a three-dimensional geometric shape that meets the given criteria.

Let's break down the reasons why:

This means that each face has the same shape and size, and all angles within the cube are right angles (90 degrees).

Each vertex is the point where three edges of the cube meet.

It has length, width, and height, making it a 3D geometric figure.

A cube is a special type of rectangular prism where all sides are equal in length.

Its symmetry and regularity in terms of congruent faces, edges, and vertices make it a fundamental and easily recognizable three-dimensional shape.

Step-by-step explanation:

n² - 16 ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b) , then

n² - 16

= n² - 4²

= (n + 4)(n - 4)

cannot be (n + 8)(n - 8)

Answer:

10 hours

Step-by-step explanation:

1. Create a chart.

miles    -  hours

7.5.       -   0.5 (30 minutes = 0.5 hours)

150.      -    x (let's use a variable to represent number of hours Jimmy ran)

2. Cross multiply:

7.5(x) = 150(0.5)

7.5x. = 75

3. To isolate x, divide both sides of equation by 7.5

7.5x/7.5 = 75/7.5

4. 7.5 crosses out with itself on the left side of the equation.

5. 75/7.5 = 10

x = 10

Therefore, Jimmy ran 150 miles in ten hours.

Step-by-step explanation:

Answer:

length = 15

Width = 9

Step-by-step explanation:

In a rectangle opposite sides are equal.

5x - y- 8 =3x +5y + 4

5x - 3x  -y - 5y = 4 + 8

2x - 6y = 12

Divide the entire equation by 2

x  - 3y = 6  --------------(I)

3x + y - 4 = 2x - 6y - 3

3x - 2x + y + 6y = -3 + 4

x + 7y = 1 -------------(II)

Multiply equation (II) by (-1)

(I)            x - 3y = 6

(II)*(-1)    -x - 7y = -1   {Now add. 'x' will be eliminated}

                  -10y= 5

                      y = 5/(-10)

                     y = -0.5

Plugin y = -0.5 in equation (I)

x - 3*(-0.5) = 6

x  + 1.5 = 6

        x = 6 - 1.5

        x = 4.5

Length = 5x - y - 8

           = 5*4.5 - (-0.5) - 8

           = 22.5 + 0.5 - 8

            = 23 - 8

Length = 15

Width = 2x - 6y - 3

         = 2*4.5 - 6*(-0.5) - 3

         =  9 + 3 - 3

Width = 9

Step-by-step explanation:

The starting point for an e=inequality will have either an empty of filled-in circle.  When empty, it signifies that the exact point is NOT included.  If the inequality is x < 2, for example, the line would begin at 2, but marked with an empty circle.  If, however, the inequality is x =< 2, then the circle is filled in, signifying that the number 2 is included in the set.

Answer: The slope is undefined.

Step-by-step explanation:

The slope of a line is (y2-y1)/(x2-x1) given two points (x1,y1) and (x2,y2).

We can plug in the coordinates given.

= (-3-2)/(-1-(-1))

= -5/0

That value is undefined beacuse you cannot divide a value by 0.
