Examples of a plane would be: a desktop, the chalkboard/whiteboard, a piece of paper, a TV screen, window, wall or a door. Examples of lines would be:

To solve such examples of we need to know about points, lines, and planes.

A Point can be described as an exact location in space but it has no size. A point is represented by a dot which shows the point in pictures and diagrams.

In the diagram, a line is represented by a capital letter with an arrow on the letters, such as [tex]\underset{AB}{\rightarrow}[/tex].

The examples of a point are a ball, a ball bearing, pin location on a map, etc.

A line is drawn when an infinite number of dots are connected together in both directions extended forever.

Examples of a line are a thread string, a wire, etc.

A plane is drawn when an Infinitely number of intersecting lines extend forever in all directions.

Answer:

x=2

Step-by-step explanation:

6x+2x-9=7

Combine like terms on each side of the equation

8x-9=7

Add 9 to each side

8x=16

Divide by 8 on each side

x=2

Simplifying

6x + -2x + -9 = 7

Reorder the terms:

-9 + 6x + -2x = 7

Combine like terms: 6x + -2x = 4x

-9 + 4x = 7

Solving

-9 + 4x = 7

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9' to each side of the equation.

-9 + 9 + 4x = 7 + 9

Combine like terms: -9 + 9 = 0

0 + 4x = 7 + 9

4x = 7 + 9

Combine like terms: 7 + 9 = 16

4x = 16

Divide each side by '4'.

x = 4

Simplifying

x = 4

Answer:

15 times for it to be equal, 15+ to be cheaper

Step-by-step explanation:

135+2x=11x

135=9x

135/9=x

15=x

135+2(15)=165$

11(15)=165$

Answer:

16 times

Step-by-step explanation:

Create an inequality where x represents the number of times he rents out the court:

2x + 135 < 11x

Solve for x:

135 < 9x

15 < x

So, Tom would have to rent the court out 16 times for it to be cheaper

When solving polynomial equations, first set the equation

equal to zero, then check for a Greatest Common Factor.

Since there is no greatest common factor, this will make life a

little bit more difficult because we will have to factor the trinomial.

First, find all possible factors for constant term.

I have listed these in red below.

Make sure to reverse the factors since in each binomial,

the first term is different so we need to reverse the factors.

The factors of 5x² will just be 5x and z.

After finding factors for the constant and the leading

coefficient for your trinomial, we can eliminate some factors.

If you have an odd coefficient on the middle term,

you can eliminate any pairs of even factors.

So the group I crossed out in purple below will be eliminated.

Another strategy is to use factors a little closer together.

So I would go with the 4 and 3 group.

Surely enough, our trinomial does factor with the 4 and 3.

Now set the factored trinomial equal to 0.

Then use zero product property and you have your answer.

Answer: [tex]\frac{8}{n^{3} }[/tex]

Step-by-step explanation:

 the quotient of 8  and the cube of a number is 8 divided by the number cubed  where n is the number.

Answer:

7) refer to d=rt triangle so answer is t= d/r

8) rearrange by dividing so it should be PV/nR = T

9) move 5r to  other side which become 2p = q - 5r then divide by 2. final answer is p = q-5r/2

10) multiply both side by b/1 so b got cancel on left side

right side become c(b/1) which is same as cb

then you divide both side by c to isolate b on the right side

final answer is a/c=b

Answer:

$28

Step-by-step explanation:

The towel was $44 but at 1/2 off would be $22.

Her total cost was $38 so we subtract $22 from $38 to find how much she paid for the beach hat.

$38-$22 = $16

We add $12 to $16 to find the original price of the hat.

$16+$12 = $28

Answer: y = 60x, choice D

=================================================

Explanation:

1 hour = 60 miles ... one way to represent the speed of 60 mph

x hours = 60x miles ... multiply both sides by x

After x hours, the cheetah has ran 60x miles. This is assuming the speed is kept the same at 60 mph.

The information about the 50 yards is never used. It's likely thrown in there as filler or as a distraction.

Answer:

I believe the answer is function

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Given that G is directly proportional to h then the equation relating them is

G = kh ← k is the constant of proportion

To find k use the condition h = 40 when G = 2200, then

2200 = 40k ( divide both sides by 40 )

55 = k

1

G = 55h ← equation of proportion

11

When h = 22, then

G = 55 × 22 = 1210 joules

111

When G = 3025, then

3025 = 55h ( divide both sides by 55 )

h = 55 m

Answer:

g(x) = x - 7

Step-by-step explanation:

g(x) is the same as saying "y".

you need to move the y-intercept down 7 units, therefore putting the term - 7 into the expression.

Answer:

g(x) = x-7

Step-by-step explanation:

First find f(x)

f(x) is the function  y =x

f(x) = x

g(x) = f(x) + C  C < 0 moves it down

We want to move it down 7 units

g(x) = f(x)  -7

g(x) = x-7

Answer:

  ∠CBD = 125°

Step-by-step explanation:

The angle sum theorem tells you that ...

  ∠ABC +∠CBD = ∠ABD

  8x -41° +9x +17° = 180° . . . . . . a "straight angle" has a measure of 180°

  17x -24° = 180° . . . simpify

  17x = 204° . . . . . . add 24°

  x = 12° . . . . . . . . . . divide by 17

Now the measures of the angles can be found from their expressions.

  ∠ABC = 8(12) -41° = 55°

  ∠CBD = 9(12) +17° = 125°

Comment on this math

This illustrates a shortcut for multiplying by 9 that can be convenient for mental arithmetic. The idea is to multiply by 10, which just involves adding 0 (or moving the decimal point), then subtract the original number.

Answer:

(-3,-2)

Step-by-step explanation:

Starting at the point (1, 0)

Now we move don 2 units (so the y-value reduces in two units) making now the point (1,0-2)  which is (1, -2)

then we move to the left 4 units (so the x-value has now to be decreased in 4 units) making the point: (1-4, -2) which is (-3, -2)

Answer:

It would be -2,4.

Step-by-step explanation:

you start at (1,0) and go down 2 to -2 then left 4 you would land on -2,4

Answer:

Yes, it's always positive

Answer:

Answer:

1) 46 cases to 1 min

2) 50 cans to 1 min

3) Cans are made faster

Step-by-step explanation:

1) 2 min per 92 cases so that's 2/2 and 92/2  which is 1 to 46

2) Now canned juice is as it shows in the graph as 50 cans per min.

3) 50 cans can be made in a min while only 46 cases can be made in a min.
