Answer:

C

Step-by-step explanation:

The table has 2 inputs that are the same (-1) but have different outputs (7 and 1). The list of coordinates also has 2 points with the same x - axis but different y values. For the graph you could use the vertical line test. If you put the line on -1 on the x-axis is goes through 2 points. The indicates that it is not a function.

Answer:

x/93/5 = 2/3

Multiplying both sides with 93/5

x = 2/3 * 93/5

x = 62/5 =12.4 feet tall

Step-by-step explanation:

9+11+|-1|

9+11+1

21

Answer: 21

Step-by-step explanation: the absolute value of any number will be positive so the absolute value of -1 is one. After that all you have to do it’s add 9 and 11 which is 20 + 1 which is 21

Answer:

The slope will be 2/5.

Step-by-step explanation:

[tex]y = 2/5x -1[/tex] is written in slope-intercept form.

This formula looks like:

[tex]y=mx+b[/tex]

where:

So:

1 ). For two lines to be parallel they must have the same slope.

2 ). For two line to be perpendicular they must have slopes that are opposite reciprocals.

As the question states, we must find the slope of a line parallel to the equation given. This means that the slope will remain 2/5.

Lets check our work!

Choose a random ordered pair. I will choose (5, 6).

Now, using point slope-form we can find out if what was said above is true!

This formula looks like:

[tex]y - y1 = m (x-x1)[/tex]

Let us substitute:

[tex]y - 6 = 2/5(x-5)[/tex]

Distribute:

[tex]y-6=2/5x-2[/tex]

Add 6 to both sides:

[tex]y= 2/5x+4[/tex]

Now using both equations I will plot them on a graph to see if they a parallel.

As you can see from the graph below, these lines are parallel. Where the equation you were given is in blue and the equation I made is in red.

Based on all of the evidence, the slope will be 2/5.

Answer:

We know the basic facts about parallelogram is The basic formula for calculating the area of a parallelogram is the length of one side times the height of the parallelogram to that side.

Step-by-step explanation:

The coordinates of the intersection of the diagonals  of parallelogram XYZW is at (6, 4).

A parallelogram is a quadrilateral in which opposite sides are parallel and equal. The diagonals of a parallelogram bisect each other.

Given parallelogram XYZW with vertices X(2, 2), Y(3, 6), Z(10, 6), and W(9,2).

The equation of diagonal XZ is:

The equation of diagonal YW is:

The point of intersection is at:

0.5x + 1 = (-2/3)x + 8

x = 6. Hence y = 4

The coordinates of the intersection of the diagonals  of parallelogram XYZW is at (6, 4).

Step-by-step explanation:

Each box of pens are valued at $1.50, thus for 2 boxers it would be 1.50 x 2 = $3. Thus, 2 boxes of pens = $3. Each box of pencils cost $1. therefore 3 boxes of pencils valued at $1 each = to $3. Final equation $3 + $3 = $6 for the first purchase. Using the same numbers we valued the 2 boxes of pencils at $1 each = $1 pencil box + $1 pencil box = $2 for 2 boxes. Then 4 pen boxes valued at $1.50 each = to $1.50 x 4 = $6 Final equation $6pen + $2pencil = $8 final

Step-by-step explanation:

Answer:

The value of x is 8

Step-by-step explanation:

In the given triangle

∵ A line segment joining points on two sides and parallel to the 3rd side

→ That means this line segment divided the two sides into equal ratios

∵ It divided the 1st side into 10 and 3x + 1

∵ It divided the 2nd side into 22 and 7x - 1

∴ [tex]\frac{10}{3x+1}[/tex] = [tex]\frac{22}{7x-1}[/tex]

→ By using cross multiplication

∵ 10(7x - 1) = 22(3x + 1)

∴ 10(7x) - 10(1) = 22(3x) + 22(1)

∴ 70x - 10 = 66x + 22

→ Subtract 66x from both sides

∵ 70x - 66x - 10 = 66x - 66x + 22

∴ 4x - 10 = 22

→ Add 10 to both sides

∴ 4x - 10 + 10 = 22 + 10

∴ 4x = 32

→ Divide both sides by 4

∴ x = 8

∴ The value of x is 8

Answer: Check below

Step-by-step explanation:

Okay so the Pythagorean Theorem was made by some old guy and the formula is a^2+b^2=c^2. You ALWAYS have to subtract the leg of the triangle when your finding a leg. You squareroot the square of the two legs if your finding the hypotnuse. The Theorem can be used to find any side of the triangle ONLY IF its a right triangle. An adult might use it in real life like when your an architect trying to find how much material you should use to make something thats in the shape of a right triangle.
