Answer:

It is the 3rd option. If it doesn't have a line below it, the circle should be open. And where the arrow points is where your line should go if that makes sense.

Answer:

C. JK and LM are congruent

Step-by-step explanation:

Given the coordinates J(-2,8), K(0,8), L(1,0), and M(1,-2), in other to determine whether JK is congruent to LM, we need to determine if the length of side JK and LM are equal i.e JK = LM

To get JK:

We will find the distance between the coordinates J(-2,8), K(0,8) to get the length JK using the formula:

JK =√(x2-x1)²+(y2-y1)²

JK = √(0-(-2))²+(8-8)²

JK = √2²+0²

JK = √4

JK = 2

For the length of LM with coordinate L(1,0), and M(1,-2)

LM = √(1-1)²+(-2-0)²

LM = √0²+(-2)²

LM = √0²+2²

LM = √0+4

LM =√4

LM = 2

Since JK = LM = 2 units, this means that JK and LM are congruent.

Answer:

$54

Step-by-step explanation:

The original price was $90

The sale of the parrot is 40% off

40% * $90 = $36

The sale price = $90 - $36 = $54

Hence, the sale price of the parrot = $54

Answer:

x = 20

Step-by-step explanation:

Let's look at the first parallel lines (the ones with one arrow).

Because both these lines are parallel, we can say that (3x + 2) and (4x - 18) are equal due to the alternate interior angles theorem.

So we have to make both of these expression equal to each other, and then solve:

3x + 2 = 4x - 18

-x = - 20

x = 20            < --- this is your answer

Hope this helps!

Answer:

If simplifying, then

x^3 -13x^2 -x -49

Step-by-step explanation:

To do this, I would start off with the left side (use PEMDAS)

Use FOIL (First, Outside, Inside, Last)

x^3 + -9x^2 + 6x + -54 - (4x^2 + 7x - 5)

Bring negatives inside parenthesis

x^3 -9x^2 +6x -54 -4x^2 -7x +5

Combine like-terms

x^3 -13x^2 -x -49

(x^2 +6)(x-9)-(4x^2 +7x-5)

x^2 + 6 * x - 9 - 4x^2 - 7x + 5

x^2 + 6x - 9 - 4x^2 - 7x + 5

(x^2 - 4x^2) +(6x - 7x)+(-9 + 5)

(-3x^2)+(-x)+(-4)

=-3x^2 -x - 4

XDdddDddDDDDDDDDDDDDDDDDDDD

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

Work Shown:

f(x) = x+4

y = x+4 ..... since y = f(x)

y = 3p+4 .... replace x with 3p, because x = 3p

(x,y) = (3p, y) .... replace x with 3p

(x,y) = (3p, 3p+4) ... replace y with 3p+4

Answer:

D

Step-by-step explanation:

In an ordered pair, the input is the first value, and the output is the second value.

The input, x, in this case equals 3p, so that will be our first value, which eliminates answers A and B.

Now to find the output, simply plug the input into all instances of x in the equation, like so:

[tex]f(3p) = (3p) + 4 [/tex]

Resolving that, we get 3p + 4 as our second value, which combined with our first value gets us (3p, 3p+4), which is answer D.

Answer:

g=2h-11

Step-by-step explanation:

You need to make the two sides equal, so add  6  to the left side:

[tex](g+5)+6=2h[/tex]

Solve for g

[tex]g+5+6=2h\\\\g+11=2h[/tex]

Isolate g

[tex]g=2h-11[/tex]

Answer:

46.5 miles per hour

Step-by-step explanation:

15 1/2 (15.5)  miles = 1/3 hour (20 minutes)

15.5 miles x 3 = 46.5 miles per hour

Answer:

answer is A

Step-by-step explanation:

This symbol is called a tilde. In symbolic logic (a field of math  

used a lot in computer sciences) it is used to denote "not." For  

example, ~A means "not A." In some other contexts, it means  

"approximately." For example, pi ~= 3.1416. (Note that sometimes it is  

written above the equal sign, and sometimes it is used without an  

equal sign - it depends on the situation and the publisher.)

Answer:

B. A translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin

Step-by-step explanation:

Polygons EFGH and E′F′G′H′ are shown on the coordinate grid:

What set of transformations is performed on EFGH to form E′F′G′H′?

A. A translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin

B. A translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin

C. A 90-degree clockwise rotation about the origin followed by a translation 2 units to the right

D. A 90-degree clockwise rotation about the origin followed by a translation 2 units to the left

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

If a point X(x, y) is translated a units right and b units up, the new location is (x + a, y + b) also If a point X(x, y) is translated a units left and b units down, the new location is (x - a, y - b)

If a point X(x, y) rotated 90-degree counterclockwise about the origin, the new location is X'(-y, k)

Polygon EFGH has vertices E(1, 1), F(1, 4), G(5, 4), and H(4, 1). If the polygon is translated 1 unit right, the new location is E*(2, 1), F*(2, 4), G*(6, 4) and H*(5, 1).

If it is then rotated 90-degree counterclockwise about the origin, the new location is E'(-1, 2), F'(-4, 2), G'(-4, 6) and H'(-1, 5)
