Answer 1

Answer:

perpendicular

Step-by-step explanation:

L1: find the slope

rise: 2 - (-5) = 7

run: -1 - (-3) = 2

m1 = 7/2

L2:

rise: 2 - 4 = -2

run: 7 - 0 = 7

m2 = -2/7

parallel means same slope m1 = m2

perpendicular means opposite reciprocal (flip and change signs)

7/2 flip and change signs = -2/7, yes thus it is perpendicular

Step-by-step explanation:

always remember to square root if not answer will be counted as incomplete or incorrect!

Answer:

1) response b

2) x=35 (response c)

3) response d

Step-by-step explanation:

1) The Pythagorean  theorem's "C" value is the value of your hypothenuse, which means that it would be c^2-b^2=a^2

You would set it up as "7^2-4^2", and then to get rid of the squared value, you would have to square root it

2) In this question, you're finding the hypothenuse, therefore the two values given are your "a" and "b" values.

                                                 [tex]\sqrt{21^{2} +28^{2} } =x[/tex]

                                                 [tex]\sqrt{441+784}=x[/tex]

                                                     [tex]\sqrt{1225} =x[/tex]

                                                        x=35

3) This is pretty much self explanatory if you know the C value is the hypotenuse

                                                      [tex]\sqrt{4^{2}+5^{2} }[/tex]

                                                      [tex]\sqrt{16+25}[/tex]

                                                          [tex]\sqrt{41}[/tex]

In a standard deck of cards, what is the probability of drawing a face card?

Answer (round) to the hundredth place value.

Answers

Answer:  0.23

Reasoning:

There are 12 face cards since there are 3 face cards in any suit, and 4 suits. So 3*4 = 12.

There are 52 cards total.

Dividing the values leads to 12/52 = 0.230769 which rounds to 0.23

ASA and AAS cannot be used because we can only confirm one angle of each triangle.

Congruent shapes have equal corresponding sides and angles.

The congruence theorems that can be used to prove [tex]\triangle ABR \cong \triangle ACR[/tex] are HL, SAS, and SSS

[tex]\triangle ABR \cong \triangle ACR[/tex] means that, the triangles are congruent.

can someone help me

Answers

Answer:

x=-2

Step-by-step explanation:

To find the value of x you will have to isolate the x.

6x-3=5x-5 ------> Add 3 to both sides to get rid of the 3

6x=5x-2 ------> Subtract 5x to both sides to get rid of the 5x

1x=-2

1x is the same as x so

There are 15 books on a shelf. 8 of these books are new. The rest of them are used.


(a) What is the ratio of used books to all books on the shelf?

(b) What is the ratio of new books to used books?

Answers

Answer:

a. 7:15

b. 8:7

Step-by-step explanation:

there are 7 used books and 8 new books, thus, there are 15 books on a shelf.

(a) The ratio of used books to all books on the shelf is [tex]\dfrac{7}{15}[/tex].

(b)The ratio of new books to used books is  [tex]\dfrac{8}{7}[/tex].

Given that:

Total number of books = 15

Total number of  new books = 8

Total number of used books= 15-8

                                              = 7

(a) The ratio of used books to all books on the shelf is calculated as:

  Ratio = [tex]\dfrac{ Used \ books}{ Total \ books}[/tex]

           = [tex]\dfrac{7}{15}[/tex]

(b)  The ratio of new books to used books is calculated as:

    Ratio = [tex]\dfrac{ New \ books}{ Used \ books}[/tex]

             = [tex]\dfrac{8}{7}[/tex]

Thus, the ratio of used books to all books on the shelf is  [tex]\dfrac{7}{15}[/tex]  and the ratio of new books to used books is [tex]\dfrac{8}{7}[/tex].

Teal Street is the line 2x - 3y = 9 Write out this equation as y = mx + b​

Answers

Answer:

[tex]y = \frac{2}{3} x - 3[/tex]

Step-by-step explanation:

For the equation to be written in the form of y=mx+b, ensure that the y term is on one side of the equation and bring the rest to the other side. Then divide the whole equation by the coefficient of y, so that the resulting coefficient of y is 1.

2x -3y= 9

-3y= -2x +9 (-2x on both sides)

Dividing both sides by -3:

[tex]y = \frac{2}{3} x - 3[/tex]

☆ coefficient is the number that comes before a term

disagree

at first glance, you would agree that a # to the third power would be greater, however, when the base is a negative #, the result is a negative and smaller #.
