none are parallel

Step-by-step explanation:

1. -28

-4/-7 × -1/4

4/7 × -1/4 = -4/28

2. 7

-4/-7 × 1/1

4/7 × 1/1 = 4/7

3. 35

-4/-7 × 1/5

4/7 × 1/5 = 4/35

Step-by-step explanation:

Use long multiplication to evaluate.

Answer:

  use the slope formula

Step-by-step explanation:

Usually, you are asked for an average slope over some interval. The slope is calculated on that interval the same as it would be if you were given two points, one at each end of the interval.

  m = (y2 -y1)/(x2 -x1)

For example, if you wanted to know the slope on the interval [1, 2] hours, the points you would use would be ...

  (hours, miles) = (1, 25) and (2, 75)

The corresponding slope on that interval is ...

  m = (75 -25)/(2 -1) = 50 . . . . miles per hour

__

You can identify four (4) regions on this graph in which the slope is constant:

  (0, 1) . . . slope is 25 mph

  (1, 2) . . . slope is 50 mph, as computed above

  (2, 3) . . . slope is 0 (the rider has stopped)

  (3, 5) . . . slope is 25 mph

Over different intervals, you need to identify the points involved and use the formula to compute the average slope.

Well, make brainlist okay

1) FH = JH ( GIVEN) Side

2) FG = JK (GIVEN) side

3) GH = HK ( MIDPOINT) side

Neither

Step-by-step explanation:

None of them have the same angles as triange ABC.

Answer:

31.01, 180.8, 0.2, 15501

Step-by-step explanation:

Puzzle 1:

The first rule takes out 301

The second rule has to have a 1 in the units place so that takes out 3.1, 3.101, and 30.1

The 3rd rule takes out 1.01, and 1.03

Rule 4, is self explanatory, so it takes out 31.3

and the last rule takes out 31.1 bc there is no hundredths column

That leaves you with 31.01

Puzzle 2:

Rule 1 takes out 18180

Rule 2, self explanatory, takes out 180

Rule 3 takes out numbers less than 18 so 1.81 and 0.18

Rule 4 takes out  18.01, 1800, 188, and 18.8

That leaves you with 180.8

Puzzle 3:

Rule 1 takes out 0.24, 0.5, and 2.02

Rule 2 takes out 0.15

Rule 3 takes out 0.02, 0.01 and 0.1 (bc it just says greater than and not equal to so it takes this one out)

Rule 4 takes out 0.12

That leaves you with 0.2

Puzzle 4:

Rule 1 takes out 45000

Rule 2 takes out 5401, 5444, and 4544

Rule 3 takes out 5454

Rule 4 does not take out any because all the remaining numbers ( 14500, 15501, 14534, and 10500) have 5 hundreds

Rule 5 takes out 14500, 14534, and 10500

That leaves you with 15501

Hope this helped :)

Answer:

First Row: Given

Second Row: Definition of Regular Polygon

Third Row: Definition of Congruence In Terms of Rigid Motion

Fourth Row: Definition of Regular Polygon

Fifth Row: SAS Triangle Congruence Theorem

Sixth Row: CPCTC

Step-by-step explanation:

This is a basic proof in order to prove that verticals of a polygon are congruent. This should be the right answer since it's the only thing that makes sense to me. I really hope this helps you and thanks for being patient! I've been doing geometry and we have to prove everything we claim in a proof just like this one. However, there was one I kind of guessed on (the third row), but I think it should be correct! I saw from the photo that you have a check answer on the bottom of your screen. Just check the answers that I have for you now and if something is wrong, then we can continue talking about it! Hope this helps!! :)

Answer:

(y + 6)(y - 4)

Step-by-step explanation:

Factor the following:

[tex] \longrightarrow [/tex] y² + 2y - 24

The factors of -24 that sum to 2 are 6 and -4.

So,

[tex] \longrightarrow [/tex] y² + (6 - 4)y -24

[tex] \longrightarrow [/tex] y² + 6y - 4y - 24

[tex] \longrightarrow [/tex] y(y + 6) - 4(y + 6)

[tex] \longrightarrow [/tex] (y + 6)(y - 4)

Answer:

( y-4) ( y+6)

Step-by-step explanation:

= y^2 + ( 6 - 4)y - 24

= y^2 + 6y - 4y - 24

= y( y + 6) - 4(y + 6)

= ( y - 4 ) ( y + 6)

Answer C

Step-by-step explanation:

C because 4i = 5

Answer:

the answer is 56.

Step-by-step explanation:

2 for every 4 = 1 for every two, so 28 multiplied by two.

Answer:

The answer is C. Y= -3x+6

The answer can be found by substitute 0 into x and find the value of y. If the value is same with graph then it is correct.

Answer:

$2.19

Step-by-step explanation:

Given that :

Cost of 3 pounds of grape = $6.57

Cost in dollars = y ; number of pounds = x

Cost in dollars α number of pounds

Cost in dollars = k * number of pounds

k = constant of proportionality

$6.57 = k * 3

$6.57 = 3k

Divide both sides by 3

6.57 / 3 = 3k/ 3

2.19 = k

k = $2.19
