Answer:

Step-by-step explanation:

we're given that

[tex]W = 2X - 3\\P = 43\\[/tex]

the perimeter can be defined as

[tex]P = 2X + 2W \\so\\43 = 2X + 2(2X - 3)\\43 = 2X + 4X - 6\\6X = 49\\X = \frac{49}{6}\\ W = 2X - 3\\W = 2(49/6) - 3\\W = 49/3 - 9/3 = \frac{40}{3}[/tex]

The rectangle is

[tex]\frac{49}{6} by \frac{40}{3}[/tex] feet

J' (3, 2)

Step-by-step explanation:

when a point is rotated 90 degrees clockwise, the point goes from (x, y) to (y, -x). You can imagine this rule or come up with it by doing a rotation on a graph, but really it's just a rule you should memorize.

So, apply (x, y) --> (y, -x) to this point:

(-2, 3) --> (3, 2)

Answer: m= 3/7

Step-by-step explanation: in y=mx+b form this equation is y=3/7 x + 11/7

Answer:y = -2/3x + 490

Step-by-step explanation:

2x +3y = 1470  

Slope intercept form definition: y = mx + b is the slope-intercept form of a line where m is the slope and b is the y-intercept.  

2x + 3y = 1470  

2x + 3y -2x = 1470 - 2x - Subtract 2x from both sides  

3y = 1470 - 2x - Simplify  

3y/3 = 1470/3 - 2x/3 - Divide both sides by 3  

y = -2/3x + 490 - Simplify  

-⅔ is the slope and 490 is the y-intercept

you create 15 per 5 hours.  or 15 centerpieces/5 hours or 3 centerpieces per hour.  To make 42, if you make 3 per hour, you would divide 42 by 3, getting 14.  It will take 14 hours to make 42 centerpieces.

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question

Ahmed is riding the elevator in a building. The building has floors above and below ground level. Ahmed uses the expression below to describe his movement. 6 + (–8) Which statement could describe Ahmed’s movement?

Given the expression

6+(-8)

Let's denote upward movement in the elevator as positive and downward movement as negative.

+6 means that Ahmed rides 6 floors above in the elevator (since +be means upward movement in the elevator)

-8 means that from that 6th floor, he then moves 8 floors downwards in the elevator. In other to determine the floor Ahmed is, we can evaluate the given expression:

= 6+(-8)

Note that -×+ = -, hence the expression becomes;

= 6-8

= -8+6

= -2

This means that Ahmed is 2 floor below or down the elevator.

Answer: He moved 6 floors up, then moved 8 floors down. So he is now 2 floors below ground level.

-20/27

Step-by-step explanation:

Multiply the top denominators

-8•5= -40

Multiply the bottom denominators

9•6=54

So 40/54

Now simplify

-40/54 ÷ 2= -20/27

Answer:

B x= -9

Step-by-step explanation:

if you graph x equals negative 9 you always have a vertical line

Answer: b) x = -9

a) gives you a diagonal line when you graph it

b) gives you a vertical line since you only have the x-value, and it passes through the point (-9,10) when you graph it

c) gives you a horizontal line when you graph it since you only have the y-value

Answer:

30

Step-by-step explanation:

Answer:

There are 30 students in his math class

Step-by-step explanation:

First you subtract the three from 123 because that three he still has. Then you take the 120 and divide it by four since thats how many pieces he gave each student. You are then left with 30 students.

Answer:

x=1.4

Step-by-step explanation:

12x-15=6-3x

15x=21

x=21/15

x=1.4

12(1.4)-15=6-3(1.4)

16.8-15=6.4.2

1.8=1.8

Answer: x = 6 or just 6

Step-by-step explanation: You do the opposite of addition, and subtract +5 and 23 to get 3x = 18, then you would divide 3x and 18 by 3 to get x = 6 or just 6.

Answer: x = 5

Step-by-step explanation:

10x and 130 degrees are supplementary, because they are interior angles and the lines are parallel.

10x + 130 = 180

10x = 50

x = 5

Answer:

D

Step-by-step explanation:

Trust me I used a calculator and and different one to make sure my answer was correct.

{14, 48, 50} represents a Pythagorean Triple, hence option (D) is correct.

If three sides of any triangle are a, b and c and c is the largest one then the condition that a, b and c will form a Pythagorean triplet is as:

c² = a² + b²  -----(1)

An option which will satisfy the condition (1) will form a  Pythagorean Triple.

Let's check for all the given options:

A) {10,5,12}

Since, 12 is the largest number out of three.

Therefore, c = 12, a = 5, b = 10

Now,

a² + b²  = 5²+10²

a² + b² = 25+100

a² + b² = 125

a² + b²≠ 15²

a² + b²≠ c²

Hence,  {10, 5, 12} will not form a Pythagorean Triple. Option (A) is incorrect.

B) {2,4,5)

c = 5, a = 2, b =4

a² + b² = 2²+4²

a² + b²  = 4+16

a² + b² = 20

a² + b² ≠ 5²

Hence, option (B) is also incorrect.

(C)  {1,2,3}

c = 3, a = 1, b = 2

a² + b² = 1²+2²

a² + b² = 1+4

a² + b²= 5

a² + b² ≠ c²

This is also not forming a  Pythagorean Triple, that is why incorrect.

(D) {14, 48, 50}

c = 50, a = 14, b = 48

a² + b² = (14)²+(48)²

a² + b² = 196 +2304

a² + b²  = 2500

a² + b²  = (50)²

a² + b²  = c²

This satisfies the condition (1) hence, it is forming a Pythagorean Triple.

This option is an  appropriate choice.

Hence, option (D) is correct, that means {14, 48, 50} represents a Pythagorean Triple.
