Answer:

J´ (-1, 3), K´(-4,1) L´(-8,4)

Step-by-step explanation:

Just move each coordinate down 9.

Answer:

Step-by-step explanation:

Circumference of a circle: C = 2*π*r

22/7 or π = 3.14

r (radius) = d/2

5. d/2 = 2

r = 10/2 = 5 cm.

C = 2*π*r

C = 2*3.14*5

C = 10*3.14

C = 31.4 cm.

6. r = 90 in.

C = 2*π*r

C = 2*3.14*90

C = 180*3.14

C = 565.2 in

7. r = 16 yd.

C = 2*π*r

C = 2*3.14*16

C = 32*3.14

C = 100.48 in

8. r = 4 in.

C = 2*π*r

C = 2*3.14*4

C = 8*3.14

C = 25.12 in.

9. d/2 = 2

r = 22/2 = 11 cm.

C = 2*π*r

C = 2*3.14*11

C = 22*3.14

C = 69.08 cm.

10. d/2 = 2

r = 4/2 = 2 m.

C = 2*π*r

C = 2*3.14*2

C = 4*3.14

C = 12.56 m.

11. In short words, a radius is half of its diameter. So a circle with a diameter of 8 cm has a radius of 4 cm because r = d/2. 8/2 = 4 cm.

Hope this helps!

Answer:

1. C = 31.4 cm. 2. C = 565.2 in 3. C = 100.48 in 4. C = 25.12 in. 5. C = 69.08 cm. 6. C = 12.56 m.

Answer:

-16

Step-by-step explanation:

As we have

[tex] {x}^{2} - {y}^{2} = (x + y)(x - y)[/tex]

Here

x= -3

y= -5

Subtitute x and y

[tex] {x}^{2} - {y}^{2} \\ ( - 3{)}^{2} - ( - 5 {)}^{2} \\ 9 - 25 \\ - 16[/tex]

Answer:

-16

Step-by-step explanation:

We first need to substitute

Since x = -3 and y = -5

(-3+-5)(-3 - -5)

Let's Solve (-3+-5)

which = -8

Then Solve (-3 - -5)

which = 2

Now -8 × 2 = -16

Hence, Answer = -16

Answer:

3 1st class tickets

5 coach tickets

Step-by-step explanation:

Quantity:: C + F = 8

Value:: 380C + 1180F = 5440

Modify;:

1180C + 1180F = 1180*8

380C + 1180F = 5440

Subtract and solve for "C"::

800C = 4000

C = 5 (# of coach tickets)

Let x = number of 1st class tickets

8-x = number of coach tickets

and

She bought 3 1st class tickets

She bought 5 coach tickets

Answer:

10°

Step-by-step explanation:

Answer:

67.6

Solving Steps:

=> 2x³ + 3.4y

=> 2(3)³ + 3.4(4)

=> 2(27) + 13.6

=> 54 + 13.6

=> 67.6

Hey there!

1/2x^3 + 3.4y

= 1/2(3)^3 + 3.4(4)

= 1/2(3 * 3 * 3) + 3.4(4)

= 1/2(9*3) + 3.4(4)

= 1/2(27) + 3.4(4)

= 27/2 + 3.4(4)

= 13.5 + 13.6
= 27.1

Therefore, your answer is: 27.1

Good luck on your assignment & enjoy your day!

Answer:

5/6 + (-1/4) + (-2/3)

Step-by-step explanation:

5/6 - 1/4 + (-2/3) = -1/12

5/6 + (1/4 )+ (-2/3) = -1/12

Answer:

18 cups

Step-by-step explanation:

Because there is 4 cups in a quart, we can turn 5 1/2 or 5.5 quarts into 22 cups:

5 1/2 or 5.5

( 5 x 4) + (0.5 x 4) = 22

Since we need to find how many cups were used, that is x. Because 22 cups is the total amount of cups and 4 is the amount remaining then the equation would look like this:

x + 4 = 22

Finally you solve to get:

x = 18 cups

Answer:

your answer is C

explanation:

your answer is C because when you look at function 1 you see what Y equals and then you look at function 2 you see what Y and X equals and on both of them they increase. They increase to me but I don’t know about other people

Answer:

Result: $26.46

Steps:

$24.50 (increase) + 8% = $26.46

24.50 x (1 + 8%) = 24.50 x (1 + 0.08) = 26.46

I'm truly sorry if my math is incorrect.

Bye, have a great day/night  :)

Answer:

$26.46

Step-by-step explanation:

1 example $24.50*(108%)

24.5*1.08

= $26.46

2nd example 24.5+1.96=26.46

Also 8% of 24.5 is 1.96

Answer:

C. y = 3x + 14

Answer:

A. y = 3x – 10

Step-by-step explanation:

We have equation of line passing through two points (x1, y1) and (x2, y2) as,

(y - y1) = [(y2 - y1)/(x2 - x1)] (x - x1)

(y + 4) = [(2 + 4)/(4 - 2)] (x - 2)

(y + 4) = (6/2)(x - 2)

(y + 4) = 3(x - 2)

3x - y - 10 = 0 --- (1)

Now, slope-intercept form of line is y = mx + c

Rearranging equation (1) ⇒ y = 3x - 10

Therefore, the required equation is y = 3x - 10

Answer:

The length of side XZ should be greater than 10 and lesser than 60.

Step-by-step explanation:

In triangle XYZ ,

As

The length of side XY = 25 mm

The length of side YZ = 35 mm

Range of the third side can be computed when we already know the two sides of the triangle.

If subtracting  , the 3rd side would have to be more than 10. Else 3rd side can not be made as two smaller legs will not meet.

and

If adding  , the 3rd side would have to be less than 60. Else 3rd side will reach further than the the other two sides could reach.

Therefore, the length of side XZ should be greater than 10 and lesser than 60.
