Answer:

x = -4

Step-by-step explanation:

-9 (1/2x - 3) = 45

Divide both sides by -9

Match the verbal statement to the correct value.

One–third of the product of −8 and 9
Half the sum of 8 and −6

One-fifth the product of 1 and −5
Five times the sum of −8 and 4

Answers:

-24
-20
-1

18

Answers

Answer:

down below.

Step-by-step explanation:

One–third of the product of −8 and 9 = -24

-8(9) = -72

-72 / 3 OR -72(1/3) = -24

Half the sum of 8 and −6 = 1

8 + (-6) =2

2 / 2 = 1

Three times the sum of 12 and −6 = 18

12 + (-6) = 6

6 * 3 = 18

One-fifth the product of 1 and −5 = -1

1(-5) = -5

-5/5 = -1

Five times the sum of −8 and 4 = -20

-8 + 4 = -4

-4 * 5 = -20

1. -24
2. 1
3. 18
4. -1
5. -20

What is the scale factor of the dilation?

Is the dilation an enlargement or a reduction?

Answers

Answers:

Scale Factor = 3/4

This is a reduction

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

Explanation:

Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).

Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '

we have x = 4 jump to 4k which is the x coordinate of point R'

So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75

We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.

Answer:

A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement is a dilation that creates a larger image

Can someone give me a small lesson on nets and surface areas??

Thank you if you can. I really don’t understand.

Answers

Hi!

Here is the definition of a net from www.icoachmath.com:

“Net is a two-dimensional pattern of a three-dimensional figure that can be folded to form the figure. In other words, net is a flattened three-dimensional figure which can be turned into the solid by folding it.”

In the photo is an example of a net of a rectangular prism.

Surface area is the measure of the total area of the surface of a 3D object. For example, if I have a cube, the surface area would be the area of the outside of the cube.

Hope this helped,

Caroline

a net is just the sides of a 3d shape ‘unfolded’.

Alright so A triangles perimeter is always going to be 90°

So for #1 You would add 18+24= 42 then subtract 42 from 90. 90-42=48. So for the first equation the side would be 48ft.

And for #2 You add 41+40= 81 then subtract 81 from 90 90-81=9 so the answer to the second equation would be 9 ft.

Hope this helps! :)

Answer:

Step-by-step explanation:

a² + b² = c² (pythagorean theorem formula)

let's take 18 as a and 24 as b

So, you'll write it as

18² + 24² = c²

324 + 576 = 900²

c² =810000

c= [tex]\sqrt810000[/tex] = 900

c=900ft
