Is -2/3(12b - 6 + 9b - 18) equivalent to 2b(b + 8)? Show your work.

Answers

Answer 1

Answer:

No, they are not equivalent

Step-by-step explanation:

[tex]\frac{-2}{3}(12b - 6 + 9b - 18) = \frac{-2}{3}(12b + 9b - 6 - 18)\\\\=\frac{-2}{3}(21b - 24)\\\\ = \frac{-2}{3}*21b -24*\frac{-2}{3}\\\\= -2*7b + 8*2\\\\= 2( -7b + 8)[/tex]

Answer 2

Answer:

This is NOT equivalent to 2b(b + 8).

Step-by-step explanation:

Start with -2/3(12b - 6 + 9b - 18).  Simplify this.  First, combine the like terms inside the set of parentheses:

(-2/3)(21b - 24)

Simplify this by applying the distributation property of multiplication:

-14b + 16

Finally, factor out 2:  2(-7b + 8)

This is NOT equivalent to 2b(b + 8).

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is 2x+4≥24

Two times of x plus four greater than or equal to twenty four.

Subtract 4 from both the sides

2x≥24-4

2x≥20

Divide both sides by 2

x≥10

Hence, the solution of the inequality 2x+4≥24 is x≥10.

Answer:

the answer is c :)

Step-by-step explanation:

C. 9h + 75 > 150

Step-by-step explanation:

One part is that it says that she makes more than, not more than or equal too 150. Which cuts the options down to two.

A. and C.

The second thing that the text says is that she makes 9 dollars and hour, not 75 an hour. Which means that A. can't be the answer.

Thus, C. is the correct answer.

1/2 =0.25=25%

1/4 =0.25=25%

Answers

Answer:

1/4=0.25=25%

Step-by-step explanation:

A coin has two sides, heads and tails, and if you take 100% divided by two you get 50, you want to know what is the probability it will land on tails TWICE so divide 50 by two and you get 25.

1/2=50

IM STRUGGLING SO BAD HELP ;-; Find the area of the shaded region. Use 3.14 for n.
2 yd
2 yd
3 yd
6 yd
-8 yd —
sydd syd
Syd →

Answers

Answer:

57.74‬ yd²

Step-by-step explanation:

First, find the area of the "rectangle" as if there weren't different figure cut out of it:

(5+6+5)8

16(8)

128 yd²

Next, we are going to find the area of the four figures that are cut out from the rectangle. The circle at the bottom, the rectangle at the top, and the triangles on each side.

The first shape we can tackle will be the circle. The formula for finding the area of a circle is π or in this case 3.14r². The diameter of the circle is 6 yards, and half of the diameter is equal to the radius which gives us 3 yards as the length. Now simplify the expression:

3.14(3)²

3.14(9)

28.26 yd² is the area of the circle.

Next, we're going to find the area of the rectangle at the top. It's dimensions are 6 yards by 3 yards, which gives us an easy 18 yards² as the area (lxw).

Now we're going to solve for the area of the triangles. By the looks of the general dimensions of this shape, I am assuming these triangles are  congruent to each other, which means we will only have to solve for its area once. To find the area of a triangle we have to use the expression: (lxw)/2. However, we don't know one of those dimensions. We know that the length is 8 yards as shown in the diagram, and by using the widths 2 yards and 5 yards, and their relation to the triangle, we can deduce the width is 3 yards. Now we have values necessary to simplify the expression:

(8x3)/2

24/2

12 yards² is the area of one triangle.

Because I stated previously that the triangles are congruent, they both have an area of 12 yards. Now we add the areas of each of the four figures, and subtract them from the area of our large rectangle:

128-(12+12+28.26+18)

128-70.26

57.74‬ yd² is the area of the shaded region

You can complete 40 pushups in 2 minutes. Your friend can complete 57 pushups in 3 minutes. Do these rates form a proportion? Explain

Answers

Answer:

No.

Step-by-step explanation:

In order to find the answer, you have to make the rates as simple as they get: In other words, you have to make it so that the rate has one on each side. Like this:

40:2

20:1

57:3

19:1

As you can see, they don't have the same numbers once their simplified. Which means that they can't be proportional. So, In this specific problem, you can do one more pushup in one minute than your friend can do.

Dilate this by 1/3

Answers

For this shape there are four points. The plotted ordered pairs are:
M = (3, 9)
N = (6, 0)
O = (3, 6)
P = (-3, 0)

All you have to do is multiply the BOTH x- and y-values by 1/3 on EACH ordered pair. And if it’s easier, you can divide by 3 as well. It’s the same thing.

M = (3, 9) = (3*1/3, 9*1/3) = (1, 3)
N = (6, 0) = (6*1/3, 0*1/3) = (2, 0)
O = (3, 6) = (3*1/3, 6*1/3) = (1, 2)
P = (-3, 0) = (-3*1/3, 0*1/3) = (-1, 0)

(1, 3) , (2, 0) , (1, 2) , and (-1, 0) are your points.
