Rewrite the expressions without the absolute value sign.

|x+12| , if x>−11

Answers

If x< -5 then x+5 < 0
but the absolute value of x+5 > 0
X+12 >-11
X> -23
But also you have to write a second equation to get both possible answers for x since it was in absolute value
X+12>11
X>-1
So x > -23, -1

Manuel wants to build a model of a superhero's famous shield. He decides to cut a circular shape out of cardboard. Manuel knows that the outer ring of the shield is colored yellow. The next ring is white. The third ring in is also yellow. The center is white with a green key. The radius of the entire shield is 12 inches; however, Manuel wants to know how much yellow paint he will need so he does some measurements as shown in the diagram below. He measures the radius of the inner circle as 4.5 inches. He measures the radius to the second circle as 7 inches. The radius to the third circle as 9.5 inches. What is the area of the space Manuel will paint yellow? Use 3.14 for pi

Answers

Answer:

B : 259.18in^3

Step-by-step explanation:

find the area of all the circles you have to use the formula A=πr2 and these are the sizes

smallest white : A≈63.62in

yellow 2nd circle: A≈153.94in

3rd circle white: A≈283.53in

largest yellow circle: A≈452.39in

first you have to start with the smallest circle which the area is 63.62 then you go to the 2nd circle which is yellow which the area is 153.94 since you are trying to find only the area of yellow you have to subtract 63.62 from 153.94 which you get 90.32 then you have to go to the 3rd circle which then you have to subtract the 90.32 from 283.53 which comes out to be 193.21 then you finish with the last circle which the area is 452.39 then you have to subtract the last 193.21 which comes out to be 259.18in

the reason you subtract every time you went to the bigger circle because that number was the opposite color if you had 2 yellows in a row you would have to add them just as an example.

The answer is B!!!!!!!!

Which graph shows the solution to the system of linear equations?

y equals one third x

x + 3y = −6

Answers

Answer:So let's start by guesstimating the slopes:

the green line has a slope close to -x, but more negative than that, possibly -2; the pink line has a slope close to +x, but higher towards +2.

Next let's look at the solution: the two lines intersect at the point (1, -1).

**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)

A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2

B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense

C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations

D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1

So the correct answer is:

C) y = 2x - 3 and y = −2x + 1

Step-by-step explanation:

The correct answer is C

Step-by-step explanation: 1. 12.5 yds at 4.50 per yd : 12.5 * 4.50 = 56.25....what she paid for the fabric

she uses 2.5 yds of fabric for each dog bed.....12.5 / 2.5 = 5...so she can make 5 dog beds

each dog bed sells for 17.50.....5 * 17.50 = 87.50

87.50 (what she earned from selling the dog beds) - 56.25 (the cost of the fabric) = 31.25......so her total profit is $ 31.25 <==

First lets add up Rosalva

1.5+0.69+1.04+2.1=5.33

Next lets do Jake

1,450+1,590+1204+1,977=6,221

We have two different measurements, we want them to be the same. We are gonna change Rosalva. One kilometer equals 1,000 meters. If u use the g o o g l e calculator it says that 5.33 kilometers equals 5330 meters. since u need to show work just multiple 5.33 by 1,000.

Last we need to find the difference soooooooo 6,221-5330=891 meter difference :)
