What is the domain of the function?
A.) (-00,00)
B.) (-2.1,0)
C.) (-3,3)
D.) (2.2,00)

Answer:

x ≥ -4 or x ≥ [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

9 ≤ | 4x + 7 |

4x + 7 ≥ 9

4x ≥ 2

x ≥ [tex]\frac{1}{2}[/tex]

4x + 7 ≥ -9

4x ≥ -16

x ≥ -4

area of the whole figure

= (x + 1)(2x + 3)

= x(2x + 3) + 1(2x + 3)

= 2 {x}^{2} + 3x + 2x + 3

= (2x)^(2} + 5x + 3

area of the unshaded region

= x(2x)

= 2x²

area of the shaded region

= 2x² + 5x + 3 - 2x²

= (2x² - 2x² ) + 5x + 3

= 5x+ 3

THEREFORE,

THE AREA OF THE FRAME IS C. 5x + 3

Step-by-step explanation:

Answer:

12 different outfits

Step-by-step explanation:

3 shirts

jeans or skirt: 2 choices

boots or flats: 2 choices

If you have several thing you can do and each one has a number of choices, the total number of variations is the product of the numbers of choices.

3 * 2 * 2 = 12

Answer: 12 different outfits

Step-by-step explanation: If you multiply the amount of workers by two, then you divide the amount of time by two, and vice versa. So, in other words, whatever number you multiply the workers by, divide the time by that same number. I hope this helps!

Answer:

40B +30M ≤ 300

200B +80M ≤ 1200

Step-by-step explanation:

The inequality functions are as follows:

For 40 cartridges per book and 30 cartridges per magazine and at most 300 cartridges are used

So the function would be

40B +30M ≤ 300

Now the another would be

There are 200 pages for printing a book and 80 pages are required for printing a magazine also she used at most 1,200 pages

So, the function would be

200B +80M ≤ 1200

Answer:

40

Step-by-step explanation:

i would say 40? because it will be a constant for how many times you do X. for example if it's Y = 40 (2) it would equal 80 because no matter what number you put in X 40 will have to be multiplied

Answer:

B=55

Step-by-step explanation:

Answer:

he sold 22 dogs and 13 cats

number of dogs = 22

plz mark my answer as brainlist plzzzz and option C .22 is the correct answer

Answer:

c. 22

Step-by-step explanation:    

75 x 22= 1650

35-22=13

13 x 25= 325

325+1650= 1975

Answer:

hosta = 2 $,,, geranium = 5 $

Step-by-step explanation:

if we make two eq.

1) .... 54 = 2h + 10g

2) ...... 40 = 10h + 5g

if we multiply 1st by -5 it turns to

3) ..... -270 = -10h - 50g

cancel both 10h

add eq. .. becomes : -230 = -46g

g = 5

substitute in any find , that h = 2

Answer:

y = 0 is parallel to y= 4 ..plz mark my answer as brainlist plzzzz if correct

Answer: 5/8 of the project is done

Answer:

The negative solution = x = -4

Step-by-step explanation:

Let the number be = x

The square of number = x²

The difference between the square of a number and 28 = x²-28

Given that the difference of the square of a number and 28 is equal to three times that number.

Thus, the equation becomes

[tex]x^2-28=3x[/tex]

subtract 3x from both sides

[tex]x^2-28-3x=3x-3x[/tex]

[tex]x^2-3x-28=0[/tex]

[tex]\left(x+4\right)\left(x-7\right)=0[/tex]

[tex]x+4=0\quad \mathrm{or}\quad \:x-7=0[/tex]

[tex]x=-4,\:x=7[/tex]

Thus, the negative solution = x = -4

Answer:

x = 2 , y = 0 , z = 3

Step-by-step explanation:

Cramer's rule is a rule through which we can find the solution of linear equation.

we have the three linear equations as

x+2y+3z=11

2x+y+2z=10

3x+2y+z=9

AX=B  

A: coefficient matrix

X= unknown vectors(x,y,z)

D = values of the linear equation (11 , 10 , 9)

now we find the determinant of the given linear equation

determinant of the matrix will be

A = [tex]\left[\begin{array}{ccc}1&2&3\\2&1&2\\3&2&1\end{array}\right][/tex]  = 1(1-4) - 2(2-6) + 3(4 - 3)

                    = 1(-3) - 2(-4) + 3(1)

                    = -3+8+3 = 8

also D[tex]\neq 0[/tex]

so the determinant is Non zero we can apply Cramer's rule

we will be replacing the first column of the coefficient matrix A with the values of D

by replacing the first column we will get the value of the variable 'x'

Dx =  [tex]\left[\begin{array}{ccc}11&2&3\\10&1&2\\9&2&1\end{array}\right][/tex]   = 11(1-4) -2(10-18) + 3(20-9) = -33+16+33 = 16

x = [tex]\frac{Dx}{D}[/tex]  = [tex]\frac{16}{8}[/tex] = 2

similarly

Dy = [tex]\left[\begin{array}{ccc}1&11&3\\2&10&2\\3&9&1\end{array}\right][/tex] = 1(10-18) -11(2-6) + 3(18 -30) = -8 +44 -36 = 0

y = [tex]\frac{Dy}{D}[/tex] = 0

Dz= [tex]\left[\begin{array}{ccc}1&2&11\\2&1&10\\3&2&9\end{array}\right][/tex] = 1(9 - 20) -2(18 - 30) + 11(4 -3) = -11 +24 +11 = 24

z = [tex]\frac{Dz}{D}[/tex] = [tex]\frac{24}{8} = 3[/tex]

so we have the solution as

x = 2 , y = 0 , z = 3

Therefore the solution for the given linear equations is (2,0,3).

Answer:

x = 3.8 + 53.6

Step-by-step explanation:

From the info that they gave you, you can tell that the original number is unknown, so that is x. Since Sushil is subracting 3.8, meaning, to get x, you're going to have to do the opposite which is........addition! So, to get x, you have to add 3.8, and 53.6. I hope I make sense!!

Answer:

Both are related as both have the answer same that is x=2.
