Answer:

x + 11

Step-by-step explanation:

out you're going from -3 to 8 and that is 11 jumps so if x is -3 then it would be  x + 11

Answer:

Option C: C and D

Step-by-step explanation:

A function, as a rule, can't have multiple output for an input. Also try the vertical line test. If there is more than one point in an imaginary vertical line, then it is not a function.

The function is also defined at x = 0 thus the domain is all real numbers and the range is y ≥ 0 thus option (b) is correct.

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

As per the given graph.

The graph is the function of y = |x|

At x = 0 , y = 0 (defined)

And the function goes x = -∞ to ∞

Hence "The function is also defined at x = 0 thus the domain is all real numbers and the range is y ≥ 0".

Answer:

6(x) + 8 [tex]\geq[/tex] 32

x = 4, 3, 2, 1, 0

Step-by-step explanation:

This is the answer because:

1) 8 more than 6 times a number is 6 times x + 8

6(x) + 8

2) "is at least 32" means 6(x) + 8 [tex]\geq[/tex] 32

3) x = 4, 5, 6, 7, 8 and etc. because -8 from +8 and 32

6(x) = 24

4) 6(4) = 24

5) x can equal anything less than 4

Therefore, the inequality is 6(x) + 8 [tex]\geq[/tex] 32 and x = 4, 3, 2, 1, 0

Hope this helps! :D

Answer:

u = 4

Step-by-step explanation:

1. Distribute the 2 into the parenthesis.

2(4u-9) = 14

x2 x2

8u - 18 = 14

2. Try to get your variable on one side.

8u - 18 = 14

+18 +18

8u = 32

3. Last is to divide so your variable is on the left side of the equation.

8u = 32

÷8. ÷8

u = 4

Answer:

g = 16/3

Step-by-step explanation:

Answer:

g=16/13

Step-by-step explanation:  

3g - 6 + 2g + 1 = 11 - 8g

     5g   - 5  = 11  - 8g

__ +8g________+8g____

     13g   - 5   = 11

 ______+5__+5____

     13g   =       16/13

And 16 goes into 13 once same with 13 going into 16 so it can't be simplified.

your answer is g= 16/13

Answer:

z= 68

Step-by-step explanation:

First Step is to distribute... This simply means to remove the brackets so we have to multiply 4 by both z and 6... lets go...

4 (z + 6) = 296

4z + 24 = 296

Secondly, Send all letters on one side of the equal sign (preferrable the left) and all numbers on the other side...Just remember when ever you sending a letter or number across the equal sign, the sign of the number/letter changes... i.e it will change from positive (+) to negative (-) or vice versa... lets go...

4z + 24 = 296

4z = 296 - 24

4z = 272

z = 272/4

z = 068

Answer:

Option (A)

Step-by-step explanation:

Domain of a function is defined by the x-values (input values) on the graph.

Range of a function is defined by the y-values (output values).

For a function having equation as,

y = x

Since, the given function is defined for all real numbers.

Domain of the function: {x | x ∈ R}

Range of the function: {y | y ∈ R}

Therefore, option (A) will be the answer.

Step-by-step explanation:

Look at the photo for explanation and answer

Answer:

L = 37 yards and B = 76 yards

L = 38 yards and B = 76 yards

Step-by-step explanation:

Given:

Total length of the fence(perimeter) = 150 yards

One side is fenced using the back side of the house

So, we have

Perimeter of the fence = 2L + W

150 = 2L + W (1)

The fenced-in portion = 2,812 square yards

Area of a rectangle = L × W

2812 = L × W (2)

From (1)

150 = 2L + W

W = 150 - 2L

Substitute W = 150 - 2L into (2)

2,812 = L × W (2)

2,812 = L × (150 - 2L)

2,812 = 150L - 2L²

-2L² + 150L - 2812 = 0

2L² - 150L + 2812 = 0

Divide through by 2

L² - 75L + 1406 = 0

Solve the quadratic equation using factorization method

Find the factors

L² - 37L - 38L + 1406 = 0

L ( L - 37 ) - 38 ( L - 37 ) = 0

( L - 37 ) ( L -38 ) = 0

L - 37 = 0 or L - 38 = 0

L = 37 yards or L = 38 yards

If L = 37 yards

B = 150 - 2L

B = 150 - (2 × 37)

= 150 - 74

= 76 yards

If L = 38 yards

B = 150 - 2L

B = 150 - (2 × 38)

= 150 - 76

= 74 yards

Therefore,

The dimensions of the fence can either be

L = 37 yards and B = 76 yards

L = 38 yards and B = 76 yards

Answer:

x = [tex]\frac{56}{3}[/tex]

Step-by-step explanation:

Given

[tex]\frac{9}{24}[/tex] = [tex]\frac{7}{x}[/tex] ( cross- multiply )

9x = 168 ( divide both sides by 9 )

x = [tex]\frac{168}{9}[/tex] = [tex]\frac{56}{3}[/tex]

Answer:

x = 56/3

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 9/24 = 7/x

Then the value of x will be,

→ 9/24 = 7/x

→ 9 × x = 7 × 24

→ 9x = 168

→ x = 168/9

→ [ x = 56/3 ]

Hence, the value of x is 56/3.

Since the triangles are similar, we can use ratios to solve

12        ?

----- = -------

3         5

Using cross product

12*5 = 3?

Divide each side by 3

60/3 = 3?/3

20 = ?

The unknown side is 20

Answer:

Step-by-step explanation:

Since the triangles are similar, all the side lengths can be multiplied by a scale factor,

12/3 = 4, so the scale factor is 4, which

5 x 4 = 20, so the missing side length is 20

Answer:

The number would have to be added is 9

Step-by-step explanation:

To find the form of the completing square of the quadratic function:

Let us do these steps with our question

∵ x² + 10x + 16 = 0

→ Divide the coefficient of x by 2

∵ The coefficient of x is 10

∴ 10 ÷ 2 = 5

→ Square the 5

∵ (5)² = 25

→ Subtract the numerical term from 25

∵ The numerical term = 16

∵ 25 - 16 = 9

∴ We must add 9 to 16 to get 25

→ (x² + 10x + 16 + 9) - 9 = 0

→ (x² + 10x + 25) = 9

→ (x + 5)² = 9

The number would have to be added is 9
