HELP PLEASEEE I WILL GIVE BRAINLIEST

Answer:

The function domain is:

{x|x ≥ -4}

Hence, option 4 is correct.

Step-by-step explanation:

Given the expression of the function

[tex]f\left(x\right)=\sqrt{x+4}[/tex]

We know that the domain of the function is the set of input values for which the function is real and defined

We know that the value inside the radical expression must be greater than or equal to 0 so that the function remains defined.

so

[tex]x+4\ge \:0[/tex]

subtract 4 from both sides

[tex]x+4-4\ge \:0-4[/tex]

simplify

[tex]x\ge \:-4[/tex]

Therefore, the function domain is:

{x|x ≥ -4}

Hence, option 4 is correct.

Step-by-step explanation:

x+1=2x

2x-5

90

like terms;

- crossing over becomes + and vice versa

soo 2x-2x +90-5

2x^2 cancels it self out leaving 90-5

=85.

Answer:

P=2

Step-by-step explanation:

10-2.5(3.2)=P

By order of operations you would multiply 2.5 and 3.2 together giving you 8.

You would then subtract 10-8 giving you 2.

Answer:

d = 4.8 units

Step-by-step explanation:

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )

d = [tex]\sqrt{(x_{2} -x_{1} )^2 + (y_{2} -y_{1} )^2}[/tex]

~~~~~~~~~~~

( - 3, 2.6 )

( - 3, - 2.2 )

d = [tex]\sqrt{(-3+3)^2 +(-2.2-2.6)^2 }[/tex] = √(- 4.8)² = 4.8 units

What statements, the statements aren't listed in the question?

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

The answer is table b

Step-by-step explanation:

Answer:

Only choices C and D are solutions

Step-by-step explanation:

6x + 3y = -15

y = -2x - 5

6x + 3y = -15

6x + 3(-2x - 5) = -15

6x - 6x - 15 = -15

0 = 0

Since 0 = 0 is a true statement, both equations of this system are the same equation and represent a single line on the coordinate plane.

We need to check each choice in just one equation.

Let's use the second equation.

y = -2x - 5

A.

(2, 7)

7 = -2(2) - 5

7 = -4 - 5

7 = -9   False

Not a solution

B.

(5, 0)

0 = -2(5) - 5

0 = -10 - 5

0 = -15     False

Not a solution

C.

(-3, 1)

1 = -2(-3) - 5

1 = 6 - 5

1 = 1   True

Solution

D.

-13 = -2(4) - 5

-13 = -8 - 5

-13 = -13    True

Solution

Answer: Only choices C and D are solutions

You must multiply 8 x 1/4 x 6 to get your answer

Answer: 6 cups

Step-by-step explanation:

You need to find a unit rate...

48/2= 1 cup for 24 cookies (unit rate)

144/24=6 so you need to multiply 1 and 24 each by 6

1*6=6

24*6

to get...

6 cups for 144 cookies

Answer:

18162 widgets

Step-by-step explanation:

Given

[tex]C(x)=0.92x+85000[/tex]

[tex]R(x)=5.6x.[/tex]

Required

Determine the price at break even point

At breakeven point, the following relationship exists

[tex]Rx = C(x)[/tex]

Substitute values for R(x) and C(x)

[tex]5.6x = 0.92x +85000[/tex]

Collect Like Terms

[tex]5.6x - 0.92x =85000[/tex]

[tex]4.68x =85000[/tex]

Make x the subject

[tex]x = \frac{85000}{4.68}[/tex]

[tex]x = 18162.3931624[/tex]

[tex]x = 18162[/tex] --- Approximated

Answer:

a. [tex]dV = 3x^2\ dx[/tex]

b. See Explanation

Step-by-step explanation:

Given

Shape: Cube

Solving (a); Formula that estimates the change in edge length

The volume (V) of a cube is:

[tex]V = x^3[/tex]

Where

[tex]x = edge\ length[/tex]

The change in volume is got by:

[tex]dV = \frac{d}{dx}(x^3)[/tex]

Differentiate [tex]x^3[/tex]

[tex]dV = 3x^2\ dx[/tex]

Where

[tex]dx = x_2 - x_1[/tex] i.e. change in x

Solving (b):

The initial and final edge lengths are not given.

In order to solve this question, I'll assume that x changes from 5cm to 5.01cm

So, we have:

[tex]x = x_1 = 5cm[/tex]

[tex]x_2 = 5.01cm[/tex]

Substitute these values in [tex]dV = 3x^2\ dx[/tex]

[tex]dV = 3 * (5cm)^2 * (5.01cm - 5cm)[/tex]

[tex]dV = 3 * (5cm)^2 * 0.01cm[/tex]

[tex]dV = 3 * 25cm^2 * 0.01cm[/tex]

[tex]dV = 075cm^3[/tex]

Answer:

In other words, the slope of the line tells us the rate of change of y relative to x. If the slope is 2, then y is changing twice as fast as x; if the slope is 1/2, then y is changing half as fast as x, and so on.

Answer: a.) I take a shoe size 12

              b.) Runner B is 35 m from starting line

Step-by-step explanation:

a) The variable h (height) is in inches, so, first, transform feet in inches:

1 ft = 12 in

5ft = 5.12 = 60 in

My height is 5ft 10in, then, my height in inches is: h = 60 + 10 = 70

To determine my shoe size:

[tex]s=\frac{1}{10}(70)+5[/tex]

s = 12

For me, who is 5ft 10in tall, my shoe size is 12.

b) Runner B is 10m in front of the starting line, which means runner's initial position is 10. Linear relationship between speed and position is given by:

[tex]x=x_{0}+v.t[/tex]

where

x₀ is initial position

v is speed

t is time

Replacing and solving:

x = 10 + 2.5t

x = 10 + 2.5(10)

x = 35

After 10s, Runner B is 35 meters ahead of the starting line

Answer:

((c)) man so simple. bye

Answer:

B

Step-by-step explanation:

Graph B represents the values of x when x²<25.

If you take the square root of both sides, you get ±x<5

This means that x is any value in between, but not including, -5 to +5.
