Answer:

x = 2.52

Step-by-step explanation:

30.16 = 17.56 + 5x

30.16 - 17.56 = 5x

12.6 = 5x

12.6/5 = 5x/5

2.52 = x

Answer:

x>4

Step-by-step explanation:

-5x+6<2(-3-x)

-5x+6<-6-2x

-5x+6+2x<-6-2x+2x

-3x+6<-6

-3x<-12

Answer:

X=17.9

Step-by-step explanation:

Given:

The function is [tex]f(x)=3(x+7)^{\frac{1}{4}}[/tex].

To find:

The function [tex]f^{-1}(x)[/tex].

Solution:

We have,

[tex]f(x)=3(x+7)^{\frac{1}{4}}[/tex]

Substitute f(x)=y.

[tex]y=3(x+7)^{\frac{1}{4}}[/tex]

Interchange x and y.

[tex]x=3(y+7)^{\frac{1}{4}}[/tex]

Divide both sides by 3.

[tex]\dfrac{x}{3}=(y+7)^{\frac{1}{4}}[/tex]

Taking power 4 on both sides.

[tex]\left(\dfrac{x}{3}\right)^4=y+7[/tex]

Subtract 7 from both sides.

[tex]\left(\dfrac{x}{3}\right)^4-7=y[/tex]

[tex]y=\left(\dfrac{x}{3}\right)^4-7[/tex]

Substitute [tex]y=f^{-1}(x)[/tex].

[tex]f^{-1}(x)=\left(\dfrac{x}{3}\right)^4-7[/tex]

Therefore, the correct option is C.

Answer:

2, 8, 14, 20, 26

Step-by-step explanation:

At n=0

2 x 0 +2=2

At n=1

6 x 1 +2=8

At n=2

6 x 2 +2 = 14

At n=3

6 x 3 +2 = 20

At n=4

6 x 4 +2 = 26

Answer:

9 Cups

Step-by-step explanation:

Answer:

The answer is 9 cups.

Step-by-step explanation:

You know that you need 1.5 cups for each cake. And you know that you need to make 6 cakes. So you just multiply 1.5 by 6.

1.5*6=9

Answer:

Step-by-step explanation:

The curve has a relative maximum where values on either side are lower. This looks like a peak in the curve. There is one of those on the y-axis at y = -4.

The relative maximum is -4.

__

A relative minimum is a low point, where the curve is higher on either side. There are two of these, located symmetrically about the y-axis. The minimum appears to be about y = -5. (They might be at x = ± 1, but it is hard to tell.)

The relative minima are -5.

__

A minimum or maximum is absolute if no part of the curve is lower or higher. Here, the minima are absolute, while the maximum is only relative. (The left and right branches of the curve go higher than y=-4.)

_____

Identifying the points on the curve should be the easy part. Deciding what the coordinates are can be harder when the graph is like this one.

Answer:

True

Step-by-step explanation:

Plug in the point:

-2-(-1)=-2+1=-1<0.

This is a true statement

Answer: The average rate of change of the function in that interval is r = -1

Step-by-step explanation:

When we have a function f(x), the average rate of change in an interval:

a ≤ x ≤ b

Is calculated as:

[tex]rate = \frac{f(b) - f(a)}{b - a}[/tex]

In this case, the function is:

y = f(x) = (1/2)*x^2 - 1

And the interval is:

-2 ≤ x ≤ 0​

Then the rate of change will be:

[tex]rate = \frac{f(0) - f(-2)}{0 -(-2)} = \frac{((1/2)*(0)^2 - 1) -((1/2)(-2)^2 - 1)}{2} = \frac{-2}{2} = -1[/tex]

The average rate of change of that function in that interval is r = -1

Answer:

r = (C - By) / A

Step-by-step explanation:

Ar + By = C

_________

-By -By

[Subtract both sides by By (Subtraction poe)]

Ar = C - By

________

(Ar) = (C - By)

[Use parenthesis to group both terms (Associative property of equality)]

________

÷A ÷A

[Divide both sides by A to isolate r so it can be solved (Division poe)]

________

r = (C - By) / A

Step-by-step explanation:

Answer: Adults = 58

Children = 42

Step-by-step explanation:

Let adults be denoted as a

Let Children be denoted as c

a + c = 100 ...... i

10a + 5c = 710 ...... ii

Multiply I by 5

Multiply ii by 1

5a + 5c = 500 ...... iii

10a + 5c = 710 ...... iv

Subtract iii from iv

5a = 210

a = 210/5

a = 42

Since a + c = 100

c = 100 - 42 = 58.

Adults = 58

Children = 42

Answer:

        y + 2 = ⁶/₅(x - 5)     {the point-slope form of the equation}

        y = ⁶/₅x - 8            {the slope-intercept form of the equation}  

         6x - 5y = 40           {the standard form of the equation}

Step-by-step explanation:

The point-slope form of equation is: y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope.

m = ⁶/₅

(5, -2)    ⇒   x₀ = 5,  y₀ = -2

So, the point-slope form of the equation:

y + 2 = ⁶/₅(x - 5)

Therefore:

y + 2 =  ⁶/₅x - 6          {subtract 2 from both sides}

y = ⁶/₅x - 8              ←  the slope-intercept form of the equation

-⁶/₅x + y = - 8                    {multiply both sides by (-5)}

6x - 5y = 40               ←  the standard form of the equation
