Answer:

First is <  2nd is = 3rd is <

Step-by-step explanation:

Answer:

See Below.

Step-by-step explanation:

By definition, if two functions, f and g, are inverses, then:

[tex]\displaystyle f(g(x)) = g(f(x)) = x[/tex]

We are given the two functions:

[tex]\displaystyle g(x) = \sqrt{x + 8} -4 \text{ and } f(x) = x^2 + 8x + 8[/tex]

Find f(g(x)) and g(f(x)):

[tex]\displaystyle \begin{aligned} f(g(x)) &= (\sqrt{x + 8} -4)^2 + 8(\sqrt{ x+ 8}-4) + 8 \\ \\ &= ((x+8) -8\sqrt{x + 8} +16) + 8\sqrt{x + 8} - 32 + 8 \\ \\ &= x + (-8\sqrt{x+8} + 8\sqrt{x + 8}) +(16 - 32 + 8 + 8) \\ \\ &= x \stackrel{\checkmark}{=} x\end{aligned}[/tex]

And:

[tex]\displaystyle \begin{aligned}g(f(x)) &= \sqrt{(x^2 + 8x + 8) + 8} - 4 \\ \\ &= \sqrt{x^2 + 8x+16 } - 4 \\ \\ &=\sqrt{(x+ 4)^2} - 4 \\ \\ &= (x +4) - 4 \\ \\ &= x \stackrel{\checkmark}{=} x \end{aligned}[/tex]

Hence, f and g are indeed inverses of each other.

A (3)(-17.25) = -51.75

This is the answer because Paul took 17.25 from his saving every week, so that would make 17.25 negative in the equation. 3 is just the number of weeks, there is no need for a negative there.

Answer:

y = -2

Step-by-step explanation:

3(y-2)=2y-8

3y - 6 = 2y - 8

y - 6 = -8

y = -2

Using a linear function, it is found that the total rental charge will be of $159.7.

-----------

A linear function has the following format:

[tex]y = mx + b[/tex]

In which:

-----------

Thus, the linear function for the charge y in function of the number of miles x is:

[tex]y(x) = 0.16x + 52.50[/tex]

-----------

[tex]y(670) = 0.16(670) + 52.50 = 159.7[/tex]

The total cost of her trip will be of $159.7.

Answer:

C

Step-by-step explanation:

just put the value of f in the place of the x in g

Answer:

x = 20

y = 26

Step-by-step explanation:

40 and 2x are vertical angles, so they're equal to each other.

40 = 2x

Divide both sides by 2

x = 20

We see that 40 and 5y + 10 are a linear pair, which means they add up to 180.

5y + 10 + 40 = 180

5y + 50 = 180

5y = 130

y = 26

Ratios are used to show proportions of related quantities.

The ratio table equivalent to $10 per 15 tickets is:

[tex]\begin{array}{cc}{Amount}&{Tickets}&10&15&20&30&30&45&40&60\end{array}[/tex]

Given that:

Ratio = $10 per 15 tickets

Using proper notation, we have:

[tex]Ratio = 10:15[/tex]

To generate a ratio table, we simply multiply or divide each part of the ratio by the same unit.

For instance,

Multiply by 2

[tex]Ratio = 20:30[/tex]

Divide the original ratio by 5

[tex]Ratio = 2:3[/tex]

A possible ratio table is:

[tex]\begin{array}{cc}{Amount}&{Tickets}&10&15&20&30&30&45&40&60\end{array}[/tex]

The additive structure

From the above table, we can see that as the amount (x) increases by 10 units, the number of tickets (y) increases by 15 units.

So, the additive structure of the above table is:

[tex](x,y) \to (x_i+10,y_i + 15)[/tex]

The multiplicative structure

The multiplicative structure simply implies that the amount (x) and the number of tickets (y) be multiplied by the same unit.

So, the multiplicative structure of the above table is:

[tex](x,y) \to n(x_i,y_i)[/tex]

Answer:

6x² + 15

6

Step-by-step explanation:

Let the number be x.

"the square of a number"

x²

"the product of 6 and the square of a number"

6x²

"the product of 6 and the square of a number plus 15"

6x² + 15

The coefficient is the number that multiplies the variable, so it is 6.

The expression that can represent the given statement is 6x²+15, while the value of the coefficient is equal to 6.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Let the unknown number be represented by x. Therefore, the given statement can be broken down and written as shown below,

1. "the product of 6 and the square of a number"

        6x²

2. "the product of 6 and the square of a number plus 15"

        6x² + 15

Thus, the expression that can represent the given statement is 6x²+15.

Now, the coefficient of the expression is the number that is in multiplication with the unknown variable, therefore, x in this case. Thus, the value of the coefficient is 6.

Hence, the expression that can represent the given statement is 6x²+15, while the value of the coefficient is equal to 6.

Answer: four blows of hammer

Step-by-step explanation:

The first blow of hammer drove the 3cm nail into wood by 1.25cm leaving 1.75cm of the nail

3/5 or 0.6cm of the nail was also driven into wood by the second blow of hammer leaving 0.7cm of the nail

The third is also drove 0.6cm of the nail in leaving 0.1cm

since 0.1cm is not up to 0.7cm,it will definitely be driven in completely by the fourth blow of hammer.

The leftmost line segment has a domain of -4 ≤ x < -1, or [-4, 1).

The central line segment has a domain of -1 ≤ x ≤ 2, or [-1, 2].

The rightmost line segment has a domain of 2 < x ≤ 5, or (2, 5].

Overall, this function has a domain of

[-4, 1) U [-1, 2] U (2, 5]

(where U means "union" in the set-theoretic notion)

But this also simplifies to the interval [-4, 5].

These correspond to the first and last choices.

Answer:

Sand: 21 parts.

Lime : 14 parts.

Cement: 7 parts.

Step-by-step explanation:

The number of parts is 3 + 2 + 1 = 6.

So for 42 parts we need:

Sand: 3/6 * 42 = 1/2 * 42 = 21.

Lime:  2/6 * 42 = 1/3 * 42 = 14,

Cement: 1/6 * 42 = 7.
