Answer:

-24

Step-by-step explanation:

f(4) = 6

f(-4*4) = -4 * 6

-4*6

-24

9514 1404 393

Answer:

  (-1, 0)

Step-by-step explanation:

We want the point (4x, f(4x)) to match (-4, 0). We already know that f(-4) = 0, so we want 4x = -4.

  4x = -4

  x = -1 . . . . divide by 4

The desired point is (-1, 0).

_____

Comment on f(4x)

The attached graph shows that f(4x) represents a horizontal compression of the graph of f(x) by a factor of 4. The point on f(4x) with the same y-value, the corresponding point requested by this question, is shown to be (-1, 0).

Complete question is;

An ordinary deck of playing cards has 52 cards. There are four suits

-spades, hearts, diamonds, and clubs

-with 13 cards in each suit.

Spades and clubs are black; hearts and diamonds are red. One of these cards is selected at random. Let A denote the event that a red card is chosen.

Find the probability that a red card is chosen, and express your answer in probability notation.

Answer:

P(A) = 0.5

Step-by-step explanation:

We are told that the ordinary deck of playing cards has 52 cards.

Now, there are four suits

-spades, hearts, diamonds, and clubs

-with 13 cards in each suit.

Now, in a standard set of playing cards, there are 13 black spades and 13 black clubs as well as 13 red hearts and 13 red diamonds

Thus;

Number of red cards = 13 + 13

Thus;

Number of red cards = 26

Since, A denotes the event that red card is chosen.

This means that probability of choosing a red card is;

P(A) = number of red cards/total number in a deck of cards

P(A) = 26/52

P(A) = 0.5

Answer:

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

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

[tex]\frac{y-1}{2}[/tex] = x

Change y back into terms of x with x = [tex]f^{-1}[/tex](x) , thus

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

Answer:

B. y=1/4x-2

Step-by-step explanation:

The -2 in this equation represents the y value. The graph passes through -2 on the y axis, so you automatically cancel out the rest of the answers.

Option B is correct, y=1/4x - 2 is the function which  best represented by the given graph.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The line is passing through the points (0, -2) and (4, -1)

Let us find the slope m.

m = -1-(-2)/4

=1/4

So slope is 1/4

Now let us find the y intercept

-2=1/4(0)+b

-2=b

So equation will be y=1/4x-2

Hence, Option B is correct, y=1/4x - 2 is the function which  best represented by the given graph.

the answer is b because 7.20 / 4/5 that's her pay per hour

Answer:

D

Step-by-step explanation:

7.20 per 1/4 of an hour divided by 4 (to find the rate of one fifth of an hour)

is 1.8.

1.8 x 5 (to find the amount per hour) is 9.

$9 per hour.

Answer: There are 25 crates and 15 boxes in the truck when it is full.

Step-by-step explanation:

Let c= Number of crates , b= Number of boxes.

As per given,

[tex]c+b = 40[/tex]     (i)

[tex]3c=5b\\\\\Rightarow\ c=\dfrac{5b}{3}[/tex]        (ii)

Put value of c from (ii) in (i)

[tex]\dfrac{5b}{3}+b = 40\\\\\Rightarrow\ \dfrac{5b+3b}{3}=40\\\\\Rightarrow\ \dfrac{8b}{3}=40\\\\\Rightarrow\ 8b=3\times40\\\\\Rightarrow\ 8b=120\\\\\Rightarrow\ b=\dfrac{120}{8}=15[/tex]

put value of b in (ii),

[tex]c=\dfrac{5\times15}{3}=5\times5=25[/tex]

Hence, there are 25 crates and 15 boxes in the truck when it is full.

25 boxes 15 crates

We would get this solution by adding up the two sides comparing the ratios, hence: we get room for 3 crates for every 5 boxes that we can hold in the truck.

A ratio is an ordered pair of numbers a and b, written a:b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. hence, if there is 3 crates and 5 boxes you could write the ratio as: 3 : 5 (for every 3 crates there are 5 boxes) 3 / 5 are boys and 5 / 3 are crates.

Answer:

$8

Step-by-step explanation:

5x / 5 = x

40 / 5 = 8

Marisa’s mother contribution was $8 each month.

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Given that, Marisa’s savings account can be represented by the expression 5x+40. Marisa saved the same amount x each month for a period of 5 months. Her mother contributed an additional amount each month to Marisa’s savings account.

The amount in Marisa's account after 5 months = 5x + 40

She has saved $x each month for 5 months, therefore, her saving = 5x

Her mother given her an additional amount each month which is here shown by 40,

Since, if in 5 months it became 40, therefore, each month mother gave her = 40 / 5 = 8

Hence, Marisa’s mother contribution was $8 each month.

Answer:

96 calories per cup

384 calories in 4 cups

Step-by-step explanation:

In this scenario, we can use the rule of three to calculate the number of calories in a single cup like so...

72 calories   <==========>   [tex]\frac{3}{4} cup[/tex]  or 0.75 cup

 x  calories   <==========>  1 cup

(1 * 72) / 0.75 = 96 calories

Now we see that there are a total of 96 calories per cup of cereal. In order to find the total amount of calories in 4 cups of cereal, we simply need to multiply the number of calories per cup by 4, like so...

96 * 4 = 384 calories

There are a total of 384 calories in 4 cups of cereal.

Answer:

0.89, 23/25, 93%

Step-by-step explanation:

1. Convert 23/25 to a decimal: 0.92; and then a percent: 92%

2. Convert 0.89 to a percent: 89%

3. Now, we can order these from least to greatest. In order they would obviously be 89, 92, and 93 percent.

Answer:

70%

Step-by-step explanation:

Given that:

Initial water level in the tank at noon = 10 cm

After several hours, water level = 3 cm

To find the percentage change in the water in the tank, we can use the following formula:

[tex]Percentage\ Change = \dfrac{Final\ Value - Initial\ Value }{Initial\ Value}\times 100[/tex]

Here, Final Value = 3 cm

Initial Value = 10 cm

Putting the values in the formula:

[tex]Percentage\ Change = \dfrac{3 - 10 }{10}\times 100\\\Rightarrow Percentage\ Change = -70\%[/tex]

Here, negative value, means there is a decrease in the final value from the initial value.

Therefore, the answer is 70% decrease.
