Given:

The total number of pets can be represented by the expression [tex]y+y+y+y[/tex].

To find:

The expression which is equivalent to the expression for the total number of pets.

Solution:

The expression for the total number of pets is

[tex]y+y+y+y[/tex]

On adding these value, we get

[tex]y+y+y+y=4y[/tex]

Therefore, the expression 4y is equivalent to the given expression for the total number of pets.

Answer:

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:

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.

Answer:

Slope=. - 5

Step-by-step explanation:

[tex]slope = \frac{y1 - y2}{x1 - x2 } = \frac{3 - ( - 2)}{9 - 10} = \frac{5}{ - 1 } = - 5[/tex]

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:

  (-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).

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:

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:

[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]
