Answer:

13/3 =x

Step-by-step explanation:

f(x)=3x+2

Let f(x) = 15

15 =3x+2

Subtract 2 from each side

15-2 =3x+2-2

13 = 3x

Divide each side by 3

13/3 = 3x/3

13/3 =x

Answer:

Step-by-step explanation:

perimeter (p) = 2L + 2W

where P = 230 ft.

W = 2/3L

plugin values into the formula:

230 = 2L + 2(2L/3)

230 = 2L + 4/3L

230 = 10/3L

L = 690/10

L = 69

W = 2/3L

W = (2/3) 69

W = 46

P = 2(69) + 2(46)

P = 230 ft.

therefore,

the dimensions of the rectangular garden:

length = 69 ft

width = 46 ft.

Answer:

The answer is (2, 0)

Step-by-step explanation:

Plug in the (x, y) values for both inequalities from each answer choice. When you do that, only one option, (2, 0), will result in a false statement.

Answer:

Expression will be 10(x - 6).

Step-by-step explanation:

Let the given number is x.

Difference of this number and 6 will be represented by

(x - 6)

Then ten times the difference of this number and 6 will be represented by

10(x - 6)

Therefore, the statement " ten times the difference of a number and six " will be represented  by the expression 10(x - 6)

the answer happpens to be -7/3

Answer: 3.9

explanation: It's right

Assuming you know the mean (mu) and the standard deviation (sigma), you would use the raw score (x) to get the z score through this formula

z = (x-mu)/sigma

If you get a positive z value, then the raw score is above the mean. If z is negative, then the raw score is below the mean.

The absolute value of z tells us how far away from the mean we are in terms of standard deviation.

Eg: z = -3 leads to |z| = |-3| = 3, so we're 3 standard deviations below the mean.

Answer:

Range of the function is:

{55.25, 100.50, 145.75, 191.00, 236.25, 281.50}

Step-by-step explanation:

Given that:

Seating capacity of the car = 6

Entrance fee per person = $45.25

Parking fee per car = $10

Leah is accompanied by [tex]x[/tex] friends.

So, the total cost can be modeled as the following linear function:

[tex]y=45.25x+10[/tex]

Now, the value of [tex]x[/tex] i.e. number of friends going with Leah can be any of the following:

0, 1, 2, 3, 4 or 5 (because maximum capacity of the car is 6).

Leah is also going.

So, total number of people can be 1, 2, 3, 4, 5 or 6.

Therefore, the table of [tex]x, y[/tex] can be:

[tex]\begin{center}\begin{tabular}{ c c}x & y \\ 1 & 55.25 \\ 2 & 100.50 \\ 3 & 145.75 \\ 4 & 191 \\ 5 & 236.5 \\ 6 & 281.50 \\\end{tabular}\end{center}[/tex]

Here, the value of [tex]y[/tex] is nothing but the range of the function.

Therefore, the range of the linear function is:

{55.25, 100.50, 145.75, 191.00, 236.25, 281.50}

Answer:

1 < x < 6

Step-by-step explanation:

6 < x + 5 < 11

You want x alone, and 5 is being added to x, so subtract 5 from all three sides of the compound inequality.

6 - 5 < x + 5 - 5 < 11 - 5

1 < x < 6

Answer:

1<x<6
