Answer:

13. 0

14. 4

15. 0

*12. 10

Step-by-step explanation:

Given values of each variable:

n = 2

q = -1.5

r = -3

v = -8

w = 4.5

x = 4

Since all variables' values are given, the process of simplification is simple:

13:

|-2x + 5n| + (n-x) First, plug in all known values.

|-2(4) + 5(2)| + (2 - 4) Simplify the expressions in each of the parentheses.

|-8 + 10| + (-2) Add -- Addition of a negative is subtraction.

|2| - 2 The absolute value of 2 is 2.

2 - 2 Subtract.

14:

4w - |2r + v| First, plug in all known values.

4(4.5) - |2(-3) + (-8)| Simplify the expressions in each of the parentheses.

18 - |-6 - 8| Subtract the values in the parentheses.

18 - |-14| The absolute value of -14 is 14.

18 - 14 Subtract.

15:

3|w - n| - 5|q - r| First, distribute the 3 and 5.

|3w - 3n| - |5q - 5r| Plug in all known values.

|3(4.5) - 3(2)| - |5(-1.5) - 5(-3)| Distribute--Subtraction of a negative is addition.

|13.5 - 6| - |-7.5 + 15| Simplify the expressions in each of the parentheses.

|7.5| - |7.5| The absolute value of 7.5 is 7.5.

7.5 - 7.5 Subtract.

8. - 11. are correct. However, 12. is 10 because you need to distribute before simplifying what's in the parentheses.

The total operating cost to run the organic strawberry farm varies directly with its number of acres. What is the constant of va

kow [346]

Answer:

$16\ acres$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the number of acres

y ---> total operating costs

we have the ordered pair (20,551,520)

For x=20 acres, y=$551,520

Find the value of the constant of proportionality k

$k=\frac{y}{x}$

substitute the values of x and y

$k=\frac{551,520}{20}=\$27,576\ per\ acre$

The linear equation is equal to

$y=27,576x$

Find out how many acres are on a farm with a total operating cost of $441,216

For y=$441,216

substitute in the linear equation the value of y and solve for x

$441,216=27,576x$

$x=441,216/27,576$

$x=16\ acres$

Find the slope and use the point to write an equation of the line in point slope form.

Ainat [17]

Answer:

y - 3 = - 1/4(x + 2)

Step-by-step explanation:

m = - 1/4

Point = (-2,3)

y-intercept = 3 - (- 1/4) (-2)

= 3 - 1/2 = 5/2

y = - 1/4x + 5/2

Sav [38]

Simplifying
5y + -2 = 4y + 7

Reorder the terms:
-2 + 5y = 4y + 7

Reorder the terms:
-2 + 5y = 7 + 4y

Solving
-2 + 5y = 7 + 4y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-4y' to each side of the equation.
-2 + 5y + -4y = 7 + 4y + -4y

Combine like terms: 5y + -4y = 1y
-2 + 1y = 7 + 4y + -4y

Combine like terms: 4y + -4y = 0
-2 + 1y = 7 + 0
-2 + 1y = 7

Add '2' to each side of the equation.
-2 + 2 + 1y = 7 + 2

Combine like terms: -2 + 2 = 0
0 + 1y = 7 + 2
1y = 7 + 2

Combine like terms: 7 + 2 = 9
1y = 9

Divide each side by '1'.
y = 9

Simplifying
y = 9
