Answer:

Step-by-step explanation:

f(x) = -3x-6

slope of line is -3

parallel lines have the same slope

point-slope equation for line of slope -3 that passes through (6,-8):

y+8 = -3(x-6)

put equation into slope-intercept form:

y = -3x + 10

Answer:

y =  - 3x  + 10

Step-by-step explanation:

We are asked to find a line parallel to line f

- 3x - 6

and passes through 6,-8.

Parallel lines have the same slope so our new line will also has-3 as it slope

wo using the slope intercept form let update our equation so far.

Slope intercept is

y = mx + b

where m is the slope and b is the y intercept

plug in -3 for the slope since our new equation must be parallel.

y =  - 3x + b

Now plug 6 for x and -8 for y.

- 8 =  - 3(6) + b

- 8 =  - 18 + b

b = 10

Our equation is

y =  - 3x  + 10

Answer:

  • <em>The net change in how many bags are on the shelf, from the beginning of Tuesday to the end of Monday is -</em><u>2.</u>

Explanation:

The change in the number of bags any day is the number of bags is equal to the number of bags purchased to restock less the number of bags sold that day.

  • Change = bags purchased to restock - bags sold

At the end of <em>Tuesday</em>, the change is:

  • Restock:    6
  • Sales:        5
  • Change:    6 - 5 = 1    (note that this means that the number of bags increases by 1)

At the end of <em>Wednesday</em>, the change is:

  • Restock:    12
  • Sales:        8
  • Change:    12 - 8 = 4    (the number of bags increases by 4)

At the end of <em>Thursday</em>, the change is:

  • Restock:    12
  • Sales:        2
  • Change:    12 - 2 = 10    (the number of bags increases by 10)

At the end of <em>Friday</em>, the change is:

  • Restock:    18
  • Sales:        19
  • Change:    18 - 19 = - 1    (the number of bags decreases by 1).

At the end of <em>Saturday</em>, the change is:

  • Restock:    24
  • Sales:        22
  • Change:    24 - 22 = 2    (the number of bags increases by 2).

At the end of <em>Sunday</em>, the change is:

  • Restock:    0
  • Sales:        15
  • Change:    0 - 15 = - 15    (the number of bags decreases by 15).

At the end of <u>Monday</u>, the change is:

  • Restock:    0
  • Sales:        3
  • Change:    0 - 3 = - 3    (the number of bags decreases by 3).

The net change in how many bags are on the shelf, from the beginning of Tuesday to the end of Monday equals the algebraic sum of every change:

  • Net change = 1 + 4 + 10 + (-1) + 2 + (-15) + (-3)
  • Using associative property: (1 + 4 + 10 + 2) - (1 + 15 +3)
  • Simplifying: 17 - 19 = -2

<u>Conclusion</u>: the net change in how many bags are on the shelf, from the beginning of Tuesday to the end of Monday is -2, meaning that the number of bags, after taking into account all sales and restock, decreases by 2.

An aquarium holds 11.1 cubic feet of water and is 2.8 feet long and is 1.2 feet wide.what is the depth?
just olya [345]

Step-by-step explanation:

the volume of any cube or prism is

length × width × height (or depth)

11.1 = 2.8 × 1.2 × depth

depth = 11.1 / (2.8 × 1.2) = 11.1 / 3.36 = 3.303571429 ft

≈ 3.3 ft
