1. Calculate the slope of Graph D. Explain or show your reasoning
2. Calculate the slope of Graph E. What situation could the graph represent
3. On the blank grid , draw a line that passes through the indicated point and has the slope -2.
Answer:
Step-by-step explanation:
1). Slope of a line shown on the graph will be,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-4}{1}[/tex]
= -4
2). Slope of the given horizontal line can be determined by,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Since, rise of the given line is zero.
Therefore, slope of the given horizontal line will be 0.
3). Slope of the line passing through the indicated line = -2
Therefore, a line which has a rise = -2 and run = 1 can be drawn on the given blank grid (As attached).
Answer:
Step-by-step explanation:
1. -4. Explanations vary. Sample explanation: for each horizontal change of 1, the vertical change is -4, so the slope of the line is -4.
2. 0. Responses vary. Sample response: The amount of rainfall on a day with no rain.
3. A graph through the indicated point with a slope of -2.

Mrs. Robertson is carpeting her rectangular living room.
The room is 10 feet wide and 15 feet long. What is the
area to be carpeted?
Answer:
150 ft
Step-by-step explanation:
The formula for area is, height x width (h x w) or base x height (b x h)
10 feet is the base and 15 is the height, multiply those and you get 150
For the algebraic equation, select the property or properties that could be used to solve it.

A fish tank that holds 80 gallons of water is 55% full. How many gallons are
in the tank now? PLZ HELP
55% of the fish tank is 44 gallons.
Step-by-step explanation:To solve this, you turn the 55% into a decimal, by dividing it by 100.
55 ÷ 100 = 0.55
You then multiply the whole capacity (80) by 0.55
80 x 0.55 = 44 gallons

To see if it is possible, you will want to create an equation.
3(4x+2) = 6(2x+2)
As you can see, you will need to use the distributive property for this equation.
12x + 6 = 12x + 12
Remove 6 from both sides.
12x = 12x + 6
Divide 12 by both sides
x = x + 0.5
Because the answer wasn't x = x, the two plants won't ever be the same height. Even if you tried to subtract 0.5, you'd only get a negative 0.5 on the other side.
A middle school took all of its 6th grade students on a field trip to see a play at a theater that has 3100 seats. The students left 1395 seats vacant. What percentage of the seats in the theater were filled by the 6th graders on the trip?
Answer: 55% of the seats in the theater were filled by the 6th graders on the trip.
Step-by-step explanation:
Given: Total seats = 3100
Seats vacant= 1395
Seats occupied by 6th graders = 3100-1395 = 1705
The percentage of the seats in the theater were filled by the 6th graders on the trip = [tex]\dfrac{\text{Seats occupied by 6th graders}}{\text{Total seats}}\times100[/tex]
[tex]=\dfrac{1705}{3100}\times100\\\\= 55\%[/tex]
Hence, 55% of the seats in the theater were filled by the 6th graders on the trip.
Cecilia watched 1 2 of a movie in the morning, and she watched some more at night. By the end of the day, she still had 1 3 of the movie left to watch. How much of the movie did Cecilia watch at night?
Answer: 1/6 of the movie.
Step-by-step explanation:
First, she watches 1/2 of the movie.
This means that if the movie lasts N minutes, the time left is:
N - (1/2)*N = (1/2)*N.
Then she watches another part of the movie, let's call it as a*N, and after that, she has 1/3 of the movie left, we can write this situation as:
(1/2)*N - a*N = (1/3)*N
we can divide by N in both sides to get
(1/2) - a = (1/3)
(1/2) - (1/3) = a
3/6 - 2/6 = a
1/6 = a
So we can conclude that she watched 1/6 of the movie at night.
3x+4=9x+3 so what does x equal?
Answer:
x = 1/6
Step-by-step explanation:
6x = 1
x = 1/6
Answer:
x = 1/6
Step-by-step explanation:
3x + 4 = 9x + 3
collect ' like terms'
the smaller terms should be the ones crossing the = sign
4 - 3 = 9x - 3x
1 = 6x
x = 1/6

The owner where your work explains that you're paid $8/hour and receives a $25 bonus each month for being the manager. If the owner hands you a check for $250, How many hours did you work this month? Write an equation and solve.
Answer:
28.125 hours
Step-by-step explanation:
Amount of money paid per hour = $8
Bonus of being a manager = $25
Total amount of money paid = $250
To find:
Number of hours worked for this month?
Solution:
Let the number of hours worked = [tex]h[/tex] hours
Amount of money paid for [tex]h[/tex] hours = $8[tex]h[/tex]
As per question statement:
Bonus + Amount of money paid for [tex]h[/tex] hours = $250
[tex]25 + 8h = 250\\\Rightarrow 8h = 250 -25\\\Rightarrow 8h = 225\\\Rightarrow h =\dfrac{225}{8}\\\Rightarrow \bold{h = 28.125\ hours}[/tex]
Therefore, the answer is:
Number of hours worked = 28.125 hours

Step-by-step explanation:
A car rental offers two options for renting a car. Plan A costs $200 per week plus $0.35 for each mile driven during that week. Plan B costs $180 per week plus $0.55 for each mile driven that week. How many miles of driving would result in both plans costing the same amount for that week
Answer:
100 miles
Step-by-step explanation:
Two plans are being offered for the renting of cars.
Plan A:
Cost per week = $200
Cost for each mile = $0.35
Plan B:
Cost per week = $180
Cost for each mile = $0.55
To find:
Number of miles for which the cost is same ?
Solution:
Let the number of miles driven so that the cost becomes the same = [tex]m[/tex] miles
First of all, let us find the cost for each plan as per [tex]m[/tex] miles.
Cost as per plan A = Cost per week + Cost for [tex]m[/tex] miles = $200 + $0.35[tex]m[/tex]
Cost as per plan B = Cost per week + Cost for [tex]m[/tex] miles = $180 + $0.55[tex]m[/tex]
Now, putting both the costs equal to find the value of [tex]m[/tex]:
[tex]200 +0.35m = 180 +0.55m\\\Rightarrow 20 = 0.20m\\\Rightarrow m = \bold{100\ miles}[/tex]
Therefore, after 100 miles the cost from each plan will be the same.
