Answer:
First graph's equation is: y=2/3x+3
Second graph's equation is: y=2/3x-1
Third graph's equation is: y=2/3x+1
Fourth graph's equation is: y=2/3x-3
Step-by-step explanation:
Well you didn't provide the equation so I can't give you the exact answer but I can tell you the equation for each graph and you can match that with the equation they gave you!
Here ya go:
The y intercept is where the line crosses the y axis(vertical axis)
The slope is rise/run (vertical/horizontal)
The first graph:
The line crosses the y axis at (0, 3)
To find the slope we need to take the (y) of one of the given coordinates and subtract the (y) of the other coordinate then divide that over (x) of one of the coordinates minus the (x) of the other coordinate.
5-1/3-(-3)
4/6
2/3 is our slope, apply that to slope-intercept formula (y=mx+b)
y=2/3x+3
The second graph:
The line crosses the y axis at (0, -1)
Do as we did with the first graph to find the slope.
1-(-3)/3-(-3)
4/6
2/3 is our slope
y=2/3x-1
The third graph:
The line crosses the y axis at (0, 1)
Find the slope
3-(-1)/3-(-3)
4/6
2/3 is our slope
y=2/3x+1
The fourth graph:
The line crosses the y axis at (0, -3)
Find the slope
-1-(-5)/3-(-3)
4/6
2/3
y=2/3x-3

What is the equation of the line that passes through the point (2,-6) and has a slope of -1?
Answers
Answer:
y = -x - 4
Step-by-step explanation:
Plug in the point and slope into the equation y = mx + b, and solve for b:
y = mx + b
-6 = -1(2) + b
-6 = -2 + b
-4 = b
Then, plug in b and the slope into y = mx + b
y = -1x - 4
y = -x - 4 is the equation of the line

Suppose 2,400 spectators attend at leas one game this soccer season. Use ther survey data to estimate the number of spectators who attended 5 or more games this season
Answers
Answer:
800 spectators
Step-by-step explanation:
Using the survey provided above, we can see that the survey population is a total of 150 spectators by adding up all of the spectators. Since only 50 spectators attended 5 or more games then that means that the percentage of the survey population that attended 5 or more games is ...
50 / 150 = 0.3333 or 33.33%
Therefore, if we are supposing that 2,400 spectators attended at least one game this season then we can multiply this population by the percentage of people who tend to attend 5 or more games in order to actually calculate the total number of people who will attend 5 or more games this season.
2,400 * 0.3333 = 800 spectators

3a+2b-a-3b
Answers
Answer:
Step-by-step explanation:2a-b
Answer:
2a-b
Step-by-step explanation:
We can start by grouping our A's and B's, while making sure to keep their individual signs.
For our A's, we get 3a-a and for our B's, we get 2b-3b.
When we simplify our A's, we get 2a and when we simplify our B's, we get -b.
After grouping them back together, you end up with 2a-b.

f(x) is y and x is x
The table is providing you with points
y-y over x-x gives you a slope of -5
Use the points and turn it into a point-slope equation and convert to y-intercept equation
y-15=-5(x+2)
y-15=-5x-10
y=-5x+5
So the y-intercept is 5 or (0,5)

At time t=0 hours, a tank contains 3000 litres of water. Water leaks from the tank. At the end of every hour there is x% less water in the tank than at the start of the hour. The volume of water, in litres, in the tank at time t hours is Vt. Given that Vt=KtV0 V2=2881.2 work out the value of k and the value of x.
Answers
Answer:
x = 2; K = 0.98
Step-by-step explanation:
At time, t = 0, Volume of Water = 3,000 litres
After t hours , the Volume of water in the tank = Vt
At the end of every hour there is a x% less water in the tank then at the start of the hour
After 1 hour, volume of water left Vt = V1
V1 = 3,000 - 3000 × (x/100)
V1 = 3,000 - 30x
After 2 hours, Volume of water left is V2
V2 = (3,000 - 30 x) - (3,000 - 30 x) × (x/100)
V2 = (3,000 - 30 x) - (3000x - 30x²)/100
V2 = {100(3000 - 30x) - x(3000 - 30x)} /100
V2 = {(3000 - 30x)(100 - x)}/100
Recall, V2 = 2881.2
Therefore
{(3000 - 30x)(100 - x)}/100 = 2881.2
(3000 - 30x)(100 - x) = 288120
300000 - 3000 x - 3000 x + 30 x² = 288120
30 x ² - 6000 x + 11880 = 0
Dividing both sides by 30
x² - 200 x + 396=0
Factorizing:
(x -198)(x-2) = 0
x = 198 or x = 2
Since the percentage by which the water reduces cannot be greater than 100, x = 2 is chosen.
Step 2: Solving for k
Given that Vt=KtV0
K = Vt/V0
At t = 1
V1 = 3000 - 30x
V1 = 3000 - 30 × 2
V1 = 3000 - 60
V1 = 2940
K = 2940/3000
K = 0.98
