Answer:
Since the slopes of the two equations are equivalent, the basketballs' paths are parallel.
Step-by-step explanation:
Remember that:
- Two lines are parallel if their slopes are equivalent.
- Two lines are perpendicular if their slopes are negative reciprocals of each other.
- And two lines are neither if neither of the two cases above apply.
So, let's find the slope of each equation.
The first basketball is modeled by:
![\displaystyle 3x+4y=12](https://tex.z-dn.net/?f=%5Cdisplaystyle%203x%2B4y%3D12)
We can convert this into slope-intercept form. Subtract 3<em>x</em> from both sides:
![4y=-3x+12](https://tex.z-dn.net/?f=4y%3D-3x%2B12)
And divide both sides by four:
![\displaystyle y=-\frac{3}{4}x+3](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%3D-%5Cfrac%7B3%7D%7B4%7Dx%2B3)
So, the slope of the first basketball is -3/4.
The second basketball is modeled by:
![-6x-8y=24](https://tex.z-dn.net/?f=-6x-8y%3D24)
Again, let's convert this into slope-intercept form. Add 6<em>x</em> to both sides:
![-8y=6x+24](https://tex.z-dn.net/?f=-8y%3D6x%2B24)
And divide both sides by negative eight:
![\displaystyle y=-\frac{3}{4}x-3](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%3D-%5Cfrac%7B3%7D%7B4%7Dx-3)
So, the slope of the second basketball is also -3/4.
Since the slopes of the two equations are equivalent, the basketballs' paths are parallel.
Answer:
8x-4
Step-by-step explanation:
(3x-5)+(5x+1)
=3x-5+5x+1
=8x-4
It looks like it goes through (0,-3) and (1,2), so the gradient is (change in y)/(change in x) ->
(-3-2)/(0-1) = 5
So y=5x+b
Then as we know it passes the y axis at (0,-3) so b= -3
So we have y=5x-3
Answer:
Where is the function shown below?
Step-by-step explanation:
Answer:
31.25
Step-by-step explanation:
25 is 80% of the original. Divide 25 by 8 to get 10%. This is 3.125. Multiply this by 10 to get 100%, and therefore the full amount.
