With each gallon you need 11 gallons with 2 parts red 9 parts yellow and since 11x4= 44 you need to do this 4 times
4x2(red)= 8
4x9(yellow)=36
36+8=44
basically 8 gallons of red
i hope this made sense
Answer:
Both
and
are solutions to the system.
Step-by-step explanation:
In order to determine whether the two given points represent solutions to our system of equations, we must "plug" thos points into both equations and check that the equality remains valid.
Step 1: Plug
into ![y=x+8](https://tex.z-dn.net/?f=y%3Dx%2B8)
![(6) = (-2)+8 = 6](https://tex.z-dn.net/?f=%286%29%20%3D%20%28-2%29%2B8%20%3D%206)
The solution verifies the equation.
Step 2: Plug
into ![2y=x^2 + 8](https://tex.z-dn.net/?f=2y%3Dx%5E2%20%2B%208)
![2(6) = (-2)^2+8=4+8=12](https://tex.z-dn.net/?f=2%286%29%20%3D%20%28-2%29%5E2%2B8%3D4%2B8%3D12)
The solution verifies both equations. Therefore,
is a solution to this system.
Now we must check if the second point is also valid.
Step 3: Plug
into ![y=x+8](https://tex.z-dn.net/?f=y%3Dx%2B8)
![(12) = (4)+8 = 12](https://tex.z-dn.net/?f=%2812%29%20%3D%20%284%29%2B8%20%3D%2012)
Step 4: Plug
into ![2y=x^2 + 8](https://tex.z-dn.net/?f=2y%3Dx%5E2%20%2B%208)
![2(12) = (4)^2+8=16+8=24](https://tex.z-dn.net/?f=2%2812%29%20%3D%20%284%29%5E2%2B8%3D16%2B8%3D24)
The solution verifies both equations. Therefore,
is another solution to this system.
It is a function because in a function the x's do not repeat. So since there are no two numbers in the x column that are the same, yes it is a function.
Answer:
£ 12,150
Step-by-step explanation:
Marked price of bicycle = £ 12500
Rebate = 10%
Amount of rebate = 12500*10/100 = £1250
Rebated price = 12500 - 1250 = £ 11,250
Tax = 8%
Amount of tax = 11250*8/100 = £ 900
Total amount paid for bicycle = Rebated price + amount of tax
= £ 11,250 + £ 900
= £ 12,150
The answer is 40 square root of 6.
