Answer:
y=-3/4x+3
Step-by-step explanation:
subtract 3x from both sides: 4y=-3x+12
Divide both sides by 4: y=-3/4y+3
Step-by-step explanation:
let X = speed of slow bicycle rider
2x=speed of fast bicycle rider
3(x+2x)=72
X=8mph(slowest bicycle rider)
2x=16mph(fastest bicycle rider)
Is it to the 4th power and the second power if so it is:
(
x
^2
−
3
)
^2
Assuming the order does not matter, you want the number of combinations of 9 things taken 5 at a time. The combinations can be shown as C(9,5), 9C5.
C(9, 5) =
9/5(9-5) =
9*8*7*6*5 / 5*4
The 5 terms cancel.
9*8*7*6 / 4*3*2 =
9*7*2 =
126
The above change is because 4*2 cancels the 8 in the numerator and 6/3 = 2
Therefore, the solution is 126.
The additive inverse of 1/3 is 3/1.
Hope this helps you!
