I believe it’s A because if it is perpendicular you would have to flip 6X and change the sign so therefore it would be A. In slope intercept form it would be y=-6x+1.
Answer:
1) Linear
2) Two (2 Terms means it is a Binomial)
3) 1/7
4) -x
5) -1 (-x = -1x)
The new mixture has a total volume of 5 L + 9 L = 14 L.
70% of the 5 L alcohol solution is alcohol, so that it contributed 3.5 L of alcohol to the mixture. The pure water contributed no alcohol. So in the mixture, the concentration of alcohol is
3.5 L / 14 L = 0.25, or 25%
Answer: r = -5/18
Step-by-step explanation: You solve -3(1+6r)+12=14
-3-18r+12=14 (When distributed)
-18r+9=14
-18r=5
r=-5/18
