Step-by-step explanation:
side A+(8x+2)=x²+12x
side A=x²+12x-8x-2
side A=x²+4x-2
side B+(x-6)=2x²-4
side B=2x²-4-x+6
side B=2x²-x+2
12 divided by 5/6 equals 14 2/5
This is your equation
4/3 x 3.14 x
8 ^{3}
4/3 x
3.14 x 5124/3 x 1607.68
2143.57 (I also got 2144.66 if the first one doesn't work)
Answer:
Jill's rate of running = 4.667 miles/hr
Step-by-step explanation:
Let's say that rate of running = x miles/hr
so rate of biking = (x + 10) miles / hr
Time of running = rate of running / distance of running = x/6
Time of biking = rate of biking/distance of biking = (x+10)/12
Total time of cycling and biking = Time of running + Time of biking
Given that total time of cycling and biking = 2 hrs
⇒ 2 = (x/6) + ((x+10)/12)
⇒ 2 = (2x+x + 10)/12
⇒ 2 × 12 = 3x + 10
⇒24 - 10 = 3x
⇒x = 14/3 =4.667 miles/hr
Hence Jill's rate of running = 4.667 miles/hr
Y = -x - 2.5
explanation: the x axis is in the negative side, and the y axis as well, plotted at 2.5 down making it negative as well
