What value of b will Cause the system to have an infinite number of solutions y=6x-b -3x+1/2y=-3

2 answers:

7 0

The first equation is

y = 6x - b

For the system to have an infinite number of solutions, both equations must be the same equation.

Solve the second equation for y.

-3x + 1/2 y = -3

1/2 y = 3x - 3

y = 6x - 6

Compare this with the first equation,

y = 6x - b

That means b = 6

a biker must circle a 12 mile track twice. His average speed must be 60mph. On his first lap he averaged 50 mph. How fast must h

liq [111]

Answer:

75 mph

Step-by-step explanation:

A biker must circle a 12-mile track twice. His average speed must be 60 mph.

So, the average time required to cover the distance is $\frac{2 \times 12}{60} = 0.4$ hours.

Now, on his first lap, he averaged 50 mph.

So, he covered this 12 miles track in $\frac{12}{50} = 0.24$ hours.

Hence, he has to cover the next 12 miles track in (0.4 - 0.24) = 0.16 hours.

Therefore, his average speed in the second round must be $\frac{12}{0.16} = 75$ mph to qualify. (Answer)
