Two bicyclists are 7/8 of the way through a mile long tunnel when a train approaches the closer end at 40 mph. The riders take o
Anastaziya [24]

Answer:

the cyclists rode at 35 mph

Step-by-step explanation:

Assuming that the cyclists stopped, and accelerated instantaneously at the same speed than before but in opposite direction , then

distance= speed*time

since the cyclists and the train reaches the end of the tunnel at the same time and denoting L as the length of the tunnel :

time = distance covered by cyclists / speed of cyclists = distance covered by train / speed of the train

thus denoting v as the speed of the cyclists :

7/8*L / v = L / 40 mph

v = 7/8 * 40 mph = 35 mph

v= 35 mph

thus the cyclists rode at 35 mph

which statement best describes a line in slope-intercept form when the coefficient of the coefficient of the x term is positive​
lys-0071 [83]

Answer:

The line will be going 'uphill' from left to right

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

y=mx+b

where m is the slope

b is the y-intercept

If the coefficient of the x-term is positive

then

the slope is positive

therefore

If the values of x increases, the values of y increases

If the values of x decreases, the values of y decreases

The line will be going 'uphill' from left to right
