Answer: Marcus's walking speed is 4 mph

Step-by-step explanation:

Let x represent Marcus's walking speed.

His speed on the bicycle is 6 mi/h faster than his walking speed. This means that his speed on the bicycle would be

x + 6

Time = distance/speed

Time spent by Marcus in walking 1 mile to the library is

1/x

Time spent by Marcus in bicycling 2.5 miles to the sporting good store is

2.5/(x + 6)

Since the time that he spends in walking to the library is about the same time that he spends in bicycling to the sporting good store, then

1/x = 2.5/(x + 6)

Cross multiplying, it becomes

1 × (x + 6) = 2.5 × x

x + 6 = 2.5x

2.5x - x = 6

1.5x = 6

x = 6/1.5 = 4

Taylor dropped a rubber ball from a height of 8 feet.The ball hit the ground after 1 second,bounced up to 5 feet in the next sec
Rzqust [24]

Answer:

The graph is constant in the interval [4,6]

Step-by-step explanation:

We are given that,

Taylor dropped a rubber ball from a height of 8 feet.

So, at time t= 0 sec, the ball is being thrown.

Now, the next events follows as below:

1. After a second, the ball hits the ground.

2. It bounces up to 5 feet in the next second.

3. The ball again hits the ground in the next second.

4. Now, the ball again jumps up to height 2.5 feet, when Taylor holds the ball for 2 seconds more.

So, we get the figure given below, we see that,

The graph is constant in the interval [4,6].

One week a computer store sold total of 36 computers and external drives. The revenue from these sales were $23490. If computers
yarga [219]

Answer:

X = 18

Y = 18

Step-by-step explanation:

first make two equation like

x + y = 36

1180x + 125y = 23490

from equation one we have

y = 36- x

put in second equation

1180x + 125 (36-x) = 23490

1180x + 4500-125x = 23490

1055x = 23490-4500

x = 18990/1055

x = 18

put this x value in equation 1 to find y value

18+ y = 36

y = 36-18

y = 18

Which system of equations is represented by the graph? rational graph with asymptotes of x equals 4 and y equals negative 1. Lin
nata0808 [166]

The points of intersection are (-2, -2) and (5, 5), so clearly y = x. This reduces the choices to the first and third ones.

Since x-4 is the denominator of all choices, its value at the point (5, 5) will be 1. Hence you need to find the choice that has a numerator of 5 when x=5.

The first choice has a numerator of -5-10 = -15, so that's not it.

The third choice has a numerator of -5+10 = 5, so that's the one you're looking for.

The best choice is the third one, ...

... y = negative x plus ten divided by the quantity x minus four , y = x
