A train travels 4.4 miles in

Mathematics
1 answer:
Ugo [173]2 years ago
3 0

Answer:

63.8 miles

Step-by-step explanation:

If the train travels 4.4 miles in 4 minutes, then you have to divide 4.4/4 to find the miles the train travels per minute.

4.4/4 = 1.1

So, since the train travels 1.1 miles per minute, and we want to know how fast it travels in 58 minutes, we have to multiply 1.1 by 58. Since 1.1 is a decimal number, we have to multiply both sides by 10 to get 11x580.

11x580 = 5800+ 580 = 6380

Since we multiplied both numbers by 10, we have to divide 6380 by 100.

6380/100 = 63.8

So, the train travels 63.8 miles in 58 minutes.

If you apply the changes below to the absolute value parent function f(x)=lxl, what is the equation of the new function?
Snowcat [4.5K]

Answer:

f(x)=|x+4|+2

Step-by-step explanation:

The given absolute value function is

f(x)=|x|

This is the base or the parent function.

The transformation f(x)=|x+b|+c will shift the parent function b units to the left and c units up.

From the question, b=4 units and c=2 units.

The new equation is f(x)=|x+4|+2
