Answer:

10x+40

Step-by-step explanation:

To solve you must follow these steps:

1. Multiply the outside (5) by the first number on the inside (2x) and you get 10x

2. Multiply the outside (5) by the second number on the inside of the parenthesis (8) and you get 40

3. You are left with 10x and 40, so your answer is 10x+40

Hope this makes sense, have a wonderful day!

Answer: 10x+40

This is because you will divide 5 by 2x and the 5 by 8 so once you divided your answer should look like 10x+40

Bus A travels according to the function y = 125/5x where y is distance traveled in miles and x is time in hours. Bus B travels a

Yuki888 [10]

Answer:

Bus B travel faster

Step-by-step explanation:

The graph of the question in the attached figure

we know that

the linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

x ---> is the time in hours

y ---> is the distance in miles

In this problem we have

Bus A

$y=\frac{125}{5}x$

The slope of the linear equation represent the speed of the bus

The speed of bus A is

$\frac{125}{5}=25\ miles/hour$

Bus B

Find the slope

take two points from the graph

(0,0) and (3,200)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute

$m=\frac{200-0}{3-0}$

$m=66.67\ \frac{miles}{hour}$

Compare the slope Bus A with the slope Bus B

$66.67\ \frac{miles}{hour} > 25\ \frac{miles}{hour}$

therefore

Bus B travel faster

Ber [7]

Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.
