Answer: The x-intercept indicates that the entire pile of dirt will have been moved after 6 hours.

Step-by-step explanation:

Given: A function graphed models the volume of dirt y in cubic feet, remaining in the pile after x hours.

We can see from the graph that the slope of the line tells that the volume dirt is moving with respect to time and the equation of line could be in intercept form where y intercept tells the total maximum volume of dirt i.e. 450 cubic feet and x- intercept tells the entire volume of dirt had been moved after 6 hours.

A line has a slope of 2. It passes through the points (1, 2) and (3, y) . What is the value of y? y=

malfutka [58]

Answer:

Step-by-step explanation:

To solve this , we use the equation of finding a slope wig a line.

m = (y2 - y1)/(x2 - x1)

From the question, we know that:

y2 = y

x2 = 3

y1 = 2

x1 = 1

m = 2

Hence,

2= (y - 2)/(3 - 1)

2 = (y - 2)/2

4 = y - 2

y = 2 + 4 = 6

twice the sum of a number and 6 is equal to 3 times the difference of the number and 8. Find the number

Serhud [2]

In order to solve this problem, we must solve an equation.

First, we need to define our unknown.

Let's call our number "n".

So, the sum of the number and 6 is the same as saying n+6

Then we need to multiply it by 2 (since it's twice the sum)

2(n+6)

This whole thing is equal to three times of the difference of the number and 8

n-8 is equal to the difference between the number and 8, then we need to multiply it by three.

3(n-8)

now, we set both sides equal and solve

$2(n+6)=3(n-8)\\2n+12=3(n-8)\\2n+12=3n-24\\12=n-24\\36=n$

The number is 36
