Answer:
Step-by-step explanation:
Again, let us begin by finding the equation of the line
The y-intercept is 0 and the slope is 1, so the equation of this line would be or just
We can see that the shaded region is ABOVE the line, so we would use a greater than (>) sign.
This as the line is shaded in, we must also include that line in the inequality. This means that we will instead use the sign.
This means that our answer would be
Answer:
32 weeks.
Step-by-step explanation:
Let w represent number of weeks.
We have been given that the new plan will have the office recycling 1 kilogram of paper each week. So kilograms of paper recycled in w weeks would be .
We are also told that Toby's office had already recycled 7 kilograms. So total kilogram of paper recycled in w weeks would be .
Since Toby's office has to recycle a total of 39 kilograms of paper, so we will equate 39 with paper recycled in w weeks as:
Therefore, it will take 32 weeks for Toby's office to recycle a total of 39 kilograms of paper.
