Answer/Step-by-step explanation:
17. Slope = rise/run
rise = 5
run = 7
Slope = -⁵/7
18. Slope = rise/run
rise = 4
run = 4
Slope = -⁴/4 = -1
19. Slope = rise/run
rise = 3
run = 5
Slope = -⅗
20. Slope = rise/run
rise = 4
run = 1
Slope = -⁴/1 = -4
To find the cross product, you can set this up as a proportion. Please see the attached paper for one of the proportions you could use.
You would then multiply the numbers that are diagonal from each other.
You would have 21(8) = 12x or
168=12x.
The length of the line segment with endpoints at (0, 3) and (-6, -5) is 10 units
<h3>What is an equation?</h3>
An equation shows the relationship between two or more numbers and variables.
The distance between two points A(x₁, y₁) and B(x₂, y₂) on the coordinate plane is:

The line segment have endpoints at (0, 3) and (-6, -5). Hence:
Length = √[(-5-3)² + (-6 - 0)²] = √(8² + 6²) = √100 = 10
The length of the line segment is 10 units

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.
