1)
We know that each coordinate (x,y) must therefore multiply to equal 7. The only numbers that multiply to 7 are 7 and 1, so B) is the correct answer.
2)
For this one, just plug in the coordinates they give you for x and y and see if either one works:
So the first one is a solution. Now plug in the second one:
Therefore, the first is a solution and the second isn't making C) the correct answer.
3)
For this one, just plug in the ordered pairs they give you and see which ones end up working:
A) and B) are the only ones that work out, so those are the correct answers.
Answer:
Original slope: 3/4
Perpendicular slope: 4/3
Step-by-step explanation:
Find the original slope by using rise over run, then flip the original slope which finds your perpendicular slope.
The first train will be 5 hours and 25 minutes
The second would be 2 hours and 35 minutes
Okay, it's the equation to how find area any other way. A=L×W
This means *picture above*
So then you count over each line meaning 1.
This means L=9 and a 1/2. Since its in between the 2 an 3 on the x-axis.
Now for W or width. It equals 3 since you can count 2 lines and one either ends of the polygon is 1/2 each this creates one when added together.
All you do from there is multiply 9 and 3. This should give you A=area.
