Answer:
y = 4x+ 3
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = 4x+ 3
You need the distance formula to figure this out. The coordinates for point D are (-5, 1), the coordinates for point E are (-2, 3), and the coordinates for point F are (-3, -2). For the distance or length of DE, the formula looks like this:
which simplifies a bit down to
which is
which of course is
so DE = 25. Moving on to EF:
which simplifies to
which is to say that
. We do the same for FD:
which simplifies a bit to
which is to say that the length of FD is
. None of the lengths of the sides are the same, so this is a scalene triangle. Last choice given above.
Answer:
The range is 80.
Step-by-step explanation:
You just find the biggest and the smallest number and find the difference between the biggest and the smallest number. In this case, 191-111 is 80.
So you have 5.36
that is 5 wholes and 0.36
0.36 can be written on a fraction of 36/100
simplify it to 9/25
Now you have the mixed number
5 9/25 or to write it into an improper fraction... multiply 25 * 5 then add 9, that is 134/25.
Hope this helps
