Answer:
y = -2x -3
Step-by-step explanation:
- the altitude trough F is a perpendicular line to the line DE
- find slope of line DE
D ( x2 = -5, y2 = -1); E (x1 = 3, y1 = 3)
slope m = (y2-y1) / (x2-x1) = (-1-3) / (-5-3) = -4/ -8 = 1/2
-find equation of the altitude trough F
lines that are perpendicular have the slope negative reciprocal (negative reciprocal of 1/2 is -2)
y= -2x +b , for point F(1, -5)
-5 = -2*1 +b, add 2 to both sides
-5 +2 = b, combine like terms
-3 =b
equation of the altitude trough F is y = -2x -3
Answer:
B
Step-by-step explanation:
An even number is a number divisible by 2 and be an integer. An example would be 4/2 = 2
An incorrect even number would be 5
5/2 = 2.5 which isn't odd or even because it isn't an integer.
Average speed = (distance final - distance initial)/(time final - time initial)
Average speed = (30-0)km /(100 -0)min = 3/10 km/min
3/10 km/min *60 min/1 h = 180/10 km/h= 18 km/h
1st page: it is the fourth answer, y is less than or equal to 12
2nd page: it is the second answer, m is less than or equal to 450
3rd page: it is the first answer, x > -3
4th page: it is the fourth answer, b is more than or equal to 500

<u>Step-by-step explanation:</u></h3>
A figure is given to us in which we can see two triangles one is ∆ MPL and other is ∆MPN .
<u>Figure</u><u> </u><u>:</u><u>-</u><u> </u>
Hence by SAS congruence condition ,
Hence by cpct ( Corresponding parts of congruent triangles ) we can say that , LM = NM = 11 units .
