Ok, so to so to find gradient with two coordinates you can use this formulae.. m=y2-y1 over x2-x1. Example A=(4,3) and Q(8,5) 4 would be x1, 3 would be y1 , 8 would be x2 and 5 would be y2 put them in the formulae and work it out. its pretty easy after you put them in :)
Diagonals of a parallelogram bisect each other
or they intersect each other in the halfway
x+4=3y-11-------------------------equation1
2x-1=y-1-------------------------------equation2
mulitply equation 1 to 2
2x+8=6y-22-----------------------equation3
equation2 - equation3
-9=-5y +21
5y=30
y=6
then x= 3
now PT=2x-1=5
TR=y-1=5
ST=3y-11=7
TQ=x+4=3+4=7
5(-2a-8) < -9a + 4
Use distributive property on left side:
-10a -40 < -9a + 4
Add 40 to both sides
-10a < -9a + 44
Add 9a to both sides
-a < 44
Multiply both sides by -1 and reverse the inequality sign:
A > -44
Answer: a > -44
Answer:
C
Step-by-step explanation:
The triangle is reflected across the y-axis and moved down 3 units.
5 times something must equal 12
12/5 equals 2.4
w=2.4
