C is the answer ! Hope it helps
Answer:
1. x=21.8 2. x-= -103
Step-by-step explanation:
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
Answer:
-1
Step-by-step explanation:
f(x) = x^2-6x +4
[a,b] = [1,4]
The Average rate of change =
= -1
