For the given vectors 
and 
The dot product of vectors a and b is defined as = 
So, 
= -16+12
= -4
Answer: 4, -1, [see if you can figure it out]
Step-by-step explanation:
Answer:
y=-4x+5
Step-by-step explanation:
the line goes down 4 for every 1 that x changes. the line crosses the y axis at 5.
(this might not be accurate, I can't really see if the line is on the exact point or not)
Opposite angles of parallelogram are equal.
sum of interior angles of parallelogram is 360 degrees.
Therefore,
A + B + C + D = 360
x + 145 + x + 145 = 360
x = 35
Therefore angle C is 35 degrees
Answer:
A number <u>X</u>
