Answer:
12
Step-by-step explanation:
4y - 2x
= 4(7) - 2(8)
= 28 - 16
= 12
Answer:
y=-2/3x+11
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(7-5)/(6-9)
m=2/-3
m=-2/3
y-y1=m(x-x1)
y-5=-2/3(x-9)
y=-2/3x+18/3+5
y=-2/3x+6+5
y=-2/3x+11
I'm going to use the slope formula which is
m = (y2 - y1)/(x2 - x1)
where (x1,y1) and (x2,y2) are the two points the line goes through
Slope of line PQ
m = (y2 - y1)/(x2 - x1)
m = (-6 - 8)/(-5 - (-7))
m = (-6 - 8)/(-5 + 7)
m = (-14)/(2)
m = -7
The slope of line PQ is -7
Slope of RS
m = (y2 - y1)/(x2 - x1)
m = (0 - (-5))/(-2 - 3)
m = (0 + 5)/(-2 - 3)
m = (5)/(-5)
m = -1
The slope of line RS is -1
Because the slopes are NOT equal (one is -7 and the other is -1), this means the lines are NOT parallel.

Answer: Choice B) No, the lines have unequal slopes
Answer:
approximately 3.16 repeated
Step-by-step explanation:
What is 7x5x4, it is 140 so the volume is 140in^3 its a pretty simple problem
