Answer:
k = 9.
Step-by-step explanation:
2x + 3y -8=0
3y = -2x + 8
y = -2/3 x + 8/3
So the slope of this line is -2/3.
Therefore the slope of a line perpendicular to the above is -1 /-2/3
= 3/2.
kx - 6y = 9
6y = kx - 9
y = k/6x - 3/2
But the slope is 3/2,
So k/6 = 3/2
2k = 18
k = 9.
Answer:
10 1/4 - 2 2/4 = 37/4
Step-by-step explanation:
- 10 1/4 - 2 1/2
- 10*4+1/4 = 41/4
- (41/4) - 1 = 37/4
That answer!

Answer:
59 feet per second
Step-by-step explanation:
- (40m)(5280ft)=211,200 ft/hr
- (211,200 ft/hr )=(211,200ft/3600s)
- 58.7 ft/s
