A) If 9 students sharpen 18 pencils in 2 minutes,Then if the time is halved, it will take twice as many men to sharpen 18 pencils.Hence it will take 18 students to sharpen 18 pencils in one minute B) y & 1/x. Then y = K/x where K is our constant of proportionality.Then K = yx. When x = -64 and y = -16 then K = -64 * -16 = 1024. Option DC) When x = 3 y = 8. So for an inverse variation K as calculated from B = 3 * 8 = 24.Then when K = 24 and y = 6; we have 24 = 6x. Hence x = 4. Option A
Answer: K= 8/3 or 2 2/3
Step-by-step explanation:
The answer is 10/3, the whole number form of it is 3 1/3 :)
Answer:
Coordinate D. Because D lies on the 2nd quadrant, meaning that x has a negative value whereas y is positive.
