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
4^4 * 4^(-9) = 4^(4-9) = 4^(-5) or 1/(4^5)
-0.65
-3/8
2/4
5/16
I hope this is right, the negatives should go first because you are taking away, then positives
It’s: -31
when you are simplify this expression you get -31
