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
3 5/7 x 2 6/7
= 3.71428564 x 2.8571428
= 10.6 ft^2 (3 sig. fig.)
I think it's -2 to -1 is the right answer maybe
but i hope it helps u !!
<span>if a = 2x and b = 1
(2x)</span>³+1³ = (2x+1)(4x²-2x+1)
I hope this helps
1. iThis is shaped like a V with its vertex at the point (0,5)
( its ( 1,7)
2. -3 <= -1-1 = =2
so its (-1, -3)
