If y = 3x3 – 2x and dx, dt equals 3, find dy, dt when x = –2. give only the numerical answer. for example, if dy, dt = 4, type only 4.

y=3x^3-2x, dx/dy =3

dy/dt= ? (when x=-2)

dy/dt= d/dt (3x^3 -2x)

      = 9x^2(dx/dt) -2(dx/dt)

      = 9(-2)^2 * 3 - (2*3)

      = 9(4)*3 -6

      = 102

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

u

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
