Let x(t) be a harmful insect population (aphids? ) that under natural conditions is held somewhat in check by a benign predator insect population y(t) ( assume that x(t) and y(t) satisfy the predator-prey equations so that the static equilibrium populations are

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake

there is no picture in order for this question to be answered

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
