Tanvir graphed the relationship between the number of rotations of the screwdriver and the height of a screw head above a piece of wood. After 5
rotations the screw head height is 22 millimeters and after 13 rotations the
screw head heights is 6 millimeters. What is the rate of change?
O 2 millimeters per rotation
O 2 rotations per millimeter
1/2 rotation per millimeter
1/2 millimeter per rotation

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63

the graph is negative for all real values of x where   -6 < x < -2.

step-by-step explanation:

this refers to the values of f(x) in the area below the x-axis.
