The relation between the cost of a certain gem and its weight is linear. in looking at two gems, we find that one of the gems weighs 0.3 carat and costs $3,457, while the other gem weighs 0.5 carat and costs $4,373. find a linear function that relates the price of a gem, c(x), to its weight, x, treating weight as the independent variable.

i appreciate anyone who can me. i will be reporting any foolish answers.

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)
