Christian is training for a swimming competition He starts swimming 10 ft. from the shore to his boat The table below represents the distance from the shore. f(z), as a function of time after z minutes of swimming.

f(x) = 20x + 10

Step-by-step explanation:

(0 , 10) ; (3 , 70)

Slope =

y- intercept = 10

f(x) = mx + c

     = 20x + 10

it goes up by 60 each time

Step-by-step explanation:

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)

b
