The table shows the ratio between the number of books ordered and their cost: number of books cost (dollars) 7, 28 8,32 9,36 find equivalent ratios when the number of books ordered is 1, 2, and 3. write them as ordered pairs in the form (x-coordinate, y-coordinate). starting from the origin, explain how to plot the three equivalent ratios on a coordinate grid. (20 points).

7 books costs $14, etc.  We have points in a line

(7,14)

(8,16)

(9,18)

They're all points on the line y=2x which just means it costs $2 a book.  So 1 book costs $2, 2 cost $4, and 3 cost $6.  We have three new points:

(1,2)

(2,4)

(3,6)

On the same line, y=2x, just closer to the origin than the first three. We plot a point at x=1, y=2,

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)

wow ok so the answer is 1k or just k

because of combining like terms xd
