34 pts are the graphs of the lines in the pair parallel? explain. y = 4x + 6 –15x + 3y = –45 a) no, since the y-intercepts are different. b) yes, since the slopes are the same and the y-intercepts are different. c) yes, since the slopes are the same and the y-intercepts are the same. d) no, since the slopes are different.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
