Answer:

A and D

Find the unit rate of the data in the table:

y = kx

2 = 6k

k = 2/6

k = 1/3

The equation is:

y = 1/3x

Compare this with the others:

A. 3/11 < 1/3 = 3/9 ⇒ yes

B. 2/5 > 1/3 = 2/6 ⇒ no

C. 9/23 > 1/3 = 9/27 ⇒ no

D. 4/13 < 1/3 = 4/12 ⇒ yes

E. 3/8 > 1/3 = 3/9 ⇒ no

What can be concluded about the graphed polygon? mc013-1.jpg The polygon is a rectangle. Adjacent sides of the polygon are perpe

Usimov [2.4K]

From the given graph, the image is a trapezoid.
Therefore,
The first option, "the polygon is a rectangle" is incorrect.
The second option "Adjacent sides of the polygon are perpendicular." cannot be true as well because trapezoid has one the adjacent sides which is not perpendicular.
Third option" Opposite sides of the polygon are parallel", this can't be true as well because only two sides are parallel.
Fourth option " The slope of side c is 0.", this is true because line c is a horizontal line with zero rise and maximum run. Therefore,
Slope = 0 ÷ 9
 = 0
