Bryn is riding his bike at a constant speed from school to the library. His distance from the library in kilometers, x hours after leaving school can be modeled by the equation y = 20 – 12x. What do x, y, 20, and 12 represent in the equation? Be sure to specify units.

(-1,0) and (4,0) are x-intercepts.

step-by-step explanation:

x-intercepts are all points on the x-axis.

points (-1,0) and (4,0) are both x -intercepts.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
