Tim wants to ride his bike for 25 miles or less on some mountains bike trails . The table shows the distance of three different

Basile [38]

yo sup??

the sum of trails taken should be less than 25 miles

Black bear=B

Eagle Ridge=E

Doe Run=D

(btw names sound cool XD)

we will now try different combinations

B+E=7 1/2 ++ 10 1/4 which is clearly less than 25

B+D=7 1/2 + 8 3/4 which also less than 25

E+D=10 1/4 + 8 3/4 which is also less than 25

B+D+E=7 1/2 + 10 1/4 + 8 3/4 which is greater than 25

Therefore only the 1st,2nd and 3rd case are possible

Hope this helps.

Answer:

see attached

Step-by-step explanation:

Find the y-values corresponding to x-values of 0 and 1, then plot those points and draw a line through them.

For x=0, ...

y = -4·0 -1 = -1 . . . . the point is (0, -1) . . . the y-intercept

For x=1, ...

y = -4·1 -1 = -5 . . . . the point is (1, -5)

The attached graph shows these points and the line through them.
