9x would be the answer.

Since both 3x and 6x have the variable x in it, we can just go ahead and add 3 and 6.

3x+6x=9x

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.

A function is represented by the graph.

Morgarella [4.7K]

Answer:

see the explanation

Step-by-step explanation:

we know that

The y-intercept is the value of the function y when the value of x is equal to zero

Part 1) we have

$y=5x-6$

For x=0

substitute in the linear equation and solve for y

$y=5(0)-6$

$y=-6$

therefore

The y-intercept is the point (0,-6)

Part 2) Find the y-intercept of the function represented in the graph

Looking at the graph

For x=0

Find the value of y in the graph

The value of y is equal to y=1

therefore

The y-intercept is the point (0,1)
