Answer:
A cookie store sells 6 varieties of cookies. It has a large supply of each kind. How many ways are there to select 15 cookies if at most 2 can be sugar cookies?
Convert to Y=MX+B to make it easier, minus 2x from both sides to get -7y=-2x+14, then divide it all by -7 to get y=2/7x-2. 2 equals your starting point, from there go down 2 and over 7 for you slope and repeat until the graph is done.

Answer:
6-hours
D = C + T
Step-by-step explanation:
The following equations represent the total distance travelled by each vehicle, the truck (C) and the Train (T) where x is the amount of time travelling in hours...
C = 45x
T = 60x
Since the truck traveled 2 hours longer than the train we can add this value to the variable x in the truck's distance equation and then make both equations equal one another to calculate the number of hours before they cover the same distance...
45(x+2) = 60x ... distribute 45 evenly
45x + 90 = 60x ... subtract 45x from both sides
90 = 15x ... divide both sides by 15
6 = x
Finally, we can see that both vehicles would have traveled the same distance at the 6-hour mark. Now to calculate the total distance traveled (D) we can use the following equation...
D = C + T
The two angles shown form a linear pair.
The angles are supplementary, which means their measures add to 180 deg.
Now we can write an equation and solve for x.
5x + 120 = 180
5x = 60
x = 12
Answer: x = 12
