Answer:

x = 8

Step-by-step explanation:

These angles are alternate interior angles and m is parallel to n, so they're congruent, meaning that they're equal!

So we can make our equation:

6x - 2 = 46

6x = 48

x = 8

Hope this helps!

Let y- 2t+ 5 be a linear function representing the distance from home for an ant tminutes after starting out from a location nea

blondinia [14]

The 5 represents the starting distance from home. In other words, when t = 0, the value of y is y = 5. Replacing t with 0 leads to this y value. This is the y intercept. So at time 0 minutes, the ant is 5 units from home. Replace "units" with whatever units you happen to be using.
