Solve simultaneously:
<span>15x-8y=52 and
6x+14y=38
</span>
Let's solve this system thru elimination by addition/subtraction:
Let's get rid of the x terms.
To do this, mult. the first eqn. by -6 and the second by 15. (This is not the only way in which we can do this!!) We get
-90x + 48y = -312
90x +210y = 570
--------------------------
Add all 3 columns together. We end up with:
258y = 258, so y = 1. You can find x by subst. 1 for y in either of the given equations.

The expression:
gives the distance traveled by the aircraft in t hours, so, for t = 6:
Answer:
Step-by-step explanation:
The given function is
To find F(2), we substitute t=2 into the function.
This means that wherever we see t, we put 2
We multiply the exponent in the denominator to get:
We evaluate to get:
We now cancel the common factors to get:
