Answer:
(12, -3)
Step-by-step explanation:
You can solve it algebraically or graphically. Graphically you find the intersection point. Algebraically with substitution/elimination.
We can use the distributive property to set up an expression that is equal to this problem.
14 times 8 is 112
14 times -6 is -84x
14 times 12 is 168
(If you don't know the distributive property ask and I can explain it)
We can combine that together to get:
112 +168 -84x
Or, condense it further:
280-84x is equivalent to 14(8-6x+12)
Time = distance/speed, so
3.54x10^7 / 3x10^8 = 1.18x10^-1
or, 0.118 seconds
The answer is 54 degrees I took the exam I got it right
