Answer:
6 feet 8 inches
Step-by-step explanation:
The mirror ensures that the line of sight makes similar triangles, so ...
x/10 = 4/6
x = 40/6 . . . . feet = 6 2/3 ft = 6 ft 8 in
The mirror is 6 feet 8 inches from the goal.
Initial value is f(0) = ???
So when x = 0, y = 3
Add 10 to first equation and 7 to 2nd
5x-3y=10
x+y=7
multiply 2nd equation by 3 and add to first
5x-3y=10
<u>3x+3y=21 +</u>
8x+0y=31
8x=31
divide by 8
x=31/8
(x,y)
we can see that there is 1 answer with (31/8, somethng)
answer is A
