Answer:
379.72 meters
Step-by-step explanation:
At first, the balloon was 300 m away at 25°, so its height can be determined as:
After 5 minutes, the balloon was at 60°, so its height can be determined as:
To find the distance traveled by the balloon during that period, simply subtract the second height by the first one:
The balloon traveled 379.72 meters in that time.
One way is subsitute
I like solving
so
what you do is this
add the equaitons to gether to eliminate x
2y=x+5
<u>3y=-x-3 +</u>
5y=0x+2
5y=2
y=2/5
sub back
2y=x+5
2(2/5)=x+5
4/5=x+5
minus 5
4/5-25/5=x
-21/5=x
the point is (x,y) or
(-21/5,2/5)
aprox
(-4.2,0.4)
I think they wanted you to read the garph you should have attached and guess the answer
the closes one is
hmm, x=-3
and y=1
so then D is the answer
we have
we know that
so
two solutions
<u>first solution </u>
the first solution is the interval---------> (-1,∞)
<u>second solution</u>
the second solution is the interval---------> (-∞,-1)
therefore
the solution is all real numbers except the number 
the answer in the attached figure
I think it's 8 miles in one month if you round it I don't know what the exact decimal would be.
Sophia = (6/6 + 5/6) 5 = 9.16666…
9.1666… is equal to 9 laps
