I used the person can see 49km which is my V
SO 49 = 3.5 sqrt (h)
or 49/3.5 = sqrt(h)
or sqrt(h) = 14
or h= 196
So the height is 196

Answer: y = 2
Step-by-step explanation:
we need to use systems of equations, basically since we know what x equals, we plug that into first equation so:
since x=2y+1,
we can say that:
(2y+1)+2y=9
then we solve this equation,
first we expand the brackets- 2y+1+2y=9,
then we combine like terms- 4y+1=9
then we take 1 away from both sides- 4y=8
then we divided both sides by 4
y=2
Hope this helps xx
