The lines whose equations are 2x + y = 3z and x + y = 6z intersect at which point?
1 answer:
2x + y - (x + y) = 3z - 6z -------------------------------------------------------- <span>x = -3z </span> ------------------------------------------ <span>(-3z, 9z) </span> ---------------------------------- <span>(x,y,z) = (-3z, 9z, z) </span>-------------------------- <span>x = -3z, y = 9z --------------------- There for the answer is </span><span>(-3z, 9z) </span>

Answer:
A=SqRt(c^2-b^2)
Step-by-step explanation:
a^2 + b^2 = c^2
rearrange to solve for a^2
a^2= c^2-b^2
take the square root of each side
a= square root (c^2-b^2)
Answer:
5 seconds it will hit the water.
Step-by-step explanation:
y=-16t²+400
add -16t² to both sides
-16t²=-400
divide both sides by 16
t²=-25
t=√25
t=5
