Answer:
0.38
Step-by-step explanation:
I think you meant hundredth but I'm not sure. the hundredths place is the second one behind the decimal, which is the number 8. Behind the 8 is a 2, if you use your rounding skills then you know that 5 or more you go up and 4 and lower you round down. 8 will stay the same because 2 isnt higher than 5. Once you round, every other number behind it goes away so you're left with 0.38
<span><span>x-4x+12=6
-3x+12=6
-3x+12-12=6-12
-3x=-6
-3x/-3=-6/-3
x=2
Plug (2) in for x in L2 and solve for y:
y=2(2)-6
y=4-6
y=-2
The solution (x,y)=(2,-2)
Check in both equations by substituting (x,y)=(2,-2) and see if it equals out:
L1) (2)-2(-2)=6
2+4=6
6=6 L1 checks out.
L2) (-2)=2(2)-6
-2=4-6
-2=-2 L2 checks out also, so we can say with confidence that the solution is right.

Answer:
by solving 3
Step-by-step explanation:
Answer:
4 seconds
Step-by-step explanation:
where h=height reached after t seconds
= Initial Height of the ball
The ball is dropped from a height of 205 feet,
= 205 feet
We want to determine the time it takes the ball to reach the ground.
i.e. when height of the ball, h=0
Substituting = 205 feet and h=0 into the formula
Add to both sides
Divide both sides by 16
≈ 4 Seconds
It takes approximately 4 seconds for the ball to reach the ground.
