Answer:
16.80 ft long
Step-by-step explanation:
<em>Equivalent equations are systems of equations that have the same solutions. Identifying and solving equivalent equations is a valuable skill, not only in algebra class but also in everyday life. Take a look at examples of equivalent equations, how to solve them for one or more variables, and how you might use this skill outside a classroom. Putting these rules into practice, determine whether these two equations are equivalent: 1. x + 2 = 7 2. 2x + 1 = 11 To solve this, you need to find "x" for each equation. If "x" is the same for both equations, then they are equivalent.</em>
Step-by-step explanation:
x²+y²−8x−2y=48
the radius => √[(8/2)² + (2/2)² +48] =
√(16+1+48) =√65
the center => (8/2, 2/2)
=> (4, 1)
Answer:
the ball is on the ground after 3 seconds right so it would still be on the ground
Step-by-step explanation:
First you factor 128 to get two numbers (one has to be a perfect square)
You can then break them down into separate square roots like so
Then you simplify the root of 64
And finally, multiply the 2 by the 8 and you have your final answer
