Answer:

i = 2

Step-by-step explanation:

First move -2i to the other side of the equation like this: 4 = 2i

Then divide both sides by 2: 4/2 = 2i/2

Then you get your answer!: i = 2

Answer:

5

Step-by-step explanation:

what's a math equation that equals 19? it has to be an equation with x and the answer Is 19 so whats the equation guys??
expeople1 [14]
There are many different types of equations we can use to allow x to equal 19! Below are some examples :) See if you can come up with some on your own based off of these examples:

5x = 95.....................................Divide both sides b 5

x = 19.......................................There's one for you :)

_____________________________________________________________

1 + x - 5 = 15............................Combine like terms

x - 4 = 15..................................Add 4 to both sides

x = 19
_____________________________________________________________

There's just a couple of examples, but see if you can come up with some on your own and let me know if you get stuck!

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you any further! :D

Karolina [17]

Answer:

  [0, 7]

Step-by-step explanation:

We want the height to be greater than or equal to 32 ft, so ...

  704 +16t -16t^2 ≥ 32

  t^2 -t -42 ≤ 0 . . . . . . . . . . . subtract 32, divide by -16

  (t -7)(t +6) ≤ 0

This inequality will be true for values of t between -6 and +7. Since we're only concerned with times t ≥ 0, the appropriate solution interval is ...

  0 ≤ t ≤ 7 . . . . [0, 7] in interval notation
