When she first purchased it, soledad's computer had 400 gb of hard drive space. after six months, there were only 313 gb available. write and solve an equation to find the amount of hard drive space that soledad used in the first six months.

Soledad used 87 GB in the first six month.

Step-by-step explanation:

Since we have given that

Amount of space in hard drive of computer = 400 GB

After 6 months,

Amount of space in hard drive of computer = 313 GB

Let the amount of hard drive space she used in first six months be 'x'.

According to question, it becomes,

Hence, Soledad used 87 GB in the first six month.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
