This table shows the input and output values for a linear function
Keith_Richards [23]

Answer:

-25

Step-by-step explanation:

The "x" values in the table are INPUT

and

The "y" values in the table are OUTPUT

We see that each of the values in INPUT (x) are 1 values apart, so we can look at the difference (later - previous) for any 2 x values:

-5 - 20 = -25

-30 -(-5) = -30 + 5 = -25

and so on..

Hence, the difference is "-25"

2nd answer choice is right.

I need help =_= ty if u do
marishachu [46]

First number has to be 2.

Second number is between 7 and 9 so has to be 8

The tens and ones place needs to sum to 6, so the tens has to be less than 6 and can't be 0, 4 or 6, so has to be 2.

The ones would then need to be 6 - 2 = 4

The number would be 2,824
