ycow [4]

Answer:

The Final Answer would be 14.9987.

Step-by-step explanation:

Given:

$15-1.3\times 10^-3$

We need to Subtract the above number.

Since the larger number is standard Notation form and smaller number is in Scientific notation form

So first we will convert the Scientific notation Number in standard Notation form we get;

$1.3\times 10^-3 = 0.0013$

Now Subtracting the smaller Number from larger number we get;

$15-0.0013 = 14.9987$

Hence The Final Answer would be 14.9987.

Answer: 2, 4, 6, 8

Step-by-step explanation:

Just plug x into the equation for each one.

x = -3

$y=\frac{2(-3)}{3} +4\\y=\frac{-6}{3} +4\\y=2$

With this one, you can see it is a linear equation and for every increase of 3 on x, y in increased by 2.

x -6 -3 0 3 6
