8.71 xx10^(12)
The exponent is a positive number. This means the decimal point moves to the right by the number of the exponent.
There are two digits to the right of the decimal point, so to move the decimal 12 places, you would need to add 10 zeros.
8.71 x 10^12 becomes 8,710,000,000,000.
Answer: A or 1.
Hope it helps :D
5+y+z I think x Something like that.
The slope-intercept form:

m - slope
b - y-intercept
<em>subtract x from both sides</em>
<em>change the signs</em>

It's a linear function.
We need only two points to plotting a graph.
We choose any three values of x and calculate y.

Pick two points
(2, 18) and (4,21)
(21-18)/(4-2) = 3/2
The slope is 3/2
