Nana76 [90]

Answer:

0.0000007

And if we count the number of zeros before the number 7, we can rewrite the number like this:

7x10^{-7}

We cansolve this problem also counting the number of positions that we need to move the decimal point to the right in order to obtain the first number (7)

And the best option would be:

B. 7 x 10-7

Step-by-step explanation:

For this case we have the following number given:

0.0000007

And if we count the number of zeros before the number 7, we can rewrite the number like this:

7x10^{-7}

We cansolve this problem also counting the number of positions that we need to move the decimal point to the right in order to obtain the first number (7)

And the best option would be:

To find the slope and the -intercept of the line, first write the function as an equation, by substituting for

y=10
y=0x+10
y=0x+10 , m=0
y=0x+10 , m=0 , b=10

m=0 , b=10

The slope of the line is m=0 and the y-intercept is b=10
