Well, point slope is y - y1 = m(x-x1) So A and D are out. And the negative would cancel each other out for a positive, answer being, B.
Answer:
Step-by-step explanation:
Given
80.106
Required
Write in expanded form
First, we need the place value of each digit:
Next, we multiply each digit by its place value, to give the expanded form;
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.
So one trip = 4 km
two trips = 8
8 + 4 = 12
i believe your answer is 12
Thanks!
