Answer:
6·(-5)
Step-by-step explanation:
-5= the change of gas per hour
6= total hours the bus has
If every hour the change of gas is -5 and theres a total of 6 hour then multiplication is involved. 6 hours would be positive not negative. This creating 6·(-5).
Answer:
m=-3/4
Step-by-step explanation:
First locate two points that are on solid intersections, (-3, 2) and (1, -1).
<u>y2</u><u>-</u><u>y1</u>
Then use x2-x1' where -1 is y2, 2 is y1, 1 is x2, and -3 is x1.
Plug in numbers, <u>-1-2</u><u> </u>= <u>-</u><u>3</u>
1+3 = 4
-3/4 is m (Slope).

Before we figure out how to rationalize a denominator, we must first understand what rationalizing a denominator does. You can rationalize a denominator when there is an irrational number (like a square root) in the denominator. To rationalize the denominator, we want to get rid of the square root/irrational number in the denominator. We can do this by multiplying by the conjugate of the denominator. The conjugate of a complex number (a number that has an irrational part) is the opposite of that number (a number that would have the opposite parity). Now, to rationalize the denominator, we multiply the fraction by the conjugate of the denominator over the conjugate of the denominator (which is equal to one). This always rationalizes the denominator.
