Divide the distance by the speed:
10^8 / 10^5 = 10^3 days ( 1,000 days)
Answer:
-3, -1, 1
Step-by-step explanation:
The values of x when f(x) = 0 are the points on the graph when the curve intercepts the x-axis.
From inspection of the graph, the curve intercepts the x-axis at
x = -3, x = -1 and x = 1
Answer:
, or in this case, 
Step-by-step explanation:
Assuming that Justine's score is represented by
and Meagan's score is represented by
, we know that
will always be the opposite of
.
To represent opposite, we put a negative sign before the variable.
This makes the current number, even if it's negative, the opposite value.
Let's test it out.
Since Justine's score is -7, substituting it into the equation makes it
. We know that two negatives make a positive, so
.
Now let's assume Justine's score is 7. Plugging it into the equation, we get
. That's the same thing as
, and -1 times 7 is -7.
Hope this helped!
