Answer:
Fox is faster by 7 MPH
Step-by-step explanation:
1. determine how fast each animal runs per hour
rabbit = 35 MPH
fox = 21 per half hour (multiply by 2 for hour) 21*2=42 MPH
2. Subtract rabbits speed (35) from foxs speed (42)
42-35= 7 mph
Answer:
y- intercept =
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
f(x) = - x + ← is in slope- intercept form
with y- intercept c =
Answer:
C
Step-by-step explanation:
When completing the square, we essentially want to create a perfect square trinomial by adding a constant.
If we have the following expression:
And we want to complete the square, we will need to divide the b-coefficient by half and then square it.
Thus, the added term should be:
In the given equation, we have:
The b term here is 8. Therefore:
The value we would add would be 16.
The answer is C.
Further notes:
To complete the square, add 16 like mentioned earlier. However, we also need to subtract 16 to balance things out:
The expression inside the parentheses is now a perfect square trinomial. Factor it:
And we are done!
You can start by rewriting the equation so that the right side equals zero. Add
and
to both sides.
You can now use the quadratic equation (below), where
and
, to find solutions. Plug in these values for
and
into the equation and simplify.
The final answer is the combination of both solutions.
Or approximately...
