Your race car can travel 1/4 mile in 3.12 seconds. what is the average speed of you race car in miles per hour. In order to calculate the speed of the car we first have to identify the suited formula for distance in this scenario.
<span>
Hence, d = 0.25 mi T = 3.12 seconds
Solution:
velocity = distance / time
</span><span>velocity = 0.25</span><span> mi / 3.12 s
velocity = 0.08 mi/s

To solve this polynomial equation, we will need to factor the left side.
On the left, we have a a trinomial in a special form that
can be factored as the product of two binomials.
The trinomial on the left can be factored which makes life easier.
This factors as (x + 11)(x - 2) = 0.
This means that either x + 11 = 0 or x - 2 = 0.
Solving each equation from here, we get x = -11 or x = 2.
So the solution is {-11, 2}.
Answer:
-12
Step-by-step explanation:
Answer:
is the correct representation of the graph.
Step-by-step explanation:
Firstly, if we look at the y-intercept, we can see that it is 25.
This means that we have narrowed down the options to the first and the second.
Next, our graph has a solid line. This means that we must have a sign.
This means that the inequality is the correct representation of the graph.
