Complete the square to make the binomial x^2-8x a perfect trinomial

1 answer:

3 0

The general Formula looks like this:
$x^2 +bx + ( \frac{b}{2})^2$
This really only involves 2 steps:
1) Take half of "x" coefficient. ----> -8/2 = -4
2) Square that number. ----------> (-4)^2 = 16

Perfect trinomial for this example is then:
$x^2 -8x+16$

Which graph shows that Cindy reads about 3/4 of the time while riding in the car?

wolverine [178]

The graph that shows a unit rate of 3/4, which is the time Cindy reads while riding in the car is the graph attached below.

Unit rate can be described as a constant or exactly how much of one quantity is per 1 unit of another quantity.

Unite rate (k) = x/y.

In the graph attached below, when x (hours driving) = 3, y (hours reading) = 4.

Therefore, unit rate = 3/4. We can then conclude that the graph that shows that Cindy reads 3/4 of the time she rides in a car is the graph attached below.
