-450 and can i get brainliest

**Answer:**

x = 4.45 or x = - 4.45

**Step-by-step explanation:**

Here are the steps:

Substitute the values,

÷ 2 × 1

x = 2 ± √6

x = 4.45 or x = - 4.45

<em>good luck, i hope this helps :)</em>

One line passes through the points (-2,3) and (0,-3) , it means the y intercept is b=-3

and slope m =

So the equation of line will be

And the inequality should be

Or

And the other line passes through (-2,3) and (0,2)

So the y intercept is b=2

and the slope is

So the equation of line will be

Or

So answer is

**Answer:**

The Answer is A.) -4

**Step-by-step explanation:**

**Answer:**

This is a proportional relationship, the constant of proportionality is 20m/s and it represents that the horse can run 20 meters every second.

Equation: d = 20s, where d=distance and s=number of seconds.

**Step-by-step explanation:**

In order to find out whether this relationship is proportional, you need to see if the rate at which the horse runs is constant (the same). If you look at the three sets of data (24, 480), (40, 800) and (60, 1200) where the pair is (seconds, meters), you can see that for any two sets of data the change in meters divided by the change in seconds is consistently 20m/s. For example:

Since the constant is 20, we know that the horse can run 20 meters every second. To find the horse's total distance, we need to multiply the rate by the number of seconds that it runs:

d = 20s
