Solve the following inequality. 2 x < 8
JulsSmile [24]

Answer:

x < 4

Step-by-step explanation:

Step 1: Write inequality

2x < 8

Step 2: Divide both sides by 2

x < 4

We see here that any value of <em>x</em> less than 4 will work. So numbers like 1, 0, -124 or even -14687206589174 would work.

For which interval is the average rate of change of f(x) negative? On a coordinate plane, a function starts from above quadrant
Harlamova29_29 [7]

The interval for which the average rate of change of f(x) is negative is; from x = 0 to x = 2.5.

For the average rate of change of f(x) to be negative, it means that the change in y and the change in x must have opposite signs.

For example, if the change in y is negative, them the change in x must be positive.

Similarly, if the change in y is positive, then change in x must be negative.

Now, the graph showing this quadratic function is missing and so i have attached it.

From the graph, the only interval at which the rate of change for y and x have opposite signs is from x = 0 to x = 2.5.

In this interval, we see that x is increasing from 0 to 2.5 which is positive change while y is decreasing from 1 to -3 which is negative change.
