Answer:
248*a=391
Step-by-step explanation:
The difference between properties of equality and properties of inequality that you need to take into account when you are solving equalities and inequalities is the effect that some operations have on the sign.
1) The multiplicative property of equality permits you to multiplicate both members (sides) on an equality times a factor and the equality will remain. But in an inequality, while the factor is positive the inequality will remain but when the factor is negative, the sign of the inequality will change.
2) The same is true about the division property:
3) When you use othe functions like absoulte value and square root you will also need to be attentive of the effect of the function on the sign of the equality,.
She flipped both of the fractions instead of keeping the first one how it is
The <em>resulting</em> function is presented in the image attached below.
In this question we know the graphic of a function and we must draw a <em>new</em> function which is the reflection of the <em>original</em> one around the x-axis. Mathematically speaking, a reflection a around the x-axis is defined by the following operation:
![f'(x) = f(x) - 2\cdot [f(x) - 0]](https://tex.z-dn.net/?f=f%27%28x%29%20%3D%20f%28x%29%20-%202%5Ccdot%20%5Bf%28x%29%20-%200%5D)
(1)
Which means that the <em>reflected</em> function is equal to the <em>original</em> function multiplied by -1.
Now, we proceed to represent the <em>reflected</em> function graphically.
