80% of 150
step 1: 80% is a percentage, so you convert that into a decimal(just move it over two places)
step 2: Multiply .80(150)= 120
3/4 of 200
step 1: 3/4 is also 75%
step 2: 75% is a percent, so you change that into .75
step 3: Multiply .75(200)= 150
So 3/4 of 200 is bigger

<h2>
![{g}^{ - 1} ( - 2) = \frac{9}{2}](https://tex.z-dn.net/?f=%7Bg%7D%5E%7B%20-%201%7D%20%28%20-%202%29%20%20%3D%20%20%5Cfrac%7B9%7D%7B2%7D%20)
</h2>
Step-by-step explanation:
To find g-¹( 2) we must first find g-¹(x)
To find g-¹(x) equate g(x) to y
That's
y = g(x)
We have
y = - 2x + 7
Now interchange the terms that's x becomes y and y becomes x
We have
x = - 2y + 7
Make y the subject in order to find g-¹(x)
Move 7 to the left side of the equation
- 2y = x - 7
Multiply both sides by - 1
We have
2y = 7 - x
Divide both sides by 2 to make y stand alone
That's
<h3>
![y = \frac{7 - x}{2}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B7%20-%20x%7D%7B2%7D%20)
</h3>
So we have
<h3>
![g ^{ - 1} (x) = \frac{7 - x}{2}](https://tex.z-dn.net/?f=g%20%5E%7B%20-%201%7D%20%28x%29%20%3D%20%20%5Cfrac%7B7%20-%20x%7D%7B2%7D%20)
</h3>
Now to find g-¹(- 2) substitute the value of x that's - 2 into the expression
We have
<h3>
![{g}^{ - 1} ( - 2) = \frac{7 - - 2}{2} \\ {g}^{ - 1} ( - 2) = \frac{7 + 2}{2}](https://tex.z-dn.net/?f=%20%7Bg%7D%5E%7B%20-%201%7D%20%28%20-%202%29%20%3D%20%20%5Cfrac%7B7%20-%20%20-%202%7D%7B2%7D%20%20%5C%5C%20%7Bg%7D%5E%7B%20-%201%7D%20%28%20-%202%29%20%20%3D%20%20%5Cfrac%7B7%20%2B%202%7D%7B2%7D%20%20)
</h3>
We have the final answer as
<h3>
![{g}^{ - 1} ( - 2) = \frac{9}{2}](https://tex.z-dn.net/?f=%7Bg%7D%5E%7B%20-%201%7D%20%28%20-%202%29%20%20%3D%20%20%5Cfrac%7B9%7D%7B2%7D%20)

Answer:
Valid
Step-by-step explanation:The term "valid" generally refers to a property of particular statements and deductive arguments. This term is used to describe an argument or proof that is logically correct. That is, its conclusion stems from its assumptions or premises.
A valid argument is one that the conclusion necessarily follows from the premises. That is, if the premises are true, the conclusion will also be true.
Suppose you are presented with two true premises. If you accept that both are true, then you will have to accept that the conclusion is also true, because there is no possibility that the conclusion is false in this case.
