Answer:
- 4
- A. 0
Step-by-step explanation:
1. Input 3 for x and do the arithmetic.
z(x) = x+1
z(3) = 3+1 = 4 . . . . . the output is 4
__
2. The expression for n(x) has x in the denominator. The expression will be undefined when the denominator is zero, so x=0 cannot be used.
The answer is shown below:
Rectangle JKLM has an area of 36 square centimeters. The side is at least 4 centimeters long. Prove: KL is 9 centimeters. Assume that a. "KL > 0". Then the area of rectangle JKLM is greater than b.) "40 centimeters² ", which contradicts the given information that c. the area is 40 centimeters². So the assumption must be false. Therefore, d.) "KL <= 10".
Answer:
Step-by-step explanation:
In order to solve this, we are trying to find the value of 
. Basically, is a placeholder for a number that is unknown. Some number minus 3 is equal to 21.
Our goal is to find . To do this we want to isolate on one side of the equation
Let's add 3 to both sides.
Hope this helped!
