8n- (2n-3) =12
8n-2n= 12+3
6n=15
n= 2.5
Hope this helps :)
Answer:
B. 31.4
Step-by-step explanation:
● you use the equation to find the circumstance of a circle so 2(pi)r.
● plug in the numbers into the equation 2(3.14)(5)
● evaluate. 2(15.70) = 31.4
Answer: 
Step-by-step explanation:
For this exercise it is important to remember that:
1. The Addition property of equality states that:
If 
, then 
2. The Subtraction property of equality states the following:
If , then 
3. The Division property of equality states that:
If , then 
4. The Multiplication property of equality states the following:
If , then 
Then, having the following equation given in the exercise:
You need to solve for the variable "r" in order to find its value.
In order to solve for "r", you must apply the Addition property of equality adding 14 to both sides of the equation.
Therefore, you get the following solution:
Answer:
As the x-values go to negative infinity, the function's values go to positive infinity
Step-by-step explanation:
O As the x-values go to positive infinity, the function's values go to negative infinity. FALSE - it goes to positive infinity as we go to the right
O As the x-values go to zero, the function's values go to positive infinity FALSE- at zero the value is zero
O. As the x-values go to negative infinity, the function's values are equal to zero. FALSE - it goes to positive infinity as we go to the left
O As the x-values go to negative infinity, the function's values go to positive infinity TRUE - it goes to positive infinity as we go to the left
Sometimes true, depends on d. ex: -8 + -8 is negative, but -8 + 9 is positive
