Answer:
x = 1
Step-by-step explanation:
There are a couple of ways to solve this. One is to graph the left side of the equation, graph the right side of the equation, and look for the point where those graphs intersect. It is at x = 1. The first attached graph shows this solution.
__
Another method for solving such an equation is to subtract one side from the other and look for the value of x that makes the resulting expression zero.
(-2x +3) -(-3(-x) -2) = 0
A graphing calculator doesn't need to have this simplified. If it is simplified, it becomes ...
-5x +5 = 0
So, the graphed line is y = -5x+5. Its x-intercept is x=1, the solution of the original equation. The graph of this is shown in the second attachment.
Answer: 19200 years
Step-by-step explanation:
The fossil in the above question has aged for 3.3 half lives. Since the half life of a fossil is given as 5730 years, the age of the fossil will be given as:
= 5730 years × 3.3333333
= 19200 years
Therefore, the age of the fossil is 19200 years.

Answer:
Step-by-step explanation:
Part A:
3x^2 -2x -1 + 9x + 2x^2-3 = 5x^2 + 7x -4
Part B
5x^3 + 4x^2 -x-3 -(5x^2 +7x-4) = 5x^3 -x^2-8x+1
Part C:
They do show polynomials are closed for addition and subtraction because both resulted in another polynomial
