Answer:
4Na + 1O2 > 2Na2O
SF6 > 1S + 3F2
2FE2O3 > 4FE + 3O2
Step-by-step explanation:
1. Identify the Products and Reactants(always do O2 last)
2. determine how many atoms of each element are present on each side of the equation
3. Add Coefficients and never change the subscripts. If there's a coefficient in front of any compound, it is distributed to both elements.
4. find the total number of atoms on both sides of the equation and make sure they equal with each other
I'm doing the same thing right now and I'm lost.

Answer:</h3>
- A. (x, y) = (1, -1)
- B. (1, -1), (2, 0)
- C. (0, 3). This is where their graphs cross, meaning g(x) = f(x) at that point.
<h3>
Step-by-step explanation:</h3>
A solution to a pair of equations is the set of points where their graphs intersect. Points in that set will satisfy both equations, which is what "solution" means.
Here, the graphs of p(x) and f(x) each intersect the graph of g(x) in one place. Hence f(x) = g(x) has one solution, as does p(x) = g(x).
Finding the solution is a matter of reading the coordinates of the point of intersection from the graph.
A. The graphs interesect at x=1, y=-1.
B. Any point on the red line is a solution. We already know one of them from part A. Another is the x-intercept, where y=0. That point is (2, 0).
C. g(x) intersects f(x) at their mutual y-intercept: y = 3. x = 0 at that point.
(2/3)*((2/3)*m-(2/3)) = 0
(2/3)*((2/3)*m-2/3) = 0
2/3*(2/3*m-2/3) = 0
2/3*m-2/3 = 0 // + 2/3
2/3*m = 2/3 // : 2/3
m = 2/3/2/3
m = 1
