y = 6x − 8
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points)
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer.
Answer:
A.
y = 3x - 5
y = 6x - 8 We simply subtract the second equation from the first. This eliminates y:
0 = 3x - 6x - 5 - (-8)
0 = -3x - 5 + 8
3x = 3
x = 1
Now substitute for x in first equation:
y = 3(1) - 5
y = -2.
B. x = 1 and y = -2 are the values that satisfy both equations. So the liones will intersect at this point (1, -2).
y = 3x - 5
y = 6x - 8 We simply subtract the second equation from the first. This eliminates y:
0 = 3x - 6x - 5 - (-8)
0 = -3x - 5 + 8
3x = 3

Answer:
Yes, n = -2.9 is a solution to the given inequality.
Step-by-step explanation:
To determine if n = -2.9 is a solution to the inequality 10.4 ≥ -2n + 4.6, substitute the value of n into the inequality.
10.4 ≥ -2(-2.9) + 4.6
10.4 ≥ 5.8 + 4.6
10.4 ≥ 10.4
Since the last line of the inequality states that 10.4 is greater than or equal to 10.4, which is true, this means that the original inequality holds true when n = -2.9.
So, n = -2.9 is a valid solution to the inequality 10.4 ≥ -2n + 4.6.

Answer:
In the picture attached the graph of h(x) = f(x)/ g(x) = (x - 6)/(x + 6) is shown. Notice that there is no h(x) for x = -6. The graph was made with a computer software
f(x) = x - 6 and g(x) = x + 6 are also included. These two functions are continuous for all real numbers, despite that h(x) is not continuous in x = -6
