Well the first equation has a variable in it while the other one doesn't also the first expression if set equal to 0 is -2 while the other one is 5
Answer:
Your answer would be D, the last one
Answer:
x = 8 and y = 5
Step-by-step explanation:
2x - 3y = 1 --(1)
x + 2y = 18
x = 18 - 2y --(2)
sub (2) into (1):
2(18 - 2y) - 3y = 1
36 - 4y - 3y = 1
-7y = 1 -36
7y = 35
y = 5
x = 18 - 2(5) = 8
Considering it's critical points, it is found that the least possible degree of the polynomial graphed above is of 4.
<h3>What are the critical points of a function?</h3>
The critical points of a function are the values of x for which:

In a graph, they are the turning points, and if a function has n critical points, the least possible degree is of n + 1.
In this problem, the function has 3 turning points, at x = -3, between x = -3 and x = 3, and at x = 3, hence the least possible degree of the polynomial graphed above is of 4.
