Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
A cubic with a positive leading coefficient will have a general trend of upward to the right. (If the leading coefficient is negative, it will trend downward.) If there is only one real zero, it will cross the x-axis exactly once. There may or may not be two turning points, but there won't be any more than that. (There may be no turning points.)
The attached graph shows a couple of examples. The turning points and inflection points may be on either side of the x-axis.
Answer:
A coefficient is the number that the variable is multiplied by.
The variable is the unknown value, often represented by a letter or symbol.
The constant is the number that is not affected by a variable value, hence the term "constant."
Using the logic above, we can conclude that 4 is the coefficient, x is the variable, and -12 is the constant.

Answer:
I do not see all the graphs but it would be the reverse of what is shown for A. graph. The tickets sold to total income would have to be a 1:4 ratio where every 4 dollar leap in the y-axis is a one point (1 unit change in x).
Step-by-step explanation:
Answer:
x+2y=- 7
x-2y =9
Step-by-step explanation:
Solving Steps
2x+4y=-14
x-2y=9
Divide both sides
(2x+4y) ÷2=-14=2
{x-2y=9
Remove the parentheses
Divide
2x÷2+4y÷2=-7
x-2y =9
Divide
Solution
x+2y=- 7
x-2y =9
