Substitute the variable for value we're given.
-9(2) - 7
-18 - 7 = -25
So, -25 is the answer.
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:
49
Step-by-step explanation:
z=7 which means that 7 raised to the second power is 7 multiplied by itself. When you do 7 x 7 your answer will be 49. Hope that helps :)
