Examples :
(-2)^3 = (-2)(-2)(-2) = - 8
(-3)^4 = (-3)(-3)(-3)(-3) = 81
(-1)^5 = (-1)(-1)(-1)(-1)(-1) = -1
** if the exponent is an even number, the answer will be positive. if the exponent is an odd number, then the answer will be negative
** but keep in mind....if the negative is not included with the base..
-(5^2) = - 25....but (-5^2) = 25
Answer:
45x
Step-by-step explanation:
Just expand and coolect to get 9x5=45 and add x
Answer: go to the website
Step-by-step explanation:
C, because the equation of the table is y=80x. The equation for the graph is y=45x. When x is 11, you have 880 and 495. The difference is 385.
Answer:
x = 0
Step-by-step explanation:
Given
x² = - 4y ( divide both sides by - 4 )
y = - 
x²
Which is a parabola opening vertically down with it's vertex at (0, 0) and symmetrical about the y- axis
Hence equation of axis of symmetry is x = 0
