Answer:
x is greater than or equal to -7 but less than 9.
Step-by-step explanation:
Find the lowest and higest points on the graph.
Remember the domain is on the x - axis.
The lowest point on the graph is -7, but the dot is filled in so it must be equal to it.
The next step is that the graph is getting larger so it is greater than or equal to.
On the other side of the graph do the same but it is less than not equal because the dot is open.
The top answer is 1 and the bottom answer is 2
Step-by-step explanation:
use the formula: (a+b)³ = a³+3a²b+3ab²+b³
and place the corresponding values.
Answer:
9x² - 12x + 4
Division Property
Step-by-step explanation:
(3x-2)² = (3x-2)(3x-2)
using the foil method we get:
9x² - 6x - 6x + 4
combine 'like' terms to get:
9x² - 12x + 4
2x = 10 To get 'x' by itself, since it's being multiplied by 2 we must do the inverse operation which is division
If we divide one side of an equation by 2 we must do the same to the other side, giving us:
x = 10/2 which is x = 5
