Answer:
The first two graphs are the exact same but it is the first two.
Step-by-step explanation:
Answer:
(3a-1)(3a+1)
Step-by-step explanation:
This is the difference of two squares so we can factorise using the rules
x^2-y^2 = (x-y)(x+y)
In this case x = 3a and y = 1 since (3a)^2 = 9a^2 and 1^2 = 1
Answer:
the mean is 8
Step-by-step explanation:
5 +7+8+8+9+11= 48
48/6= 8
1. -8x = 3x
-11x = 0
x= 0
y= 3(0)= 0
(0, 0)
2. -7x = -4x - 12
-3x = -12
x = 4
y = -7(4)= -28
(4, -28)
Substitute the values of v & w in the equation
