Answer:
No.
Step-by-step explanation:
To determine if (0,0) is a solution to the inequality, substitute 0 for x and 0 for y and check to see. Thus:
Substitute 0 for x and 0 for y:
Multiply:
Subtract:
So, (0,0) is <em>not</em> a solution.
And we're done!
1.x^2 +6x - 4 = 6x
X^2 + 6x -4 - 6x = 0
X^2 - 4 = 0
By difference of two squares :
X^2 - 4 = 0 can be written as (x-2) (x+2) = 0
(X-2)=0 therefore x= 2
(X+2)=0 therefore x= -2
2. X^2 - 8x = -6x
X^2 -8x + 6x = 0
X^2 - 2x = 0
X(X-2) = 0
X= 0, X= 2
To solve, simply simplify each fraction
(16/32)/(16/16) = 1/2
(12/24)/(12/12) = 1/2
True, the equation given to us is true.
