Answer:
X=9 or x=-9
Step-by-step explanation:
X^2=81
Can be written as
x^2-81=0
Factorize by the property:
a^2-b^2=(a-b)(a+b)
So the expression becomes:
(x-9)(x+9)=0
Therefore, either x-9=0or x+9=0
Then the solutions are x=9 or x=-9
Subtracting a number from x shifts the graph that may places tot he right
Subtracting a number at the end of the equation, shifts the graph that many units down.
The answer would be: Shift the graph of y = x^2 right 2 units and then down 10 units.
C
Trinomial means three parts
A and C or trinomial's but the degree on a is at three and the degree of C is a one
Answer:
76.75
Step-by-step explanation:
83.5 + 70= 153.5
153.5 / 2 = 76.75
Your grade would be 76.75.

6x - 4y = 8...solve for x
6x = 4y + 8
x = (4/6)y + 8/6
x = 2/3y + 4/3 <==
