Answer:
The factors of x²-64 is equal to (x-8)(x+8).
Step-by-step explanation:
The given expression is:
x²-64
we know that, 8² = 64
So,
(x²-8²) = (x-8)(x+8) [As (a-b)(a+b) = a²-b²]
So, the factors of x²-64 i equal to (x-8)(x+8).
The answer which we found by inspection is
B. f(x) = -1/2x + 3

Answer/Step-by-step explanation:
3. By substitution method, let's substitute
for y in the first equation.
Thus,
Solve for x

Add 4 to both sides




Multiply both sides by 3


Divide both sides by 5

Now, substitute 3 for x in the equation.




The solution of the equation is x = 3, y = -2
4. Solving by elimination, let's try to eliminate the x-variable by adding both equation together.


=> 
Divide both sides by -3 to solve for y


Substitute -5 for y in the first equation to find x


Subtract 10 from both sides


Divide both sides by 3


The solution is
