Answer:
(3,2)
Step-by-step explanation:
Since both equations are equal to each others.
2x-4=-2x+8
2x+2x=8+4
4x=12
x=3
Substitute x = 3 in any given equations but I will substitute in the first equation.
y = 2(3)-4
y = 6-4
y = 2
Answer:
The answer is B
Step-by-step explanation:
2021 - 1962 =59
59-13=46
2021-46=1975
Then 7+3=10
Answer:
x = - 7
Step-by-step explanation:
Using the rule of exponents
× 
= 
Given
× 
= 6², then
= 6²
Since the bases on both sides are equal then equate the exponents
9 + x = 2 ( subtract 9 from both sides )
x = - 7
That would be
f(x) = (x - 2)(x - 3)(x + 3)
expanded this is f(x) = (x - 2)(x^2 - 9)
= x^3 - 2x^2 - 9x + 18
