It would be positive 8 for one negative into a opposite is positive but opposite opposite is -8
Answer is 1st option
16x²-81
(4x)² - 9²
Thus it is the difference of squares of 4x and 9
Factorising (4x)² - 9² , we would get:
(4x + 9)(4x - 9)
As a² - b² = ( a + b)(a - b)
Answer:
x = -6
Step-by-step explanation:
Represent the two numbers as x and x+1.
Then their sum, x + x + 1, is 8 less than three times the difference of the two numbers. Represent the difference as x - (x+1), or -1. 8 less than three times this -1. Then:
x + x + 1 = 3(-1) - 8, or
2x + 1 = -11, or 2x = -12. Solving for x by dividing both sides by 2, we get:
x = -6.
The first number is -6 and the second is -6+1, or -5.
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
----> parent function
To obtain 
The rule of the translation is
(x,y)------> (x+4,y)
That means ---> The translation is 4 units at right
using a graphing tool
see the attached figure
therefore
The graph of f(x-4) is the translation of f(x) 4 units at right
