Answer:
Step-by-step explanation:
We have been given that
We can use the formula for difference of cubes to simplify the function f(x)
difference of cubes - 
And g(x) can be written as
Thus, we have
On cancelling the common factors, we get
Answer:
Step-by-step explanation:
Sum of the angles of a triangle is ALWAYS 180°.
2x+3x+5x = 180°
10x = 180°
x = 18°
2x = 36°
3x = 54°
5x = 90°
The angles are 36°, 54°, and 90°
Answer:
To evaluate a function, substitute the input (the given number or expression) for the function's variable (place holder, x). Replace the x with the number or expression. Given the function f (x) = 3x - 5, find f (4). Solution: Substitute 4 into the function in place of x.
Step-by-step explanation:
1) 6x-7y=-11
2) x=-2
3) y=-4x+1
4) y-5=3(x-1)
