Answer:
- asymptotes: x = -4, x = 4
- zeros: x = 0
Step-by-step explanation:
The vertical asymptotes of the rational expression are the places where the denominator is zero:
x^2 -16 = 0
(x -4)(x +4) = 0 . . . . . true for x=4, x=-4
x = 4, x = -4 are the equations of the vertical asymptotes
__
The zeros of a rational expression are the places where the numerator is zero:
4x = 0
x = 0 . . . . . . divide by 4
Answer: The answer is 50
Step-by-step explanation:
I did the test
Answer:
(x, y)=(4,-8)
Step-by-step explanation:
9x+y=28
3x+3y=-12 /:(-3)
9x+y=28.......(1)
-x-y=4......(2)
9x+y=28
(1)+(2): 8x=32
9x+y=28
x=32/8
9x+y=28
x=4
9*4+y=28
x=4
36+y=28
x=4
y=28-36
x=4
y=-8
x=4
(x, y) =(4,-8)
Wat is help sheet, didn't help,
instructions unclear, got my calculator stuck in the ceiling fan
remember some simple exponential laws
and
first one
2nd one
third one
dunno wat to do with 'help sheet'
