Answer:
zero: x = 0
discontinuities: x = -5, x = 5
Step-by-step explanation:
The zeros of the rational function will be found where the numerator is zero. That will happen when x=0.
__
There will be discontinuities where the denominator is zero. The denominator is the difference of squares, so factors as ...
x^2 -25 = (x -5)(x +5)
These factors will be zero when x=5 and x=-5.
Answer:
1. Is (A) Subtract 2 to both sides
2. Is (C)
Step-by-step explanation:
Answer:
a = 15
Step-by-step explanation:
Plug in b = 3 into 5a-10b=45
5a-10(3) =45
5a - 30 = 45
5a = 75
a = 15
Answer:
A) 130
Step-by-step explanation:
(2x + 18) + y = 180 <--- Is True
(4x - 14) + y = 180 <--- Is True
(2x + 18) + y = y + (4x - 14)
(2x + 18) = (4x - 14)
2x + 18 = 4x - 14
-2x + 18 = -14
- 18 - 18
-2x = -32
x = 16
2(16) + 18 = 50
4(16) - 14 = 50
180 - 50 = 130
