Answer:
Step-by-step explanation:
-3b - 2b + 7 = -15
-5b = -22
b = 22/5
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:
x=5
Explanation:
Begin to isolate x by adding 12 on both sides of the equation
5x=2x+15
Subtract
2x on both sides of the equation
3x=15
Isolate x by dividing both sides of the equation by
3x=5
Answer:
3.2÷0.32×(0.73+0.27)^2= 10
3.5 , 7 , 10.5 , 14 , 17.5 , 21 , 24.5 . Because it increases by 3.5 each time
