For what values (cases) of the variables the expression does not exist: b/a+b
Dmitry [639]

Answer:

The expression b/(a +b) does not exist when a = -b or b = -a

Step-by-step explanation:

The expression b/(a + b) does not exist if the denominator a + b = 0.

So, a = - b or b = -a.

So, the expression b/(a + b) does not exist when a = -b or b = -a.

When a = -b values, the denominator a + b = -b + b = 0. This will make the expression b/(a + b) = b/0 = ∞ which undefined or does not exist.

When b = -a values, the denominator a + b = a + (-a) = a - a = 0. This will make the expression b/(a + b) = -a/0 = -∞ which undefined or does not exist.

So the expression b/(a +b) does not exist when a = -b or b = -a

the angles shown here are pair of alternate interior angles .

which are equal,

so,

=》12x - 18 = 5x + 19

=》12x - 5x = 19 + 18

=》7x = 37

=》x = 37 / 7

If f(x) = 3a|2x – 4| – ax, where a is some constant, find f ′(2).
alisha [4.7K]
<span>|x| is x if x>0
|x| is -x if x<0
|x| is 0 if x=0
so
(|x|)'=1 when x>0
so
(|x|)'=-1 when x<0

</span><span> (|2x-4|)'=2 when x>2
and
(|2x-4|)'=-2 when x<2
</span>
<span>Therefore the left derivative doesn't equal the right derivative as x approaches 2.</span>
