Can someone please help me, I'm stuck.
Find all numbers for which the rational expression is undefined.
7/(3v+7)
It is undefined when the denominator, 3v +7, equals zero.
That would be when v = -7/3
-8/3
To find the numbers for which the rational expression 7/(3v+7) is undefined, we need to determine when the denominator (3v+7) is equal to zero. When the denominator of a rational expression is zero, the expression becomes undefined.
So, let's set the denominator equal to zero and solve for v:
3v + 7 = 0
To solve this equation for v, we can isolate v by subtracting 7 from both sides:
3v = -7
Dividing both sides by 3, we find:
v = -7/3
Therefore, the rational expression 7/(3v+7) is undefined when v = -7/3.
