Answer:
75
Step-by-step explanation:
for every 5 boys there are 4 girls
60 / 4 = 15
15 * 5 = 75
Finding limits by direct substitution means simply means to evaluate the function at the desired value: in the first case, we have to evaluate
at
: we have

Similarly, in the second example, we have

Going on, we have

And thus we have

Finally, we have

So, we can't evaluate this function at 0.
Corrected Question
Determine the values of a, b and c that make each equation true.

Answer:
a=-5, b=28 and c=-11
Step-by-step explanation:
To solve for a,b and c, we apply the following laws of indices

Therefore

To solve for b

To solve for c
