The answer is 59. First you multiply 4 by 5 (20), then subtract 20 from 79 (59).
$18. Multiply 30 by 0.4 and subtract that value from 30 to get the price after the percentage taken away.
0.03x + 15 y = 0.03x - 15 y = -0.03x + 15 y = -0.03x - 15
Answer:
Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, a=-b
Step-by-step explanation:
The domain refers to values for which the expression is defined.
This implies that, the denominators are not equal to zero.




Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, and a=-b
