Answer: D. $24.30
Step-by-step explanation:
I'm not completely sure.
The answer is -4,7
The denominator can't equal zero. Factor the denominator:
x^2 - 3x - 28=
(X - 7)(x + 4); next set each set of parentheses equal to 0;
x - 7 = 0; so x=7 is one value
x + 4 = 0; so x=-4 is the other
Remember, x = 7 and x= -4 make the denominator zero, which is a "restriction" because you can't divide by zero.
Answer:
f(g(x)) =

Step-by-step explanation:
f(x) =

g(x) = 8x - 13
f(g(x) =

Answer: x < 3
Step-by-step explanation:
Solve the rational inequality by combining expressions and isolating the variable x.
5 people x $5 appetizers = $25
5 people x $10 main dish = $50
Total cost for the group of 5 = $75
$75 - 20% (.2) = $15 each person has to pay
