Answer:
$9.90 per hour
Step-by-step explanation:
This month:
Initial pay: $10 per hour
% raise : 10%
Dollar amount of raise = 10% x $10
= 10/100 x 10 = $1
Gina's pay after the raise = $10 + $1 = $11 per hour
Next Month:
Starting pay: $11 per hour
% decrease : 10%
Dollar amount of decrease = 10% x $11
= 10/100 x 11 = $1.10
Gina's pay after decrease = $11 - 1.10 = $9.90 per hour
Answer: All the real values except x ≠ 7 and the x for which f(x)≠-3
Step-by-step explanation:
Since, For function f , the domain is R - {7}
That is, If x is any element of the domain of the function f,
Then, x ≠ 7
(gof)(x) = g(f(x))
Since, For the function g, the domain is R - {-3}
Thus, If f(x) is any element of the domain of the function g,
Then f(x)≠ -3
Hence, Fourth Option is correct.
Answer:
x is 35
Step-by-step explanation:
First do 180 -40 and get 140. Then add 3x plus x to get 4x because they are the same value/ Do 140/ 4x and get 35. X equals 35.
