Answer:
f(-3) = 9
Step-by-step explanation:
Lets define f(a) first where a is any integer,
f(a) is found out by putting the integer in the function in place of the variable
So for the given question
In order to find f(-3) we will put -3 in place of x
So putting -3,
So, the value of function at -3 is 9 ..
No solution for the quadratic equation because of the √-20
Answer:
$ 154
Step-by-step explanation
Let the value of suitcase=x
x × 4.5% = 6.93 (converted the question into equation)
x × = 6.93 (converted the percentage into fraction)
x = 6.93 x (took reciprocal of 4.5/100 after moving it to the other side of the equation)
x = (multiplied the values)
x = 154 $ (simplified the fraction)
make it the brainliest and get 20 years of luck : )
