Answer:
- The first thing we do is find out what f(x-3) is
this is can be simplified using the rules of exponents
- Then we put that into g(x)
- The first transformation is at f(x), where it is divided by 8, and then inserted into g(x) which increases the new transformed f(x) by 4
Answer:
-7
Step-by-step explanation:
Lets assume the number Peggy is thinking of be "x".
Now as given, when twice the number is added to three times one more than the number. We can write it as
∴ --- Equation 1
Again, it is given that Peggy gets the same result as when she multiplies four times one less than the number.
∴ -- equation 2
Next, we can equate both the equation 1 and 2 as it is given that result is same.
Let´s distribute 3 into and 4 into
⇒
⇒
Subtract both side by 4x and 3
∴
∴ Peggy was thinking of -7
