Answer:
Step-by-step explanation:
You will compose the functions (that is, plug x into one function, plug that function into the inverse function, and then simplify) and verify that you end up with just "x". Here's what it looks like: Determine algebraically whether f (x) = 3x – 2 and g(x) = (x + 2)/3 are inverses of each other.
7.8 if the hundreth place is larger than 4 than the tenth place moves up a number
Answer:
none of the above
Step-by-step explanation:
A graphing calculator shows the zeros to be x=-2, and a double zero at x=3. Hence the factorization is ...
(x +2)(x -3)^2 = 0
The premise that 4 is a zero is incorrect, and none of the answer choices include (x+2) as a factor. The problem is unworkable as written here.
Answer:
a=-85/4
b=53/4
Step-by-step explanation:
17x(5+a)=17xb+221. (1)
85+17xa=17xb+221
85+(17xa)-(17xb)-221=0
17xa-17xb=-136
17x(a-b)=-136
a-b=-8
a=-8+b. (2)
Replace a=-8+b to (1):
17x5x(-8+b)=17xb+221
85x(-8+b)=17xb+221
-680+85xb=17xb+221
-680+85xb-17xb-221=0
-68xb-901=0
-68xb=901
b=-53/4
Replace b=-53/4 to (2):
a= -8+(-53/4)= -85/4
