Answer:

x=8 and is not extraneous

Step-by-step explanation:

2(x-5)+11=17

2x-10+11=17

2x+1=17

2x=17-1

2x=16

x=8

extraneous means it is a solution, but it is not possible in the equation, to determine if it is extraneous, plug it in to the original equation

2(8-5)+11=17

2(3)+11=17

6+11=17

17=17

since it works in the orignial equation it is not extraneous

nikklg [1K]

To shift vertically the graph of the function f(x), you have to add a constant to its expression:

f(x) \to f(x)+k

If k is positive, you shift the function k units above, if k in negative, you shift the function k units below.

So, if you want to shift the graph of f(x)=45x+20 two units down, you have to subtract 2 (i.e., add -2):

f(x) = 45x+20 \to 45x+20-2 = 45x+18
