N² - 49 = 0
<u>   + 49  + 49</u>
        n² = 49
         n = <u>+</u>7

The solution to the problem is {7, -7}.

So n^{2} - 49 = 0
Add 49 from 0 and you get
n ^{2} = 49
Only 7^{2}= 49 so n = 7

Which of the following describes how to translate the graph y=|x| to obtain the graph of y=|x-6|
Lera25 [3.4K]

You transformed the function as follows:

f(x)\mapsto f(x-6)

All trasformations of the fashion f(x)\mapsto f(x+k) translate the function horizontally, k units right if k is positive, k units left if k is negative.

In your case, k=6, so you translated the original function y=|x| 6 units to the right.

PLEASE HELP ASAP!!!
Dimas [21]

Step-by-step explanation:

5x^2+2x=1

5x^2+2x-1=0

x=-b+/-√b^2-4ac÷2a

x=-2+/-√-2^2-(4×5×-1)÷2×5

x=-2+/+√4--20÷10

x=-2+/-√24÷10

x=-2+√24÷10 or -2-√24÷10

x=-2+4.9÷10 or -2-4.9÷10

x=2.9÷10 or -6.9÷10

x=0.29 or -0.69
