The sum of a number and it's reciprocal is 2 1/30 find the number
Marina86 [1]
Hopefully you are able to clearly see the steps I have taken toward solving this problem in the attachment. In case you have trouble understanding what a reciprocal is, the reciprocal of a number is simply the number flipped. So, if you are given 1/2 and asked what the reciprocal is, it would be 2/1, or just 2. That being said, if you are given a whole number, simply remember that a whole number is ALWAYS equal to itself over one. So, in this case, the "sum of a number and its reciprocal" would be n + 1/n

Consider f(x) = 1.8x – 10 and g(x) = −4.
erastova [34]

Answer:

Step-by-step explanation:

The input value at which f(x) = g(x) can be found by setting the right sides of each of those equal to each other and solving for x.

1.8x - 10 = -4 and

1.8x = 6 so

x = 3 1/3

The bold equation is the answer to the first part, and the second part is that x = 3 1/3
