Which table shows ordered pairs that satisfy the function y=x2+1
weeeeeb [17]
I think you meant  y = x^2 + 1.  Please use " ^ " to denote exponentiation.

Since you haven't shared the table, I'll choose a few x values and find the corresponding y-values:

x   y

What is the reciprocal of 1.8?
katovenus [111]

Answer:

10/18

Step-by-step explanation:

To convert 1.8 to a reciprocal, you first need to change it into a fraction.

1.8 basically expresses 1 \frac{8}{10} which equals \frac{18}{10}.

Since a reciprocal is just switching the top and bottom of a fraction, your reciprocal of 1.8 will be \frac{10}{18}.

You can simplify this if you want, to get \frac{5}{9}. Either one is correct.
