Write the rational number as a decimal. −18/5

-3.6

Step-by-step explanation:

When plugged into a calculator, the answer turns out to be -3.6, which is a decimal.

The answer is -3.6.

Step-by-step explanation:

The first step to writing a rational number in decimal form is converting the fraction into a mixed number. -18/5 in mixed number form is -3 and 3/5. From this, you can get that the answer is going to be something that starts with a -3. Then you divide 3 by 5 and get 0.6. Put them together and you have -3.6. I hope this helps. I hope you have a wonderful day!!

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
