Answer:
9 cm
Step-by-step explanation:
If the scale is 3cm:18 km, then x cm : 54km will be the distance between Riverside and Smithville. Since 18 *3 = 54 then 3cm * 3 = 9cm. On the map they are 9 cm apart.
The answer is the first option: it has the same domain as the function f(x) = - √(-x).
The domain is the set of x-values for which the function is defined.
The square root function is defined only for zero and positve values.
- x is positive when x negative.
So the domain for - √(-x) and √(-x) are the same: x less than or equal to zero.
S= Sydney
devaughn= s-13
so s+s-13=75
2s-13=75
now I think you can solve the rest.
Maybe the other person can help you but Sorry only doing this for points
