Answer:

Step-by-step explanation:
One is given the following function (
). The given problem asks one to find the output of the function when the input is (10). Keep in mind, a general rule for dealing with functions is that, when present, the variable (x) represents the input. Whereas the variable (y) represents the output. Thus, if one were to substitute (10) in place of (x), and simplify: the result one would get is the output. Apply this idea to the given scenario:




Answer: 1.4259
Explanation: Square 2 1/2 comes up with 6 1/4 then square root that then multiply by 1/3
Step-by-step explanation:
x=k/y------(1)
k=xy
k= 7×3
k=21
from equation 1
x=k/y
y=k/x
y=21/9
y = 2.33
Answer:
y=1/2x-2
Step-by-step explanation:
the line is at its y-intercept at (0,-2) letting you know that there will be a -2 after the X.
the line is going up 1 vertical box every 2 horizontal boxes letting you know that the slope is 1/2x
