4/r+8/f=5/g solve for f

Let's solve for f.

4

r

+

8

f

=

5

g

Step 1: Multiply both sides by fr.

4f+8r=

5fr

g

Step 2: Multiply both sides by g.

4fg+8gr=5fr

Step 3: Add -5fr to both sides.

4fg+8gr+−5fr=5fr+−5fr

4fg−5fr+8gr=0

Step 4: Add -8gr to both sides.

4fg−5fr+8gr+−8gr=0+−8gr

4fg−5fr=−8gr

Step 5: Factor out variable f.

f(4g−5r)=−8gr

Step 6: Divide both sides by 4g-5r.

f(4g−5r)

4g−5r

=

−8gr

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
