Answer:

gm =14sqrt(2)

or approximately 19.8

Step-by-step explanation:

to find the geometric mean, multiply the numbers together and then take the square root

gm = sqrt(28*14)

gm = sqrt(392)

gm = sqrt(196*2)

gm =14sqrt(2)

gm = 19.799

Solve 9x-y = 45 for y

zimovet [89]

9x-y = 45

Move 9x to the other side. Sign changes from +9x to -9x.

9x-9x-y=45-9x

-y=45-9x

Multiply both sides by -1

(-1)(-y)=y

(-1)(45)=-45

(-1)(-9x)

y=-45+9x or y=9x-45

Answer: y=-45+9x or y=9x-45
