How do you write x+y=9 in y=mx+b?

Step-by-step explanation:

all you do is move everything to one side except for y

y = 9 - x

to write in mx + b form you just switch the order

y = -x + 9

(m is -1 but you don’t need to write the 1)

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

think about it deeply and passionately about this property
