Answer:

Step-by-step explanation:

h=16t^2+98=?

subtract 98 from both sides to get

h-98=16t^2

(the 98 on the right cancels)

now divide by 16 on both sides

h-98/16=t^2

(the 16 on the right cancels)

lastly take the square root on both sides

square root(h-98/16)= t

if you know what h is fill it in and it will give you your answer

Answer:

y = - 49

Step-by-step explanation:

Given

7x - 2y = 35 ← substitute x = - 9 into the equation

7(- 9) - 2y = 35, that is

- 63 - 2y = 35 ( add 63 to both sides )

- 2y = 98 ( divide both sides by - 2 )

y = - 49
