Question

I need help on number 8

Answer 1

Hello from MrBillDoesMath!

Answer:

y >= 8

Discussion:

The equation

y - 16 > = -8 => add + 16 to both sides

y - 16 + 16 > = -8 + 16 =>

y >= 8

NOTE: in your figure you show y > 8. That is NOT correct as it excludes the point 8 which is a valid solution. Similarly your graph shows an open circle (for not included, for x = 8). That should be a FILLED circle as x= 8 is included in the solution set. Get it? You had the solution but for some reason you incorrectly excluded x = 8.

Thank you,

MrB

Answer 2

W = 20 inch

Explanation:

To find L or W you would need to divide A/(L or W) to get ( L or W)

so right now ur looking for w so ur eqation would be

A/L = W

so 10/(1/2) so with be 20
