and if you were to subtract 5 - 9 it would be negative 4

A fishing hook is at an elevation of −12 m relative to sea level. Half an hour later, the fishing hook's elevation increases by

yulyashka [42]

Answer:

$-12m + 12m =0$

Step-by-step explanation:

Given

$Initial\ Position = -12m$

$Rise = 12m$

Required

Represent as an equation

The new position of the hook is calculated by:

$New\ Position = Initial\ Position + Rise$

This gives:

$New\ Position = -12m + 12m$

$New\ Position = 0$

Hence, the equation is:

$-12m + 12m =0$

50x+40=y for doors galore

40x+60=y for g&h

I can't graph here sorry but hopefully you know how that works

9. 40x+60=50x+40

-40

40x+20=50x

-40x

10x=20

x=2

10. Doors galore because 1 hours equates to 90 while g&h is 100 and so 90>100 then Doors galore is cheaper

thank you & if this helped pls don't forget to give brainiest
