Step-by-step explanation:
12a-9a>-12+6
3a>-6/:3
a>-2
What you want to do, is isolate the y by itself to rewrite the equation as y=mx+b. So when you move the 5x over the equation looks like this -6y=-5x+30. Then you divide the -5x+30 by -6 to isolate the y. Thus making the equation y=5/6x-5. And since there is only one answer with the y-intercept as (0,-5); The answer is A.
So the surface area of a box has this equation: A = 2 (wl + hl + hw)
w = width = 38
l = length = 38
h = height = 0.25
Plugging in:
A = 2 ((38*38) + (38*0.25) + (38*0.25))
= 2926 square meters
Answer:
X=-1
Y=-9
