s(4) This means that t = 4, so you can plug in 4 for "t" in the equation
s(t) = 9t - 4
s(4) = 9(4) - 4
s(4) = 36 - 4
s(4) = 32
(4 , 32) This is the point on the graph. To graph it, each unit/square can be 4 [so go by 4's]
7/12 < 2/3 < 3/4 is the correct answer
<span>4 lb is BIGGER. There are 16 ozs in a pound, so 40 oz = 2.5 lb, which is less than 40 pounds</span>
Standard form : Ax + By = C
12y = 9x - 30
-9x + 12y = -30 ....some teachers accept this, with A being negative
but if not, then it is this :
9x - 12y = 30
