Answer:
y= 
= 0.75
Step-by-step explanation:
To subtract the second equation from the first equation, you have to divide the equation as left of the equal sign and right of equal sign then do the calculation separately. The calculation will look like this
-3x +2y = 7
-3x - 2y = 4
_____________ -
(-3x +2y) - (3x -2y) = 7 - 4
-3x + 2y + 3x + 2y = 3
4y= 3
y= = 0.75

Answer:
12 boxes per hour.
Step-by-step explanation:
Jake's family packed 22 boxes in 1 5/6 hours (that is, 1 hour plus 5/6 of a hour: 1 + 5/6 = (6+5)/6 = 11/6 hours).
So, to know the average number of boxes packed per hour, we can do a rule of three: If in 11/6 hours they packed 22 boxes, in 1 hours they packed X boxes.
22 boxes -> 11/6 hours
X boxes -> 1 hour
22/X = 11/6
X = 6 * 22 / 11 = 12
So, they packed an average of 12 boxes per hour.
cos x and sin x are sinusoids
X^2 is not
the answer is C.
