Y = 3x - 4
y = 3(-1) - 4
y = -3 - 4 = -7
Graph pair is (-1, -7)
y = 3(0) - 4
y = 0 - 4 = -4
Graph pair is (0, -4)
y = 3(2) - 4
y = 6 - 4 = 2
Graph pair is (2, 2)
y = 3(4) - 4
y = 12 - 4 = 8
Graph pair is (4, 8)
The volume of the refrigerator would be 30
If the probability of spinning an A once is 1/12, then the probability of spinning an A 3 times is 3 × 1/12.
3 × 1/12 = 3/36
Simplify
3/36 = 1/12
Hi there!

The two trapezoids are similar, so we can determine a common scale factor:
OL/UR = NM/TS
9/3 = 6/2
3 = 3
Trapezoid ONML is 3x larger than UTSR, so:
RS = 4, LM = y
3RS = LM
3 · 4 = y = 12.
Find x using the same method:
3UT = ON
3(2x+1) = 4x + 9
6x + 3 = 4x + 9
2x = 6
x = 3.
4/16 and 1/4 happy to help :)
