Answer:
c. sin 30 is positive and sin -30 is negative
Step-by-step explanation:
Picture the unit circle (which is attached). <u>Sine is like the y-coordinate.</u> And -30 and 30 on the unit circle both form equally-sized triangles, but -30 is underneath the x-axis, so it has a <u>negative y-coordinate.</u> 30 is above the x-axis, so it has a <u>positive y-coordinate.</u>

Answer:
x = 2, y = 23
x = 3, y = 39
x = 4, y = 56
x = 5, y = 67
Step-by-step explanation:
Given:
14x - 3 where $14 is per hours on part-time work and $3 is cost to and from work.
y = 14(2) - 3
y = 28 - 3
y = 23
y = 14(3) - 3
y = 42 - 3
y = 39
y = 14(4) - 3
y = 56 - 3
y = 53
y = 14(5) - 3
y = 70 - 3
y = 67
x = 2, y = 23
x = 3, y = 39
x = 4, y = 56
x = 5, y = 67
