Answer:
Step-by-step explanation:
you have to use trigonometric functions
cos 30 = adj. /hyp.
cos 30 = 12 / y
y = 12/cos 30 ≅13.86
tan 30 = opp./adj
tan30 = x / 12
x = 12 tan30 ≅6.93
Answer:
-6
Step-by-step explanation:
x-intercept is y = 0, so the point is (-6, 0), answer is -6
64 less than y = y-64
no less = greater or equal than
negative 128 = -128
y-64 ≥ -128
Add 64 to both sides of the inequality:
y-64+64 ≥ -128+64
y ≥ -64
interval :
[-64,∞)
