Answer:
A and C
Step-by-step explanation:
The distance between P and Q is 14.
With the first one the absolute value is of -8 is 8 and 8+5 is 14 so that's right.
The third one subtracting a negative is like adding a positive. So it would be 5+8 which is also 14.
The other to equal 3 and -3 which is wrong.

10 18
20 36
30 54
40 72
50 90
<span>If the tip varies directly with the number of guests, which equation represents the relationship between the tip, t, and the number of guests, g?
t = 1.8g t = g/18 g = 1.8t g = t/18
</span>
18/10 = 1.8
36/20 = 1.8
54/30 = 1.8
direct variation: <span>t = 1.8g</span>
Answer:
{π/4, 5π/4}
Step-by-step explanation:
Tan theta -1=0 could be rewritten as tan Ф = 1. The tangent function is 1 at Ф = π/4. As the period of the tangent function is π,
tan Ф = 1 will be true for Ф = π/4 + π, or (5/4)π.
The solution set is {π/4, 5π/4}.
