Answer:
see below
Step-by-step explanation:
Starting with 50
Took out 20
50-20 = 30
Then the balance was 0
We need to subtract 30 to get to get to 0
30-30 = 0
Taking out 30
Withdrawing 30
Spending 30
All are ways of indicating taking out 30 dollars
Answer:
B -3.
Step-by-step explanation:
The slope = (y2-y1)/(x2-x1)
= (-2-4)/(8-6)
= -6/2
= -3.

Step-by-step explanation:
I just continually added the numbers til' I got 18,960 on Both Colleges.
Y=2
Since the table (y) increase by 2 each time the answer would be y=2
Answer:
√10 / 10
Step-by-step explanation:
tan θ > 0 and sin θ < 0, so θ is in quadrant III. That means cos θ < 0.
cos(θ + π/4)
Use angle sum formula.
cos θ cos(π/4) − sin θ sin(π/4)
½√2 cos θ − ½√2 sin θ
Factor.
½√2 cos θ (1 − tan θ)
½√2 cos θ (1 − 2)
-½√2 cos θ
Write in terms of secant.
-½√2 / sec θ
Use Pythagorean identity (remember that cos θ < 0).
-½√2 / -√(1 + tan²θ)
-½√2 / -√(1 + 2²)
½√2 / √5
√10 / 10
