Answer:
x=12°, ∡B=48°
Step-by-step explanation:
∡A=∡B
5x-12=2x+24
5x-2x=24+12
3x=36
x=12°
∡B=2*12+24°=48°
We can use the first and the last point of the table to find the average rate of change during the 40-minute talk time.
At t=0, the charges are $ 9.95
at t=40, the charges are $12.75
Average rate of change from t=0 to t=40 can be calculated as:
This means, the average rate of change is $0.07, meaning that for each minute of talk time, the monthly bill increases by $0.07. (Option B)
The value is 20. 10^2 = 100 and 5^1 = 5. 100/5=20
Answer:
x = 1/3 x=0
Step-by-step explanation:
y=6x-2
2=6x
2/6 = x
1/3=x
y=5x
5x=0
divide both sides by 5
0/5 = 0
