Answer:
two points where the line is directly on them are (-3, -2) and (0, 3)
to find the slope you do rise/ run
so start at the first point and count up and right to the second. you'll count up 5 units and right 3 units. so the slope is 5/3
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
a 4 side polygon has 360° interior angle
120 +120=240
360-240=120
120÷2=60
60÷6=10
Answer:
The correct answer would be 5v + 30.
Answer:
43,872
Step-by-step explanation:
The growth of cell phone subscribers in Centerville can be modeled by an exponential function.
y = ab^x . . . . . where a = initial value, b = growth factor
The growth rate is given as 75% per year, so x will have units of years. It will be zero for the year 1985. The growth factor is ...
b = 1 + growth rate = 1 +0.75 = 1.75
Then the model is ...
y = 285·1.75^x
__
For x = 1994 -1985 = 9, the number of subscribers is modeled as ...
y = 285·1.75^9 ≈ 43,872
The model predicts 43,872 cell phone subscribers in 1994.
