This question makes no complete sense b
Answer:
10
Step-by-step explanation:
The y-intercept for each line is...
y=2x+7 (0, 7)
y=2x-3 (0, -3)
Note this is because...
y=mx+b
b represents the y-intercept
Using the distance formula...
Answer:
p-parenthesis
e- exponent
m- multiplication
d- division
a- addition
s- subtraction
Step-by-step explanation:
Equation in slope-intercept form:
y=mx+b
m=slope
b=y-intercept
Data:
m=-32
b=7
Therefore:
y=-32x+7
Answer: y=-32x+7
Answer:
26. 106
27. -7.9% per year
28. shrinking
29. 31
30. $9560.92
31. $8243.61
Step-by-step explanation:
26. The value when t=0 is 106·.921^0 = 106·1 = 106
__
27. The rate of change is 0.921 -1 = -0.079 = -7.9% per year. It is a good idea to put the sign with the rate of change, so you know whether it is increasing or decreasing. Also, units are a good idea: "per year."
__
28. The negative rate of change means the population is shrinking.
__
29. In 15 years ...
y = 106·0.921^15 ≈ 30.8 ≈ 31
In 15 years the deer population is predicted to be 31 deer.
__
30. $5000(1 +.065/12)^(12·10) ≈ $9560.92 . . . . units are a good idea (dollars)
__
31. $5000·e^(.05·10) ≈ $8243.61 . . . . the exponential term has a time multiplier

Numbers are correct. IMO, some details need attention.
