I think the answer is B The region shaded below a solid boundary line. I'm only 75% sure
Answer:
D (-1, 5)
Step-by-step explanation:
In reflection along the x-axis,
x-coordonate remains unchanged and y-coordinate gets multiplied by -1
Given:
Cost of printing a catalog: flat rate of $52 and $0.20 per copy.
C = 52 + 0.20x
C is the total cost of printing x number of copies.
x = 500
C = 52 + 0.20(500) = 52 + 100 = 152
x = 1000
C = 52 + 0.20(1000) = 52 + 200 = 252
x = 1500
C = 52 + 0.20(1500) = 52 + 300 = 352
x = 2000
C = 52 + 0.20(2000) = 52 + 400 = 452
x = 2500
C = 52 + 0.20(2500) = 52 + 500 = 552
Answer:
11x+y = -28
Step-by-step explanation:
We have two points so we can find the slope
m = (y2-y2)/(x2-x1)
= (-6-5)/ (-2--3)
= -11(-2+3)
= -11/1
The slope is -11
We can use point slope to make an equation
y-y1 = m (x-x1)
y-5 = -11(x--3)
y -5 = -11(x+3)
Distribute
y-5 = -11x-33
Add 5 to each side
y-5+5 = -11x-33+5
y = -11x-28
Add 11x to each side
11x+y = -11x+11x-28
11x+y = -28
This is the standard form of a line

Answer:
- car value: $4,953.84
- population: 446
- maybe not
Step-by-step explanation:
All of these exponential function problems use the same equation, but with different plug-in values. These can be easily accommodated by a spreadsheet or graphing calculator.
The general form of the value after t years is ...
(initial value)×(1 +annual growth rate)^(years)
The growth rate is positive for an increase, negative for a decrease.
a) Initial value: 22385; growth rate: -0.14; years: 10
value after 10 years: $22385×(1-0.14)^10 = $4953.84
__
b) initial value: 290; growth rate: 0.09; years: 5
population after 5 years: 290(1+.09)^5 = 446
__
c) initial value: $4000; growth rate: -0.10; years: 8
value after 8 years: $4000(1 -0.10)^8 = $1721.86
Selling the car for $1500 is selling it for <em>less than its estimated value</em>. That may not be a good decision.
_____
<em>Additional comment</em>
The property value of the car is not the only consideration when evaluating the sale. Other costs related to the car may come into play, and there may be tax implications.
