2x ( -2x -3)
2x + 4y = 450
2x + 4y = 315
3x + 4y = 450
y = 8.40 + x
y = 8.40x + 58
y = 8.40x
y = 8.40x - 58
x+y=87
1.5x+0.5y=87
1.5x+0.5y=87
x+y=87
7x + 2y = 24
8x + 2y = 30
Solve for y
-4x + 2y = -6
y = -2x + 3
y = 2x + 3
y = 2x - 3
y = -2x - 3
Which equation describes the story below?
You start with $5 and triple your money every day.
y=5(3)x
y=5x
y=5(3x)
y=15x
Write an exponential function to model the situation. Then solve.
The cost of tuition at a college is $12,000 and is increasing at a rate of 6% per year. What will the cost be after 4 years?
C(t) = 12000(1.06)t ; $3149.72
C(t) = 12000(.06)t ; $3149.72
C(t) = 12000(.06)t ; $1472.95
C(t) = 12000(1.06)t ; $15149.72
A particular type of cell triples in number every hour. Which function can be used to find the number of cells present at the end of h hours if there are initially 6 of these cells?
f(h) = 3(6)h
f(h) = 6xh
f(h) = 6(3)h
f(h) = 3(6h)
The amount of cola in a soda machine decreases by a rate of 5% each hour. The amount of cola in the machine was originally 75 gallons.
Which function models the amount of cola in gallons after h hours?
f(h) = 75(-5)h
f(h) = -5(75)h
f(h) = .95(75)h
f(h) = 75(.95)h
The function y = 24,220 (0.85)x represents Mr. Bittle's investment in the stock exchange where x is measured in months.
Which statement is NOT true.
Mr. Bittle loses 85% of his investment monthly
Mr. Bittle initially invested $24,220
Each month Mr. Bittle loses 15% of his investment
Write an exponential function to model the situation. You invest $1500. Your investment increases at a rate of 3.5%.
B(t) = 1500(0.965)t
B(t) = 1500(1.035)t
B(t) = 1500(.035)t
B(t) = 1500(1.965)t
Write an exponential function to model the situation. The value of a car is $18000 and is depreciating at a rate of 12% per year.
V(t) = .88(18000)t
V(t) = .12(18000)t
V(t) = 18000(.88)t
V(t) = 18000(.12)t

The value of a car is $15,000 and depreciates at a rate of 8% per year. What is the exponential equation that models this situation?
y = 8(15,000)x
y = 15,000(1.08)x
y = 15,000(0.92)x
y = 15,000(0.08)x
Determine if the equation y = 15(1.35)x represents exponential growth or decay and justify. Hint: Think about the growth and decay equations.
Growth, because the scale factor is greater than 1
Growth, because the scale factor is less than 1
Decay, because the scale factor is greater than 1
Decay, because the scale factor is less than 1
Write an exponential function to model the situation. Then solve.
The value of a car is $18000 and is depreciating at a rate of 12% per year. What will the value of the car be after 10 years?
V(t) = 18000(.88)t ; $12986.98
V(t) = 18000(.12)t ; $12986.98
V(t) = 18000(.88)t ; $5013.02
V(t) = 18000(.12)t ; $5013.02
