The value at the end of the year is 100% - 20% = 0.80 of the value at the beginning of the year. After 4 years of multiplying by this factor, the value is
$17,500·0.80⁴ = $7,168
Answer:
-2 19/20, 2 3/5. 3.125, 10.35
Step-by-step explanation:
Let's solve each expression:
Solve:
-4.5 x -2.3
Multiply:
-4.5 x -2.3
10.35
Therefore, the simplified expression is 10.35
Solve:
5/-1.6
Divide:
5/-1.6
3.125
Therefore, the simplified expression is 3.125
Solve:
5 6/15 + (-2 4/5)
First, make the denominators of 4/5 equal to 15:
4/5 = ?/15
Multiply both the numerator and denominator by 3:
4 x 3 = 12
5 x 3 = 15
The new fraction is 12/15.
Add:
5 6/15 + (-2 12/15)
2 9/15
Simplify:
2 9/15 = 2 3/5
(divide the numerator and denominator by 3)
Therefore, the simplified expression is 2 and three-fifths.
Solve:
-3 3/10 - (-7/20)
First, make the denominators of 3/10 equal to 20:
3/10 = ?/20
Multiply both the numerator and denominator by 2:
3 x 2 = 6
10 x 3 = 20
The new fraction is 6/20.
Subtract:
-3 6/20 - (-7/20)
-2 19/20
Therefore, the simplified expression is negative 2 and nineteen-twentieths.
Order from least to greatest:
-2 19/20, 2 3/5. 3.125, 10.35
Functions cannot have the same X value (the first number), but they can have the same Y value (the second number).
<span>A. {(1,2),(2,3),(3,4),(2,1),(1,0)}
B. {(2,−8),(6,4),(−3,9),(2,0),(−5,3)}
C. {(1,−3),(1,−1),(1,1),(1,3),(1,5)}
D. {(−2,5),(7,5),(−4,0),(3,1),(0,−6)}
Choice A. has two repeating X values [(1,2) and (1,0), (2,3) and (2,1)]
Choice B. has one repeating X value [(2, -8) and (2,0)]
Choice C. all has a repeating X value (1)
Choice D doesn't have any repeating X values.
In short, your answer would be choice D [</span><span>{(−2,5),(7,5),(−4,0),(3,1),(0,−6)}] because it does not have any repeating X values.</span>
