Every year after a new car is
slavikrds [6]

Answer: The value of the car after 3 years is $5,333.333

And no, the relationship is not linear, is an exponential decay.

Step-by-step explanation:

We know that every year, the car loses 1/3 of its value.

So if the initial value of the car is V.

After one year, the new value of the car will be:

Value (1 year) = V - (1/3)*V = (2/3)*V

After another year, the value will be:

Value (2 years) = (2/3)*V - (1/3)*(2/3)*V = V*(2/3)^2

Ok, we already can see that this is an exponential decay.

(So no, this is not a linear relationship).

The value equation as a function of the number of years will be:

Value(N) = V*(2/3)^N

Then if the initial cost of a car is $18,000, and we want to know its value after 3 years, we need to replace V by $18,000 and N by 3 in the above equation:

Value(3) = $18,000*(2/3)^3 = $5,333.333

KIM [24]

Answer:

13. -28 = p

12. 5 = r

11. -12 = t

10. -8 = q

9. -77 = s

8. 9 = w

7. 12 = y

6. 3 = a

5. 9 = n

4. 3 = x

3. 12 = y

2. 5 = c

1. 5 = m

DON'T GET HOOKED

Step-by-step explanation:

13. 1 + p \div 7 = -3 \\ \\ p\div 7 = -4 \\ \\ -28 = p

12. 5[r + 4] = 45 \\ \\ r + 4 = 9 \\ \\ 5 = r

11. t \div 4 - 3 = -6 \\ \\ t \div 4 = -3 \\ \\ -12 = t

10. -4 + 11q = -92 \\ \\ 11q = -88 \\ \\ -8 = q

9. s \div 7 + 8 = -3 \\ \\ s \div 7 = -11 \\ \\ -77 = s

8. w \div 3 + 3 = 6 \\ \\ w \div 3 = 3 \\ \\ 9 = w

7. y \div 3 - 4 = 0 \\ \\ y \div 3 = 4 \\ \\ 12 = y

6. 3[a + 5] = 24 \\ \\ a + 5 = 8 \\ \\ 3 = a

5. 14 = 2n - 4 \\ \\ 18 = 2n \\ \\ 9 = n

4. 3x + 6 = 15 \\ \\ 3x = 9 \\ \\ 3 = x

3. 6y - 11 = 61 \\ \\ 6y = 72 \\ \\ 12 = y

2. 9c - 4 = 41 \\ \\ 9c = 45 \\ \\ 5 = c

1. 2m + 2 = 12 \\ \\ 2m = 10 \\ \\ 5 = m

PLEASE HELP ASAP 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER
Aloiza [94]

Answer:

7 -5i

Step-by-step explanation:

The additive inverse is the number we add to make it equal to zero

-7+5i + x = 0

the real part

-7 + x = 0

x = 7

The imaginary part

5i+x = 0

x = -5i

The complex x is

7 -5i

Notice it is the opposite of the number

- (-7+5i)

7-5i
