C, or 5000(0.9)t is correct.
Multiplying by 0.1 would not make the car’s price go down by ten percent, but 90. Hence, C is correct.
Hope this helps!
Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
x + y = 1 → (1)
2y - x = 8 → (2)
Adding the 2 equations term by term will eliminate the x- term
(x - x) + (y + 2y) = (1 + 8), that is
3y = 9 ( divide both sides by 3 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for y
Substituting y = 3 in (1)
x + 3 = 1 ( subtract 3 from both sides )
x = - 2
Solution is (- 2, 3 )
Answer:
70.6
Step-by-step explanation:
The mean is the average of a set of numbers.
To find it, add up all the terms and divide it by the number of terms.
70 + 67 + 79 + 66 + 64 + 80 + 64 + 75 = 565
565 / 8 = 70.625
Rounding this to the nearest tenth, we get an answer of 70.6
