Answer:
6.06 x
Step-by-step explanation:
(5.25 x
) / (8.7 x
)
= (5.25 x
) x(
)/ (8.7 )
= (5.25 x
)/ (8.7 )
= 0.606 x
= 6.06 x
Given:

Solution:
We have,

Putting
, we get



On combining like terms, we get


Therefore, the required function is
.
Step-by-step explanation:
4x + 2xy=
4×4 + 2×4×-3
= 16 + (-24)
= - 8
Answer:
-2x + 6
Step-by-step explanation:
Step 1: Write expression
3(x + 2) - 5x
Step 2: Distribute
3x + 6 - 5x
Step 3: Combine like terms
-2x + 6
Let the value of the vehicle be described by the equation
V = a + bx
where x = number of years since purchase
a,b are constants.
When x = 0, V = $7500. Therefore
a + b*0 = 7500
a = 7500
When x = 7, V = $500. Therefore
7500 + 7b = 500
7b = 500 -7500 = -7000
b = -7000/7 = -1000
The equation is
V = 7500 - 1000x
The slope of this equation is the depreciation rate, and it is -$1000 per year.
Answer: $1000 depreciation per year.
