The mistake is “there are”
Answer:
y= 3- x/3
Step-by-step explanation:
To find the inverse function, swap x and y, and solve the resulting equation for x.
If the initial function is not one-to-one, then there will be more than one inverse.
So, swap the variables: y=9−3x so it becomes x=9−3y.
Now, solve the equation x=9−3y for y. You would just need to leave y alone so you divide by 3 on both sides (NOT negative 3. Just 3.)
Answer:
$141,557.76
Step-by-step explanation:
Chao bought a boat for 160,000
The value of the boat reduces by 4% every year
Therefore the value of the most at the end of three years can be calculated as follows
= 100%- 4%
= 96%
= 160,000 × 96/100^3
= 160,000 × 0.96^3
= 160,000 × 0.884736
= 141,557.76
Hence the price of the boat after 3 years is 141,557.76
Simplifying the expression (x - 2y) + (3x + 4y).
Work:
(x - 2y) + (3x + 4y)
Combine like terms.
x + 3x = 4x
-2y + 4y = 2y
Reform the expression.
4x + 2y
Simplified Expression: 4x + 2y.
