Answer:
y = - 5x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Here m = - 5 and b = 7, thus
y = - 5x + 7 ← equation of line
Answer: $3.87
Step-by-step explanation:
3.10 increase 24.8% =
3.10 × (1 + 24.8%) = 3.10 × (1 + 0.248) = 3.8688

Answer:</h2>
The expression which represents the perimeter P of the rectangle as a function of L is:

<h2>
Step-by-step explanation:</h2>
The length and width of a rectangle are denoted by L and W respectively.
Also the diagonal of a rectangle is: 10 inches.
We know that the diagonal of a rectangle in terms of L and W are given by:

( Since, the diagonal of a rectangle act as a hypotenuse of the right angled triangle and we use the Pythagorean Theorem )
Hence, we have:

But we know that width can't be negative. It has to be greater than 0.
Hence, we have:

Now, we know that the Perimeter of a rectangle is given by:

Here we have:

Answer:
$5,415.49
Step-by-step explanation:
Cost of the boat = $16,500
Decrease in value per year = 13%
Worth of the boat in 8 years = ?
Remaining value = 100% - 13%
= 87%
Worth of the boat in 8 years = cost of the boat × remaining value^8
= $16,500 × 87%^8
= $16,500 × 87/100^8
= $16,500 × 0.87^8
= $16,500 × 0.3282116715437121
= $5,415.49
The worth of the boat after 8 years = $5,415.49
