Ineed asap the answer choices $1,300 .  $1,500  .  $3,300 .    $4,300 .    $4800/1 copier .      -$500/1 year .    v(x) = −500x + 4800 .    v(x) = 500x + 4800 a copier purchased new for $4,800 depreciates in value $500 each year. 1. the function that models this equation is . 2. the rate of change for the function is . 3. the model predicts that the value of the copier after 3 years will be . 4. the model predicts that the value of the copier after 7 years will be .

1. The function that models this equation is:

Since the value V (x) of the copier depreciates over time, hence the 500 must be negative, therefore the equation:

V(x) = −500x + 4800

2. The rate of change for the function is:

The rate of change is also equivalent to the slope of the equation, in this case the slope is equal to:

-$500/1 year

3. The model predicts that the value of the copier after 3 years will be:

Substituting the value of x = 3 to the function gives us:

V(x) = −500 (3) + 4800

V(x) = $3,300

4. The model predicts that the value of the copier after 7 years will be:

Substituting the value of x = 7 to the function gives us:

V(x) = −500 (7) + 4800

V(x) = $1,300

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
