Answer:
Equation of the parabola: or
Vertex form:
Intercept form:Step-by-step explanation:
8x^3 -5x^2 + 8x + 9+5x^3 + 3x^2 - 5x + 4 =
8x^3+5x^3-5x^2 + 3x^2+ 8x - 5x+ 9<span>+ 4 = </span>
13x^3-2x^2+3x+13
8 coins = $0.93
3 quarters = $0.75
1 dime = $0.10
1 nickel = $0.05
3 pennies = $0.03
3 + 1 + 1 + 3 = 8 coins
$0.75 + $0.10 + $0.05 + $0.03 = $0.93
The green line is LM
The red line is JM
The blue point is at the coordinates (2/3, -14/3)
you'll have to excuse the way my graph looks. my graphing application on my computer is weird
