There is only 1 real number solution
Answer:
$27
Step-by-step explanation:
Assuming this price list, ...
4 toy cars cost 6 dollars
6 toy cars cost 9 dollars
8 toy cars cost 12 dollars
We recognize that 18 cars is 3 times 6 cars, so the cost will be ...
cost of 18 cars = 3(cost of 6 cars) = 3($9) = $27
The cost of 18 toy cars is $27.
Addition is needed because of the subtraction sign.
42.081 * 99.91 ≈ 42 * 100 ≈ 4200

Answer:
f(x) = x² - 9x + 18
General Formulas and Concepts:
<u>Algebra I</u>
- Standard Form: ax² + bx + c = 0
- Binomial Roots: (x + a)(x + b)(x + c)(x + ...)
- Expanding by FOIL-ing (First, Outside, Inside, Last)
Step-by-step explanation:
<u>Step 1: Define</u>
Zeros/Roots x = 3, 6
<u>Step 2: Find Function</u>
- Rewrite Binomial Roots: f(x) = (x - 3)(x - 6)
- Expand by FOIL-ing: f(x) = x² - 6x - 3x + 18
- Combine like terms (x): f(x) = x² - 9x + 18
