(-2d² + s)(5d² - 6s)
<u>Step 2: Expand</u>
- FOIL: -10d⁴ + 12d²s + 5d²s - 6s²
- Combine like terms: -10d⁴ + 17d²s - 6s²
Answer:
(a). Assuming consumption is only dependent upon miles driven, the function is defined as :
Amount of gas left after driving x miles :
(b). The y-intercept is obviously 10. This represents the initial gas in the tank, 10 gallons.
(c). The x-intercept is the solution to
The x-intercept is 250. It represents the "distance taken by car to empty the tank".
The value a is 7.
<h3>What is Straight Line?</h3>
A line is simply an object in geometry that is characterized under zero width object that extends on both sides. A straight line is just a line with no curves.
Here, the given equation of line
y = ax -3
line passing through point (2, 11), then
11 = a X 2 - 3
11 + 3 = 2a
2a = 14
a = 7
Thus, the value a is 7.
