A it is impossible because the line can only impact at a max of 2 points
Answer:
{4, - 1}
Step-by-step explanation:
Given
2y² - 6y - 8 = 0 ← in standard form
with a = 2, b = - 6, c = - 8
Using the quadratic formula to solve for y
y = ( - (- 6) ± 
) / (2 × 2)
= ( 6 ± 
) / 4
= ( 6 ± 
) / 4
= ( 6 ± 10 ) / 4
x = 
= 
= 4
OR
x = 
= 
= - 1
Solution is { 4, - 1 }
The function that describes the car's distance from little rocks would be option A; y = 45x + 280
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Point 1:
(x, y) = (0, 280)
Since we are told the car's initial position is 280 miles in the time 0 h
Point 2:
(x, y) = (4, 100)
Since we are told the car's final position is 100 miles after 4h.
Let's find the Slope :
m = 45
Now, the equation of the line is:
y = mx + b
y = 45x + 280
Then, The function that describes the car's distance from little rocks would be option A; y = 45x + 280
