Answer:
Step-by-step explanation:
(3,4) ; (6,-1)
slope = y₂ - y₁ / x₂-x₁
= -1 - 4 / 6-3
= -5/3
Answer:
The quadratic equation 3x² - 12x + 9 = 0 has two real roots when solved:
x₁ = 1 and x₂ = 3
Step-by-step explanation:
✍ An equation of type ax² + bx + c = 0, can be solved, for example, using the quadratic formula:
either
where
Identify the coefficients
a = 3, b = -12 and c = 9
Calculate the discriminant value
Δ = b² - 4ac
Δ = (-12)² - 4.3.9 = 144 - 12.9
Δ = 144 - 108 = 36
Enter the values of a, b and the discriminant value in the quadratic formula
As we can see above, the discriminant (Δ) of this equation is positive (Δ> 0) which means that there are two real roots (two solutions), x₁ and x₂.
To find x₁, just choose the positive sign before the square root. Later,
Answer:
they tried 24 times
Step-by-step explanation:
you have find out how many shots they made and then find out what times three equals that
The perpendicular slope is undefined because the slope for the given line is zero. 1/0 has no meaning at least for this problem.
y = 5 would be parallel. Any number could be put in there even a transcendental.
y = pi. is parallel to y = - 8
x = 3 would be perpendicular to y=-8
The two lines would meet at (3,8)
