Answer:
No real
solution
Step-by-step explanation:
Firstly, let us check if we would be having a real solution
We start by rewriting the equation
We have this as;
8x^2 -25x + 24 = 0
We proceed to get the discriminant
Mathematically, we have this as;
D = b^2 - 4ac
b is the coefficient of x which is -25
a is the coefficient of x^2 which is 8
c is the last number which is 24
So we have;
D = (-25)^2 - 4(8)(24)
D = 625 - 768 = -143
Since the value of the discriminant is negative, there cannot be real roots
What we have as solution are complex roots
Answer: When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). ... the line y = x is the point (y, x). The reflection of the point (x,y) across. the line y = -x is the point (-y, -x).
Step-by-step explanation: I hope this helped! Actually, I just hope that my answer is correct but whatevs lol :)
Answer:
it A
Step-by-step explanation:
Answer
cos c = 40/41
Step by step explanation
It is a right triangle.
AB^2 + BC^2 = AC^2
9^2 + 40^2 = 41^2
81 + 1600 = 1681
1681 = 1681
Cos C = Opposite/Hypotenuse
Cos C = 40/41 [opposite = 40 and Hypotenuse = 41]
Thank you.
