General form is ax^2 + bx + c = 0
so comparing the equation in the question to this we get:-
a = 1, b = -3 and c = -2 Answer
Answer: I think the Answer is 36 Let me know if i'm Right.
If something is to the power of 1/2, it is the same as the square root of that number. So, what's the square root of 49?
Answer:
12
Step-by-step explanation:
Y=ax+b, y=cx+d (a≠0, c≠0)
If the two line cross perpendicularly ⇔ ac= -1
So a tangent of the perpendicular line is "-(1/5)".
Then, the equation of the perpendicular line is y=-(1/5)x+a (a is <span> y-intercept</span>).
On the other hand, this equation pass r(1, 3), so
3 = -(1/5) times 1 + a
∴ a=16 / 5
Therefore, y=-(1/5)x+16 /5 is answer.
By the way, I'm Japanese so if you find some mistakes in my English, please let me know.
