The product of 9 and the sum of three more than a number. 9(3+n)
Answer:
x = -2bm/(m²+1)
Step-by-step explanation:
One line has equation
... y = mx + b
The slope of the perpendicular line is the negative reciprocal of the slope of the original line. The perpendicular line with the opposite y-intercept has equation
... y = (-1/m)x - b
The point of intersection is where the x- and y-values are equal, so ...
... mx + b = (-1/m)x - b
... (m +1/m)x = -2b . . . . . . . add 1/m - b to both sides
... (m²+1)x = -2bm . . . . . . . multiply by m
... x = -2bm/(m²+1) . . . . . . divide by the coefficient of x
Answer:
Hope this helps you to understand, to do the problem and for future problems!
Step-by-step explanation:
All you have to do is take the numbers, add them, then divide them by how much there are. Once you did that if its a negative you just turn it positive bc its absolute.
