It would be 25 multiplied by 3 because in the question 25 is before 3. Also wouldn't 25 before 3 just make more sense? <span />
Answer:
<h2>3</h2>
Step-by-step explanation:
<h3>Step 1: Identify two points on the line</h3>
1,2 & 2,5
<h3>Step 2: Select x1, y1 & x2, y2</h3>
x1 = 2, y1 = 5 x2 = 1, y2 = 2
<h3>Step 3: Use the Slope Formula</h3>
change y/ change x
<u><em>IMPORTANT: it is change in y over change in x, not the other way around. It will be wrong if done the other way, though that would seem to be more logical, since x is the first variable in the pair.</em></u>
Y 5 -2 = 3
X 2 - 1 = 1
3/1 = 3

Answer:
x ∈ {-a, -b}
Step-by-step explanation:
1/(a+b+x) = 1/a +1/b +1/x . . . . given
abx = bx(a+b+x) +ax(a+b+x) +ab(a+b+x) . . . . multiply by abx(a+b+x)
(a+b)x^2 +(a+b)^2x +ab(a+b) = 0 . . . . . subtract abx
x^2 + (a+b)x +ab = 0 . . . . . divide by (a+b)
This is a quadratic equation in x. It will have two solutions, as given by the quadratic formula.
x = (-(a+b) ±√((a+b)^2 -4(1)(ab))/(2(1)) = (-(a+b) ± |a -b|)/2
Without loss of generality, we can assume a ≥ b, so |a -b| ≥ 0. Then ...
x = (-a -b -a +b)/2 = -a
x = (-a -b +a -b)/2 = -b
There are two solutions: x ∈ {-a, -b}.
