Answer:
x = 
Step-by-step explanation:
We have the equation: 3 + 
= 
Move the constant (in this case the constant is 3) to the right side of the equation, changing its sign
= - 3
Calculate the difference.
= 
Divide.
(when dividing two fractions, you can change it to a multiplication problem by switching the numerator and denominator of the divisor.)
So, we get the equation x 
which is .
I hope this helps!
Answer:
Step-by-step explanation:
(x - 5)(x-4)
= x(x) - 4(x) - 5(x) - 4(-5)
= x^2 - 4x - 5x + 20
= x^2 - 9x + 20
Answer:
(26,-2)
Step-by-step explanation:
For any two points on coordinate plane (x1,y1) and ( x2,y2)
coordinate of midpoint is given by (x1+x2)/2 , (y1+y2)/2
Given
(x1,y1) = (-4,-8)
midpoint : (11,-5)
let other point be x2 and y2
therefor by using formula for midpoint coordinate given above we have
midpoint : (11,-5) = (-4+x2)/2 , (-8+y2)/2
Hence point
11 will be equivalent to (-4+x2)/2
11 = (-4+x2)/2
=> 11*2 = -4+x2
=>22 + 4 = x2
=>x2 = 26
similarly
-5 will be equal to (-8+y2)/2
-5 = (-8+y2)/2
=> -5*2 = -8+y2
=> -10 + 8 = y2
=> y2 = -2
Therefore coordinates of other point is (26,-2).
Step-by-step explanation:
conditions : x≠0 and x≠-a and b≠1
1/(x+a) = b/x ⇌ 1×x = b(x+a) ⇌ x = bx + ba ⇌ (1-b)x = ab ⇌ x = ab/(1-b)
