Answer:
(5√12)/12
Step-by-step explanation:
In general, 1/√a can be rationalized as (√a)/a. That is the denominator can be multiplied by the square root of the same number to rationalize it. The numerator needs to be multiplied by the same square root.
Answer:
x = 5/4 + √65/4 or x = 5/4 - √65/4
Step-by-step explanation:
I'm assuming you mean 2x^2-5x-5=0?
x = ( -b ± √b^2 - 4ac ) / 2a
x = ( -(-5) ± √(-5)^2 - 4(2)(-5) ) / 2(2)
x = ( 5 ± √(25 + 40) ) / 4
x = ( 5 ± √65 ) / 4
x = 5/4 ± √65/4
Therefore, x = 5/4 + √65/4 or x = 5/4 - √65/4
Answer:
y=4x-1
Step-by-step explanation:
Remember the point slope form equation y-y1=m(x-x1) where m is the slope and the given point is (x1,y1)
y-7=4(x-2) . Plug in the numbers for the equation
y-7=4x-8 distributive property
y = 4x-1
