3. Find the value of a and b when 5+√6/5-√6 = a+b√6

mr Goodwill [35]

The answer for A is,

$a = 5 + \frac{ \sqrt{6} }{ \sqrt{5} } - \sqrt{6} - \sqrt{6b}$

And the answer for B is,

$b = - 1 + \frac{5 + \frac{ \sqrt{6} }{ \sqrt{5} } - a }{ \sqrt{6} }$

hope it helps.

sorry of its wrong.

AleksandrR [38]

52 can be broken down to the following
2*26 =52
2*(2*13) <---13 x 2=26 x 2=52
2*2*13 or 2^2*13 <--BOTH mean the same thing :)

Determine the equation of the line with slope 3/4 passing through the point 4,0

Vitek1552 [10]

Answer:

$y = \frac{3}{4}x - 3$

Step-by-step explanation:

If it has a slope of 3/4, then it will look like this:

$y = \frac{3}{4}x + b$

If it passes through (4, 0), than y = 0 when x = 4

$y = \frac{3}{4}(4) + b$

$y = 3 + b$

$b = -3$

Therefore, the equation is $y = \frac{3}{4}x - 3$ .
