find the equation of a straight line passing through the point(4,5) and equally inclined to the lines 3x = 4y +7 and 5y= 12x +6
galina1969 [7]
<span>First we have to determine the slope of each lines by transforming to the slope-intercept form:

y=(3x-7/)4; m2= ¾y=(12x+6)/5, m3 = 12/5

The formula to be used in the proceeding steps is    a=tan^-1(m1-m2)/1+m1m2=tan^-1(m1-m2)/1+m1m2
substituting,      a=tan^-1(m1-3/4)/1+3m1/4=tan^-1(m1-12/5)1+12m1/5)     =>(4m1-3)/(4+3m1)=(5m1-12)/(5+12m1)m1 = -1applying this slope 

y -y1 = m(x-x1)
when y1 = 5 and x1 = 4 then,
y - 5 = -1(x-4)
y = -x +4+ 5 ; y = -x +9</span>

In triangle ABC, AC is a median. The value of AC is:<br><br> A. 34<br><br> B. 6 <br><br> C. 28
Levart [38]

x+2 = 28

x = 28-2 = 26


AC = X+8 = 26+8 = 34

Which expression is equivalent to square root 55x^7 y^6/11x^11 y^8? Assume x &gt; 0 and y &gt; 0.
morpeh [17]
The first step for solving this expression is to reduce the fraction with 11.
\sqrt{ \frac{5 x^{7} y^{6}  }{ x^{11}  y^{8} } }
Now reduce the fraction with x^{7}.
\sqrt{ \frac{5 y^{6} }{ x^{4} y^{8}  } }
Reduce the fraction one more time with y^{6}.
\sqrt{ \frac{5}{ x^{4} y^{2}  } }
To take the root of a fraction,, we must take the root of the numerator and denominator separately. This rule will change the expression to the following:
\frac{ \sqrt{5} }{ x^{2} y}
Since we cannot simplify this fraction any further,, the final answer is going to be \frac{ \sqrt{5} }{ x^{2} y}.
Let me know if you have any further questions.
