Find the equation of the line that is perpendicular to y = - 1/3 x + 2 and passes though the point (-5,2)
elena55 [62]

Answer:

y - 2 = 3(x + 5)

Step-by-step explanation:

The given equation has slope -1/3.  Any line perpendicular to the given line has a slope which is the negative reciprocal of -1/3, which comes out to +3.

Use the point-slope formula y - k = m(x - h):

y - 2 = 3(x + 5)

Can someone help me out ? Don't just guess the answer :(
Monica [59]
1) 2m+6 / m² + 7m - 12  +  (m+2)/(m+4)

= 2(m+3) / (m+4)(m+3)  + (m+2)/(m+4)

= 2/(m+4) + (m+2)/(m+4)

= 2+m+2 / (m+4)

= m+4 / m+4

= 1  [ Option A ]

Answer 2) 3/ (x+4)  + 7/ (x-3)

=  3(x-3) + 7(x+4)/ (x² +x - 12)

= 3x-9 + 7x + 28 / (x² +x - 12)

= 10x + 19 / (x² +x - 12)  [ Option A ]

Hope this helps!
