Answer:

y=-\frac{5}{2}x-24

Step-by-step explanation:

2x-5y=-12\\5y=2x+12\\y=\frac{2}{5}x+\frac{12}{5}\\

if two lines perpendicular,

m_{1} .m_{2}=-1\\ \frac{2}{5} .m_{2}=-1\\m_{2}=-\frac{5}{2}

the line perpendicular to this line is

y=-\frac{5}{2}x+k ; k ∈ R

the line passes through the point (10,-1)

so,

-1=-\frac{5}{2} (10)+k\\-1=-25+k\\k=-24

∴the equation of the line perpendicular to 2x-5y=-12 that passes through the point (10,-1) is

y=-\frac{5}{2}x-24

Bad White [126]

Answer:

5.8%

Step-by-step explanation:

H= 1/r (in P - in A)

H=24

P=2000

A=5000

24= 1/r (in2000 - in5000)

24r = in 2000 - in 5000

r = in 2000 - in 5000
