No, I ask about the normal stress in Y , why its 0 

incorrect. 

the point of intersection is ( 1.75,5 ) 

4x-2=5

4x=7

x=1.75 

this is how to find x .

to find y substitute the value of x in any equation. 

y = 4(1.75)-2 

y = 5 

$(\frac{2}{5})^4 = \frac{2^4}{5^4} = \frac{16}{625}=0.0256$

$20/30 = 60/x$

$x= \frac{30*60}{20}$

x = 90

so in 60 min he will travel 90 meters 

You are welcome Hayley :) 

and its xvxvxv Not xvxvxvxv 

This one. 

Solve for x 

$5(x-2)=3x$

$5x-10=3x$

$5x-3x=10$

$2x=10$

$x=10/2$

$x=5$

I accept 

Don't listen to them, You are the best. :) 

No problem, 

waiting fo Alan.
