Answer:
<h3>1/2</h3>
Step-by-step explanation:
Given the expression
4/5 x - 1/10 = 3/10
We are to find the value of x
4/5 x = 3/10 + 1/10
4/5 x = 4/10
Cross multiply
4x * 10 = 5 * 4
40x = 20
x = 20/40
x = 1/2
The value of x is 1/2
Y=1/2x-4
Perpendicular means it is opposite and the reciprocal. 1/2(4) = 2-4 equals -2.
