Answer:
A
Step-by-step explanation:
because if you divied 100 by 400 it is a lot less than the others
The expression that has the least value when x is 400 would be 10/x.
A linear equation is an equation in which the highest power of the given variable is always 1. The standard form of a linear equation in one variable is of the form Ax + B = 0.
A. 100/x
100 / 400 = 0.25
B. 10/x
10/ 400 = 0.025
C. 100-x
100 - 400 = - 300
D. 10-x
10 - 400 = -390
Thus, the least value is o.o25.
