Which equation is not a linear equation?
a)
x = -5
b)
–4v + 2w = 7
c)
x4= y
d)
2/x + 3/y = 5

2/x + 3/y = 5

Step-by-step explanation:

A linear equation refers to any equation that can be written in the form;

ax+b=0 or y - mx -c = 0

The graph of a linear equation will always be a straight line; Vertical, horizontal or with a given degree of steepness (slope).

All the equations given are linear, except the last equation;

2/x + 3/y = 5. The exponents of the variables x and y is not 1 hence the equation is non-linear. Find the graph attached;

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

8121 because

130,000 divided by 16 is 8121
