Which statement best explains why this expression is equal to 9.49.4?
9.4 + 9.4a(0)/-9.4

The given expression is

So, basically this expression would result in

The result would be just 9.4 because the product in the numerator of the fraction is null, because one of the factors is zero, and every number multiplied by zero equals zero, so the whole fraction expression is null because of that, that's why the answer is 9.4

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
