11. Which of these is a valid equation for all values of a and b? a. sqrt(a + b) = sqrt(a) + sqrt(b) b. sqrt(a + b) = sqrt(a) * sqrt(b) c. sqrt(ab) = sqrt(a) + sqrt(b) d. sqrt(ab) = sqrt(a) * sqrt(b)

it is c, trust i got your back lol

step-by-step explanation:

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

35 is an outlier
