Which algebraic expressions are polynomials? Check all that apply. Pi x minus StartRoot 3 EndRoot 5 y x2y 2 – 4x3 12y StartFraction 4 Over x EndFraction – x2 – 16 3. 9x3 – 4. 1x2 7. 3.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

answer: check all that apply, where the options?

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
