PLZ ANSWER QUICKLY (edgenuity 2020) The graph shows the price of a good compared to the quantity demanded and the quantity supplied. A graph titled Price Controls Graph 1 has Quantity on the x-axis and price on the y-axis. Demand has a negative slope and supply has a positive slope. Points are on the demand line and the supply line at the same price. Excess demand is indicated between the 2 points. Both points are below the point of equilibrium. On this graph, what does the green arrow represent? an ineffective price floor set above equilibrium causing a surplus. an effective price floor set below equilibrium causing a shortage. an ineffective price ceiling set above equilibrium causing a surplus. an effective price ceiling set below equilibrium causing a shortage.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
