In a song competition, a participant has to score a total of at least 20 points in the first four rounds combined to move on to the fifth and final round. curtis scored 2 points in the first round. he then went on to score additional points in the second, third, and fourth rounds. in each of those rounds, his score was identical. which inequality best shows the number of points, p, that curtis scored in each of the second, third, and fourth rounds if he earned a place in the finals?

Step-by-step explanation:

Given that in a song competition, a participant has to score a total of at least 20 points in the first four rounds combined to move on to the fifth and final round.

Curtis scored 2 points in the I round.  He then went on to score additional points in the second, third, and fourth rounds

Let p be the identical point in II, III and IV round.

Then total of four rounds Curtis scored = 2+3p

Since he got selected for the finals, we have

32

step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
