3. Pearl wants to determine the average number of goals she scored her first five
field hockey games of the season. She
scored 2 goals in the first game, 3 goals in
the second, and 5 goals in the third. She
can't remember how many goals she
scored in the fourth and fifth games but
she does remember that she scored the
same number of times in each of those
2+3+5+X+X
games. The expression
5
will determine the average number of
goals she scored, where x is the number
of goals she scored in each of the fourth
and fifth games.
If Pearl scored 2 goals in each of the
fourth and fifth games, what was her
average number of goals per game?

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

sina-sinb

cosb+cosa

tana-tanb

cos0+cos x pi/3
