In 1990, 53.4% of commuters took public transportation in New York City, which was 19.9% greater than the percentage in San Francisco. Write and solve an equation to find what percentage of commuters p took public transportation in San Francisco.
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
