Matt is climbing a mountain. when his elevation is higher than 16001600 meters, breathing is difficult for matt. write an inequality that describes hh, the elevation at which breathing is difficult for matt.

Step-by-step explanation:

We have been given that Matt is climbing a mountain. When his elevation is higher than 1600 meters, breathing is difficult for Matt.

We are asked to write an inequality that describes h, the elevation at which breathing is difficult for Matt.

We know when elevation (h) will be higher than 1600 meters Matt will face difficulty in breathing. We can represent this situation as:

Therefore, inequality representing the elevation at which breathing is difficult for Matt will be .

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

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
