Asnowmobile manufacturer claims that its newest model is 15% lighter than last year's model. if this year's model weighs 799 lb, how much did last year's model weigh?

The weight of last year's model was 940 pounds

Step-by-step explanation:

Remember that

Let

x ----> last year's model weigh in pounds

we know that

Last year's model weight multiplied by 0.85 must be equal to the weight of the newest year's model

so

The linear equation that represent this situation is

solve for x

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

4x and 6y

im not sure though
