Answer from: PatienceJoy

After the two weekends she made $997

Step-by-step explanation:

* Lets explain how to solve the problem

- The profit is the difference between the selling price and the

cost price

- On the weekends, Ms. James had a booth where she sold books

- First weekend she made a profit of $1275

- Next weekend, when she subtracted the costs of the booth,

Ms.James lost $278

- That means the cost price is greater than the selling price

- To know how much she made in the two week end you must

subtract the money she lost from her profit

∵ Ms. James made a profit $1275 in the first weekend

∵ She lost $278 in the second weekend

- After the two weekend she made the difference between the

two weekends

∴ She made = 1275 - 278 = 997

∴ After the two weekends she made $997

Answer from: Quest

the system of inequity is

$y\leq -x+4$

$3y> x$

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

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

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

$y-4=\frac{0-4}{4-0}(x-0)$

$y=-x+4$

the related equation of solid line is $y=-x+4$ .

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

$y-0=\frac{0-1}{3-0}(x-0)$

$3y=x$

the related equation of dashed line is $3y=x$

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).

$1=-0+4$

$1=4$

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 $\leq$ . the required inequality is

$y\leq -x+4$

similarly, check the second related equation.

$3(1)=0$

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

$3y> x$

15 points write a system of inequalities to represent the shaded portion of the graph
