Answer:

x+y\geqslant 12

x+2y\leqslant 20

Step-by-step explanation:

<u>Inequalities </u>

The home security company will choose between two options for cubicles: the small cubicle for only one operator and the large cubicle to hold 2 operators. Let x be the number of small cubicles and y the number of large cubicles. Since each small cubicle has 49 square feet, the total area occupied by them will be 49x. Each large cubicle occupies 80 square feet, so the y cubicles use 80y square feet. The total area used by them is

Area=49x+80y

Assuming there is no operator without cubicle and all cubicles are fully occupied, the number of operators will be

Operators=1x+2y=x+2y

The number of cubicles is

# cubicles=x+y

The conditions of the problem state that

x+y\geqslant 12

x+2y\leqslant 20

The graph of a line is shown below. What is the equation of the line, in slope-intercept form, that is parallel to this line and
dimulka [17.4K]

Answer:

y =  -  \frac{3}{2} x + 1

Step-by-step explanation:

Slope -intercept form: y= mx +c, where m is the slope and c is the y-intercept.

Parallel lines have the same slope. Let's find the slope of the given line.

Given points: (-2, 0) and (0, -3)

\boxed{slope =  \frac{y1 - y2}{x1 - x2} }

slope of given line

=  \frac{0 - ( - 3)}{ - 2 - 0}

=  \frac{0 + 3}{ - 2}

=   - \frac{3}{2}

y =  -  \frac{3}{2} x + c

Given that the y- intercept is 1, c= 1.

y =  -  \frac{3}{2} x + 1
