An office building has 23 offices. the floor area of each office is 305  square feet. which shows the equation you can use to find the floor area, n n , of all the offices and the value of n n ? a. 23 + 305 = n , n = 810 square feet 23+305=n, n= 810 square feet b. 23 × 305 = n , n = 1 , 405 square feet 23×305=n, n=1,405 square feet c. 23 × 305 = n , n = 1 , 425 square feet 23×305=n, n=1,425 square feet d. 23 × 305 = n , n = 7 , 015 square feet 23×305=n, n= 7,015 square feet

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be

ou would have 12 of each
