Question 2:1 pts Frank and Angio are making pizzes for their business. If Frank can produce all of the nocesoary pizzas on his own in 8 hours and Angie can do tho same job in 4 hours, then what portion of the day's pizzas can they make together in 1 hour? O 1 10 O la ww O 12 Question 4:1 Kim and her little brother are picking strawberries. Actually, Kim picks the strawberries and her brother eats them out of the pail. If Kim could fill the pail in 16 minutes without her brother's intervention, and he can eat all the berries in 32 minutes, how long does it take Kim to fill the pail? O 20 min None of these 32 min 24 min 48 min Question

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
