(car sales) of the cars sold during the month of july, 87 had air conditioning, 99 had automatic transmission, and 66 had power steering. 7 cars had all three of these extras. 17 cars had none of these extras. 22 cars had only air conditioning, 64 cars had only automatic transmissions, and 27 cars had only power steering. 8 cars had both automatic transmission and power steering. how many cars had air conditioning and automatic transmission but not power steering?

  27

Step-by-step explanation:

You are given that 99 have an automatic transmission. Of those, 64 had only automatic transmission, and 8 had both automatic transmission and power steering. Then the number that have automatic transmission and air conditioning, but not power steering is ...

  99 -64 -8 = 27

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
