The wall of a shower in a bathroom is 2 m high and 1.5 m wide. a (a) What is the area of the wall, in m²?? (b) What is the area of the wall, in cm²?? (c) The bathroom tiles are square, with a side length of 15cm. What is the area of a tile, in cm²?? (d) How many tiles would be needed to tile the shower wall? . (e) What would be the cost of tiling the wall, if the price of one tile is $3.15?

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

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
