If two quantities are equal to the same quantity, then they are to each other: if a = b and b = c, then

ANSWER:

If two quantities are equal to the same quantity, then they are equal to each other: if a = b and b = c, then a = c

SOLUTION:

Given that, two quantities are equal two to the same quantity.

Suppose the two quantities be x and y  

Now, imagine that, both x and y are equal to a third quantity.

Let the third quantity be z.

Then, according to our assumption x = z and y = z  

Then, we can write it as x = and z and z = y ⇒ x = y  

Which means the first two quantities are equal.

Now, we are also given that, a = b and b = c, then just like above assumption, here a equals to c i.e. a = c

Hence, If two quantities are equal to the same quantity, then they are equal to each other: if a = b and b = c, then a = c

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
