Jan needs to buy a backpack and several folders for school. If she shops at Smart Supply,
the backpack will cost $45 and folders cost $0.45
each. If she shops at The Supply Guys, the
backpack will cost $50.40 and folders will cost
$0.15 each. Write the inequality to find the
number of folders Jan Would need to buy from
The Supply Guys to be the cheaper option.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

27 +27 or 27times 2=54

the diffrence is 0
