Three vertices of a square have coordinates (5, 1), (2, -2), and (-1, 1). What are the coordinates of the fourth vertex?
Tresset [83]
Plot the points
we notice that the square is tilted diagnaol

remember that the legnths of the diagonals of a square are equal


therefor the distance between the points (5,1) and (-1,1) is the same as the ohter diagonal (distance is 6)

the other point is probably that disance up or the y vairable
(2,-2)+6 on the y
-2+6=4

4/3y=48<br><br>solve for y<br><br>simplify answer as much as posible
Helga [31]
<h2>If you mean :</h2>

\frac{4}{3y}  = 48 \\

Inverse both sides

\frac{3y}{4}  =  \frac{1}{48}  \\

Multiply both sides by 4

4 \times  \frac{3y}{4}  = 4 \times  \frac{1}{48}  \\

3y =  \frac{4}{48}  \\

3y =  \frac{4 \times 1}{4 \times 12}  \\

3y =  \frac{1}{12}  \\

Divide both sides by 3

3y \div 3 =  \frac{1}{12}  \div 3 \\

y =  \frac{1}{12}  \times  \frac{1}{3}  \\

y =  \frac{1}{36}  \\

_____________________________________________

<h2>If u mean : </h2>

\frac{4}{3} y = 48 \\

Multiply both sides by the 3

3 \times \frac{4}{3} y = 3 \times 48 \\

4y = 3 \times 48

Divide both sides by 4

4y  \div 4 = 3 \times 48 \div 4

y =  \frac{48 \times 3}{4}  \\

y =  \frac{4 \times 12 \times 3}{4 \times 1}  \\

y = 12 \times 3

y = 36
