The dinosaur's tail bones are at the solution point to the system of equations below. –2x – 7y = –250 4x – y = 140 every time you click a point using the cps, the equations below will update. remember, the solution is the point that makes both equations true. –2( 0 ) – 7( 20 ) = -148 x 4( 0 ) – ( 20 ) = -4 x

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
