A teacher asks her students to design a game board for a class project. The dimensions of the boards created by four students are shown below. Angela length: 20 cm width: 21 cm diagonal: 29 cm Bradley length: 9 in. width: 9 in. diagonal: 9 in. Carlton length: 25 cm width: 30 cm diagonal: 35 cm Della length: 10 in. width: 12 in. diagonal: 15 in. Whose game board could be a rectangle? Angela Bradley Carlton Della

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

i believe b is the answer

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
