Answer:

Add 9 to each side of the equation.

Step-by-step explanation:

To complete the square, we need to add (b/2) ^2 to each side, where b is the coefficient of the x terms.

The coefficient of the x terms is -6

so we need to add (-6/2) ^2 = (-3)^2 = 9.

Add 9 to each side of the equation.

Solve the system of inequalities to decide if the point (-3,2) is part of the solution; y<=-4x-3, +8y>=7

inna [77]

Answer:

$(x,y) = (-3,2)$ is a solution

Step-by-step explanation:

Given

$y \le -4x + 3$

$x + 8y \ge 7$

Required

Determine if $(x,y) = (-3,2)$ is a solution

$y \le -4x + 3$ becomes

$2 \le -4 * -3 + 3$

$2 \le 15$ --- this is true

$x + 8y \ge 7$

$-3+ 8 * 2 \ge 7$

$13 \ge 7$ --- this is also true

Hence,

$(x,y) = (-3,2)$ is a solution
