The length of AD is 75. Since opposite sides have the same length, 63 plus 63 is 126. The perimeter is 276, so 276 minus 126 is 150. 150 divided by 2 is 75.

Which of the following equations has the same solutions as the equation 3x+2y=-12? Check all that apply.

grigory [225]

ANSWER

$B,C,E \: and \: F$

EXPLANATION

The given equation is
$3x + 2y = - 12$

The solution to this equation can be found by making y the subject.

$\Rightarrow \: 2y = - 3x - 12$

$\Rightarrow \: y = - \frac{3}{2} x - 6$
This equation has infinitely many solution. Any real value we choose for x, there is a corresponding y-value.

To find which of the given options also has the same solution, we make y the subject.

A

$3x - 2y = 12$

$\Rightarrow \: - 2y = - 3x + 12$

$\Rightarrow \: y = \frac{3}{2} x - 6$

This is not the same as the given equation.

B

$- 3x - 2y = 12$

$\Rightarrow \: - 2y = 3x + 12$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

This solution is the same as the one given.

C.
$15x + 10y = - 60$

$\Rightarrow \: 10y = - 15x - 60$

$\Rightarrow \: y = - \frac{15}{10} x - \frac{60}{10}$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

This is the same as the above solution.

D.
$6x + 2y = - 12$

$\Rightarrow \: 2y = - 6x - 12$

$\Rightarrow \: y = - 3 x - 6$

This is not the same as the one given.

E.

$6x + 4y = - 24$

$\Rightarrow \: 4y = - 6x - 24$

$\Rightarrow \: y = - \frac{6}{4} x - \frac{24}{4}$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

This is the same as the one given.

F.

$1.5x + y = - 6$

$\Rightarrow \: y = - 1.5x - 6$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

Thus is the same as the one given.

G.
$x + \frac{2}{3} y = - 12$

$\Rightarrow \: \frac{2}{3} y = - x - 12$

$\Rightarrow \: y = - \frac{3}{2} x - 12 \times \frac{3}{2}$

$\Rightarrow \: y = - \frac{3}{2} x - 18$

This is not the same as the one given.
