Answer:

Step-by-step explanation:

${(2x + 3y)}^{2} + {(2x - 3y)}^{2} \\ (2x + 3y)(2x + 3y) + (2x - 3y)(2x - 3y) \\ 2x(2x + 3y) + 3y(2x + 3y) + 2x(2x - 3y) - 3y(2x - 3y) \\ {4x}^{2} + 6xy + 6xy + {9y}^{2} + {4x}^{2} - 6xy - 6xy + {9y}^{2} \\ {4x}^{2} + 12xy + {9y}^{2} + {4x}^{2} - 12xy + {9y}^{2} \\ {4x}^{2} + {9y}^{2} + {4x}^{2} + {9y}^{2} \\ {8x}^{2} + {18y}^{2} \\ 2( {4x}^{2} + {9y}^{2} ) \\ 2( {2}^{2} {x}^{2} + {3}^{2} {y}^{2} ) \\ 2({(2x)}^{2} + {(3y)}^{2}) \\$

given the line 2x - 3y - 5 = 0, find the slope of a line that is perpendicular to this line. 3/2 2/3 -3/2

svp [43]

2x-3y-5=0
2x-5=3y
3y=2x-5
y= $\frac{2}{3} x- \frac{5}{3}$
Gradient of line 1 = $\frac{2}{3}$
Gradient of line 2;
$m_{1} * m_{2} =-1$
$m_{2} * \frac{2}{3} =-1$
$m_{2} =- \frac{3}{2}$

Triangle ABC is shown on the graph below. c. Triangle ABC is translated 1 unit right and 2 units down what are the coordinates o

ruslelena [56]

The translation would be written as (x, y)→(x+1, y-2). A would be mapped to A'(2, 1); B would be mapped to B'(5, 3); and C would be mapped to C'(4, -1).

For each ordered pair, you would add 1 to the x-coordinate and subtract 2 from the y-coordinate.
