kolbaska11 [484]

Answer:

$x = \frac{1}{32} \\$

Step-by-step explanation:

${2x}^{(2 - 3)} = 64 \\ {2x}^{ - 1} = 64 \\ \frac{2}{x} = 64 \\ x \times \frac{2}{x} = 64 \times x \\ 2 = 64x \\ \frac{2}{64} = \frac{64x}{64} \\ \frac{1}{32} = x \\$

what are the new coordinates for (1,4) when rotated 180 degrees and 90 degrees counterclockwise, and 90 degrees clockwise?

Lady bird [3.3K]

90 degrees counterclockwise and 90 degrees cancel each other out. The coordinates of the point are only reflected over the x-axis. The point becomes (1, -4).

Hope I helped :)
