Answer:
C. Yes, ΔRST can be reflected across the line containing RT and then rotated about T so that S is mapped to Y.
Step-by-step explanation:
Rigid transformations are processes that can be applied to change the orientation or size of a given object, while its shape is maintained. Examples are; rotation, reflection, dilation and translation.
To map ΔRST to ΔXYT, the rigid transformations required are; reflection and rotation. ΔRST can be reflected across the line containing RT and then rotated about T so that S is mapped to Y.
Therefore, option C is correct from the given question.
Answer:
x ∈ All real numbers
Step-by-step explanation:
When the distributive property is applied to the left side, the parentheses can be eliminated and the equation becomes ...
-2x -6 = -2x -6
This is true for all possible values of x, "all real numbers".
Answer:
3
Step-by-step explanation:
Reduce the expression using the order of operations
-- To change a percent into a decimal, move
the decimal point two places this way <== .
33.3% = 0.333 .
-- To change a percent into a fraction, remember
that the symbol ' % ' means ' /100 ' .
33.3 % = 33.3/100 .
That fraction looks ugly, because it has a decimal in the numerator.
That's easy to fix. Multiply top and bottom by 10, and you have
333/1000 .
The answer is A. It is less than or equal to because the line is solid instead of dashed. It is less than because the shaded portion is below the line.
