Answer : rotation of 90 counterclockwise° about the origin and then translation 2 unit up.
Explanation : In Δ RST, it is an right triangle with ∠R being the right angle. When we draw this triangle we see that long side of the Δ is close to the origin and the short one is below ∠R.
Now, Δ R'S'T', is also a right triangle. But he long side is parallel to the y axis and ∠S' is now above ∠R' instead of ∠S being to right of ∠R in the original Δ.
which clearly shows that the Δ is rotated at 90 degrees counter clockwise.
On drawing a new Δ; The point R" is at (1,-4), S" at (1,-1), and T" at (2,-4).
All three of these points are 2 units below the points R' S' T'.
We need to translate the triangle 2 units higher.
Therefore, the answer is to perform rotation of 90 counterclockwise° about the origin and then translation 2 unit up.
Answer:
4
Step-by-step explanation: because you up four and move 1 so the answer is 4/1 but is simplified by 4
Answer:
Discount of $12.50.
Sale price is $37.50.
Step-by-step explanation:
Since the dress is "Marked save 25%" this means yuo pay 75% of the $50 price. Remember, 100-25 = 75. This means you pay 0.75*50 = $37.50 and yuo got a discount of $12.50.
$50 - 37.50 = 12.50
Answer:
4x - y = -5
Step-by-step explanation:
The equation of a new line which is parallel to old line 4x - y = 14 looks exactly the same as that of the old line EXCEPT that we replace the constant, 14, with C and find C for the line that passes through (-2, -3).
4x - y = 14 becomes 4x - y = C
Now substitutte -2 for x, -3 for y and calculate C:
4(-2) - (-3) = C, or
-8 + 3 = C = - 5
Thus, the new equation is 4x - y = -5
