Answer: D
Step-by-step explanation:
We know that the line is shaded below, so it represents .
Similarly, the line is shaded above, so it represents .
Answer:
B. Quadrant 1
Step-by-step explanation:
Dilation about the origin multiplies each coordinate by the dilation factor. If the dilation factor is positive, the signs of the coordinates are unchanged, so the point they specify remains in the same quadrant.
If the dilation factor is negative, the point is reflected across the origin at the same time it is subject to dilation. That is, both coordinate signs are changed.
For a dilation factor of -2, the point L becomes ...
L(-2, -3) ⇒ L' = -2L = L'(4, 6) . . . . . in quadrant I
Answer:
It is most probably 160 cause' it is given in the scale that 1 cm=40 km<em>.</em><em> </em>So as of my view<em>,</em><em> </em><em>there</em><em> </em><em>is</em><em> </em><em>4</em><em> </em><em>cm</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>distance</em><em> </em><em>marked</em><em>.</em><em> </em><em>So</em><em> </em><em>it</em><em> </em><em>will</em><em> </em><em>be</em><em> </em><em>4</em><em>0</em><em>*</em><em>4</em><em> </em><em>cm</em><em>=</em><em>1</em><em>6</em><em>0</em><em> </em><em>cm</em><em>.</em>
60% of 120 is 72. Therefore, Mark has only saved 72 dollars.
