So, we’re looking for the amount of money Tom needs to spend to get his free meal.
X + 30.25 >
X > 9.75
X is the additional amount that Tom needs to spend. You subtract 30.25 on both sides in order to solve for x.
So, your answer would be at least $19.75
Answer:
-7
Step-by-step explanation:
2-3(3)=-7
The correct answer would be C
Answer:
A. (x, y) -> (0.2x, 0.2y)
Step-by-step explanation:
I'll test this out with just point S if that's fine.
Point S's coordinates are (5, -5), as seen on the coordinate plane.
However, Point S' has coordinates of (1, -1).
Divide 1 by 5 to get 1/5. You can also do -1/-5 to also get 1/5 (Remember, dividing two negatives gets you a positive.).
So you can conclude that the dilation has the x and y coordinates shrinking to 1/5 of the original. Both coordinates shrink at the same rate, so B and C are out. The figure is NOT getting bigger so D is also incorrect. This leaves A ((x, y) -> (0.2x, 0.2y)) as our answer.
W is in the lower left corner located at (-1,-2)
W' is in the upper left corner located at (-2,1)
Notice that the original Y value (-2) became the new X value (-2) and the original X value (-1) is the inverse of the new Y value (1).
If you look at the coordinates of the other two pints you would see it was the same transformation.
When the X and Y coordinates switch like this, it is a 90 degree clockwise rotation around the origin.
