Answer: B
Picture 1 shows the reflection of ABC 180° clockwise about the origin. To draw A'B'C' we draw the line segments AO, BO, and CO and extend them such that O is the midpoint of line segments AA', BB', and CC' respectively.
Picture 2 shows the line y=-x (the yellow line.) This is the line containing all points of the form (x, -x), that is, this points contains (1, -1), (-2, 2) etc...
We see that point C' is already on this line, and we draw the reflections of points B and C with respect to this line, to find B'' and C'' with coordinates as shown in the figure.
Answer:
(f-g)(x)=7
Step-by-step explanation:
f(x)=2x
g(x)=2x-7
(f-g)(x)=f(x)-g(x)=2x-(2x-7)=7
Answer:
244
Step-by-step explanation:
I assume this asks 90+90+64 = ?
So, you can put it all in a calculator and get 244
If you have any questions or I have interpretated the question wrong, feel free to comment! :D
We add 25/8 yards and 1 3/4 yards together.
First we convert 1 3/4 to an imp. fraction 7/4.
In order to add fractions, they must have the same common denominator. So we multiply both sides of the fraction 7/4 by 2 to get 14/8. Now we can add 25/8 yards and 14/8 yards together to get 39/8 yards.
