Answer:
it's d
Step-by-step explanation:
the domain can't repeat for it to be a function and it repeats in d. Which means it isn't a function.
The correct answer is 1. k = 22.5<span>
2. xy=k</span>
Answer: 1+1=2 so if that is right we take the same principle. 2+2=5 BOOM
Step-by-step explanation:
Answer:
T' (4,8)
S' (4,-4)
R' (-4,-4)
U' (-4,8)
Step-by-step explanation:
A dilation is an enlargement if the scale factor is greater than 1 and a reduction if it is less than 1. In this it is an enlargement so you multiply each coordinate by the scale factor which is 4. Since the coordinate for T is (1,2) you multiply 1x4 and 2x4 making the new coordinate (4,8). Since it is a new coordinate you add ' to the letter for the coordinate. Then you do that for the rest of the coordinates and graph it.
Answer:
C.
Step-by-step explanation:
In order to find when the other car catches up to the other, you need to graph the distance and time for both cars. The linear function will represent their rate of speed, when the lines intersect, that is when car 2 catches up to car 1.
Hope this helps.
