1 way (without equation)
Kathy counts in total 9 goats and sheep at the petting zoo. Her brother counts 4 goats. Then if you subtract the amount of goats from the total amount, then you obtain the amount of sheep.
9-4=5 is the number of sheep at the petting zoo.
2 way (with equation)
Let x be the number of sheep at the petting zoo. If brother counts 4 goats, then the total number of animals is x+4. Kathy counts in total 9 goats and sheep at the petting zoo, then x+4=9.
Solve this equation:
x+4-4=9-4,
x=5.
3 way (with equation)
Let x be the number of sheep at the petting zoo. If total number of animals is 9, then the amount of goats can be found as 9-x. Brother counts 4 goats, then
9-x=4,
9-4=x,
x=5.
5 sheep.

C. a reflection across the x-axis, and then a dilation by a scale factor of 2
Step-by-step explanation:
We see that the shapes are on the opposite sides of the x-axis, and vertical lines are still vertical. A 90° rotation would have made the vertical lines horizontal.
We see that the line that was 1 unit long is now 2 units. The line that went from 4 to 6 goes from 8 to 12. This is evidence of a dilation bt a factor of 2.
