Step-by-step explanation:

This story is about Tricki, a dog who is the pet of a rich lady named Mrs. Pumphrey. She loves her dog very much and is unable to refuse him anything he wants. Tricki, is fond of eating cream cakes and chocolates. So one day when Mrs. Pumphrey is out with Tricki for a walk the narrator sees them and stops to talk. While talking to Mrs. Pumphrey he realises that she has been overfeeding Tricki and also had been giving him things that he shouldn’t eat due to which Tricki had started looking like a bloated sausage. Soon Tricki got unwell and Mrs. Pumphrey has to call Mr. Herriot (narrator) for help. She does not want to send him away but the only way suggested by Mr. Herriot is to get him hospitalised for 15 days. Then the story unfolds into how he gets well. Read the description to know more.

I'm pretty sure the answer is the US

I'm so sorry if it's wrong, hope this helps though :)

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
