The three tools the federal reserve uses to enact monetary policy are: a.) determine whom banks loan money to b.)setting the reserve rare c.)setting the interest rate changed to commercial banks on loans from federal reserve d.)the buying and selling of treasury bonds and other goverment-backed securities

Option:

B , C and D are the correct options.

Step-by-step explanation:

The goals of monetary policy are:

B.)setting the reserve rate.

C.)setting the interest rate changed to commercial banks on loans from federal reserve. 

D.)The buying and selling of treasury bonds and other government-backed securities.

(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
