Atreasure map says that a treasure is buried so that it partitions the distance between a rock and a tree in a 5: 9 ratio. marina traced the map onto a coordinate plane to find the exact location of the treasure. what are the coordinates of the treasure? if necessary, round the coordinates to the nearest tenth. a. (11.4, 14.2) b. (7.6, 8.8) c. (5.7, 7.5) d. (10.2, 12.6)

I think that the answer is C but I am not 100% sure

Step-by-step explanation:

B: (7.6, 8.8)

(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
