3. on day 16, ebony deposited $100 into her account. on each day after day 16, segment 5, ebony made a deposit, and those deposits were equal to each other. (a) explain how you can determine, just by looking at the graph, whether the amounts she deposited after day 16 were each less than $100, $100, or more than $100. (b) use the graph to estimate in hundreds. explain how you determined this estimate. then show how you can estimate the amount of money ebony deposited into her account each day after day 16.

yo answer should be 6 if im not mistaken

step-by-step explanation:

(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
