Johanna had school loans that totaled $70,792. she paid off $ 46,375 of her loans. she estimates that she has about $25,000 left to pay. which of the following explains how johanna could have figured this out?

a) johanna rounded 70,792 and 46,375 to the nearest thousand and then subtracted the rounded numbers.

b) johanna rounded 70,792 and 46,375 to the nearest ten thousand and then subtracted the rounded numbers.

c) johanna rounded 70,793 and 46,375 to the nearest hundred and then subtracted the rounded numbers.

d) johanna subtracted 46,375 from 70,792 and then rounded the difference to the nearest hundred.

(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
