Round 9.35550 and 7.57530 to: 5 digits 4 digits 3 digits 2 digits

a) 9.35550

5 digits: 9.35550

4 digits: 9.3555

3 digits: 9.356

2 digits: 9.36

b) 7.57530

5 digits: 7.57530

4 digits: 7.5753

3 digits: 7.575

2 digits: 7.56

Step-by-step explanation:

for rounding if the last digit is less than 5 then the last digit remains same, but if the last digit is 5 or greater than 5 then the last digit is increased by 1 or rounded off to next digit.

(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

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
