Kiara found the solution for the inequality, 3.2 less-than negative 9.5 + x. 3.2 less-than negative 9.5 + x. 3.2 + 9.5 less-than negative 9.5 + 9.5 + x. 12.7 less-than x. A number line going from 12 to 12.9. An open circle is at 12.7. Everything to the left of the circle is shaded. What is Kiara’s error? Kiara should have added 9.5 to each side of the inequality to get the solution 6.3 less-than x. Kiara should have reversed the variable and the number in the solution to get x less-than 12.7. Kiara should have used a closed circle on the graph. Kiara should have shaded the number line to the right of the circle.

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
