Classify the sentences based on whether they are or are not statements.

1. You shouldn’t add two numbers before factoring them.

2. The square root of 16 is 4.

3. Two congruent shapes can be mapped onto one another.

4. AA isn’t a criterion for congruence of triangles.

5. The formula for area of a square is easy to remember.

6. A triangle has six medians.

The statements are numbers 1, 3, 4

The non statements are 2, 5, 6

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

it could be 1,3 and more others to create a cylinder.
