For each figure, which placement of the axes shown would be the best to prove properties about the object?

In a two-dimensional coordinate system, a horizontal axis is known as  the x-axis and the vertical axis is known as the y-axis.

Answers:

Only 3 placements are clear in the attached image.

Circle: The first placement or the left  hand side placement. The center of the circle passes through axis.

Equilateral Triangle: The third or the right hand side placement.

Isosceles Triangle: The second or the middle  placement is the right one.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

their are no angles. sorry cant .
