Mathematics

Answer:

x = √(-1) = i

Since the value of √(-1) is not real.

The system has no real solution.

Step-by-step explanation:

The solution to the system of equations is at the point where they intercept each other.

y1 = y2

For the given equation;

y=x^2-2x and y=-2x-1

To get the where they intercept, we will equal both equations;

y=x^2-2x = -2x-1

x^2 - 2x = -2x - 1

x^2 - 2x + 2x + 1 =0

x^2 +1 = 0

x^2 = -1

x = √(-1) = i

Since the value of √(-1) is not real.

The system has no real solution.

How can you show two figures are congruent?
galina1969 [7]

If at least two sides and one angle of two triangles are similar, then the triangles are congruent.

What in mathematics is the congruent?

  • It is claimed that two figures are "congruent" if they can be positioned exactly over one another.
  • Both the shape and size of the bread slices are same if you lay one slice on top of the other.
  • Congruent refers to having precisely the same form and size.

Use the Third Angles Theorem for  two figures are congruent.

When two of a triangle's angles match up with two of another triangle's angles, the third angle must likewise match up.

If at least two sides and one angle of two triangles are similar, then the triangles are congruent.

I need some assistance on this
Elena L [17]

Answer:

1650

Step-by-step explanation:

The shape is a pyramid on top of a prism.

Volume of a pyramid is V = ⅓ Ah, where A is the area of the base and h is the height of the pyramid.

Volume of a prism is V = Ah, where A is the area of the base and h is the height of the prism.

The base of both shapes is a right triangle.  The area is:

A = ½ bh

A = ½ (22) (10)

A = 110

The height of the prism is 6.  The height of the pyramid is 33 − 6 = 27.  The total volume is:

V = (110) (6) + ⅓ (110) (27)

V = 1650
