Use algebraic rules of equations to predict the solution type to the system of equations. Include all of your work for full cred
Tasya [4]

y=-4-x

y=2x-1


-4-x=2x-1

3x=-3

x=-1

y=-3


The type of equation is consistent because they intersect at ( -1,-3 )

The terms -12x^2y and 4x^2y can be added to 3x^2y to result in a monomial.

Step-by-step explanation:

Given term is;

3x^2y

A monomial is an algebraic expression that consists of only one term.

So in the given expressions, we will add the terms which have same variables as given terms.

Given options are;

3xy\\-12x^2y\\2x^2y^2\\7xy^2\\-10x^2\\4x^2y\\3x^3

The terms -12x^2y and 4x^2y can be added to 3x^2y to result in a monomial.

Me need help pweaseee can anyone help
Kryger [21]

Answer:

B

Step-by-step explanation:

A 90 degree rotation would be a rotation of 90° about the origin. Knowing this, we can eliminate C since it is a 180° rotation. We can also eliminate A, as it would be a 0° or 360° rotation. This leaves us with B and C.

A counterclockwise rotation would be one that goes the opposite direction of the rotation of the hands of a clock. A 90° counterclockwise rotation would yield triangle B, making that our answer.

I hope you find my answer and explanation to be helpful. Happy studying.
