How many solutions does this system have

A) exactly one solution

Step-by-step explanation:

if we set the y values equal we would get

-2x-4 = 3x+3

-7= 5x

x=-7/5

Since we get an x value, the answer is that they have exactly one solution.

i got 10.28 but that rounds up to 10.3

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
