How many solutions does this system of equations have? y = 4x - 4 y = -4x + 4

Step-by-step explanation:

y = 4x - 4 slope here is 4 and y int is -4

y = -4x + 4...slope here is -4 and y int is 4

now we compare our slopes and y int's

learn these, it helps...

if the slopes are different, and y int's are different, then u have 1 solution.

if the slopes are the same and the y int's different, then u have no solutions

if the slopes are the same and the y int's the same, there are infinite solutions.

so ur answer is : 1 solution

step-by-step explanation:

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
