8. How many solutions does this system have?
y = x-3
4x - 10y=6
9. How many solutions does this system have?
x + 3y = 0
12y = - 4x
10. What can you determine about the solution(s) of
this system?
-64x + 96y = 176
56x -- 84y = -147
(11. Determine whether this system of equations
has one solution, no solution, or infinitely many
solutions.
y=8x + 2
y = -8x + 2
12. Construct Arguments Maia says that the two lines in this system of
linear equations are parallel. Is she correct? Explain.
2x + y = 14
2y + 4x = 14
13. Reasoning Describe a situation that can be represented by using this system of
equations. Inspect the system to determine the number of solutions and interpret
the solution within the context of your situation.
y=2x + 10
y=x+ 15

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

2 x t divided by n

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
