Solve the system by substitution. please help this is due tomorrow 7. y = x - 4
y = 4x - 10

the solution is (2, -2)

Step-by-step explanation:

We'll solve this system by substitution.  Set y = x - 4 = to y = 4x - 10.  The result, which no longer features y, is x - 4 = 4x - 10.  

First, subtract x from both sides.  We get -4 = 3x - 10, or 6 = 3x.  Then x = 2.

Substituting 2 for x in y = x - 4, we get y = 2 - 4, or y = -2.

Then the solution is (2, -2).

y=-2

x=2

Step-by-step explanation:

If y=x-4, that means x is 4 larger than y.

y=4x-10

If y is 2 and x is 6 (2≠24-10) or (2≠14)

If y is 1 and x is 5 (1≠20-10) or (1≠10)

If y is 0 and x is 4 (0≠16-10) or (0≠6)

The pattern is that each time y and x goes 1 down, the difference between y and x goes down 3 each time. So if you keep on going down in the negatives,

If y is -2 and x is 2 (-2=8-10) or (-2=-2)

I would appreciate it if you pick this answer (It'll be my first one)

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
