Solve the following system of equations
1.2x+2.4y= -18
-.8x+ .4y = 6

HELP I need the answer RIGHT NOW ASAP (I spaced it out so you could see it better)

x = -9

y = -3

Step-by-step explanation:

We can first multiply the 2nd equation by -6, so we have:

Now, we add up this equation to the 1st equation given to eliminate y and solve for x. Shown below:

So, we have the value of x to be -9

Now, we substitute this value in 1st equation and solve for y:

The value of y is -3

So,

x = -9

y = -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

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.
