Un<br> How many solutions does this system have?<br> 12x-4y=-8<br> y=3x+2
Talja [164]

Answer:

Infinite

Step-by-step explanation:

Get both in the form y = first.

12x - 4y = -8

-4y = -8 - 12x

y = 2 + 3x

y = 3x + 2

These are the same line so all points are the same so that means there are infinite answers.

If ONLY the number in front of the x was the same there would be 0 answers, they would be parallel lines, and if the number in front of the xs were different there would only be one answer.

Can you please help me and explain this in a way that I can understand ​
melomori [17]

Answer:

180 Degrees

Step-by-step explanation:

So, m∠1 = m∠2 = m∠3 means that these angles are the same degrees

The question asks whats the degree of m∠CDG so first we find those points. In this image, it looks like points C,D and G form a line which is also equivalant to 180.

I hope you understand! If not, i'll try to elaborate more
