X + 2y = 10 . . . (1)
6y = -3x + 30 . . . (2)
From (2), 3x + 6y = 30
3(x + 2y = 10)
3 x (1)
Since, the second equation is a multiple of the first equation, the system will have an infinitely number of solutions.
288 divided by 12 = 24
240 divided by 10 = 24
Answer: C
Step-by-step explanation:
Answer:
-8
Step-by-step explanation:
First we need to find the slope of CD.
We know C is (-10, -2)
and we know D is (10,6)
If we use the slope formula, we can see the slope is 

We can see point F is at (6,-4)
We can find the equation of this line by using point slope form, and plugging in F as our point.

To find where E, we need to find the y value when x = -4
