Answer:
x = 
, y = -1.71
Step-by-step explanation:
sub y = x+4 in the first equation to get:
12 x - 5 (x+4) = -20
Simplify:
12 x - 5 x + 20 = -20
Further simplify:
7 x = - 40
Divie both sides by 7 to get:
x =
--> x = -5.7
Sub x = in the second equation to get:
y = + 4 = -1.71

If x is the first number in the sequence, you can represent the next consecutive number using (x+1), the one after with (x+2), etc. We can set up an equation like this:
x + (x+1) + (x+2) + (x+3) = 130
This can be simplified to:
4x + 6 = 130
Now subtract 6 from each side:
4x = 124
Next we divide each side by 4:
x = 31
We have the first number in the sequence, but we need the THIRD number. Since we've already established that (x+2) would be the third number, we can just plug in x.
31 + 2 = 33
The third number in this sequence is 33.

is the answer thanks
give me the brainliest pls
Slope equals the change in y over change in x, or rise over run.
-4-3 / -6-2
-7/-8
7/8
Final answer: 7/8
