Answer:
-5
Step-by-step explanation:
4+2(x-4) = -7(x+7)
First, work out parenthesis: 4+ 2x-8 = -7x -49
Combine like terms: 2x-4= -7x-49
now isolate x by first adding 49 to each side: 2x+45= -7x
Then subtract 2x from each side: 45= -9x
Last, divide both sides by -9:
x= -5
Answer:
Step-by-step explanation:
We will put the number of wanted outcomes over the number of possible outcomes.
Answer:
the y-intercept is 2.
Step-by-step explanation:
If you find the rate of change, which in this case is 1/-4, you can reverse the rate of change.
1 and -2
-1 (instead of adding 1) to x
+4 (instead of subtracting) to y
you get (0, 2).
Making the y-intercept 2.
