Answer:
y = 9
Step-by-step explanation:
We notice that both points have a y-coordinate of 9. Since they are the same, the equation must be y = 9 because the function can't "dip" or "rise", otherwise it would be a piecewise function and not a linear function. The equation y = 9 basically means that no matter what x is, y will always be 9.
Answer:
x=-3
Step-by-step explanation:
Not sure if this is correct or not but my answer is 48
These were my steps:
2(6+(12divided(3+1)-1
2x6=12. 3+1=4 4-1=3
12divided by 3 =4
So now all we have are 12 from (6x2) and 4 from 12div. By3
Then we multiply 12 with the 4 which =48
Hope that helped and made sense.
