Which of the following is(are)the solution(s) to |x+3|=12?

1 answer:

3 0

For the equation, we only know that x+3= 12 or x+3 = -12.

(X+3=12) First possible solution.
X +3 = 12
Add -3 to each side which will get rid of 3 and leave X= 12-3
Which leads to X= 9.
(X+3= -12) Second possible solution.
X+3= -12
Add -3 to both sides which will get rid of 3 and leave x= -12 -3
Which leads to x= -15

Answer: x= 9 or x= -15

Is y=10.2x a proportional relationship?

BabaBlast [244]

Answer:

Step-by-step explanation:

Yes!

The condition needed to get a proportional answer is the y intercept must be 0. No other value can be added on. It doesn't matter that the constant of proportionality is not an integer. x and y will always differ by 10.2 as a multiplied value

Put another way, the fraction y/x will always give 10.2
