It may be 1^4 ............................
Can be expressed as y=0.55n
The answer is 7 because 2 to 5 is 3 and -2 to 5 I 7
Step-by-step explanation:
You're asking why

let's transpose the first equation for y
-2x-6y=18
-6y=18+2x
6y=-18-2x
y=-18/6-2x/6
y=-3-⅓x as required
Anything greater than 4 but less than 9
