Put the second equation so it's in y= form, it should be the same :)
Answer:2.4
Step-by-step explanation:
12 * 20% = 12 * 0.20 = 2.4 hours
It will not last the entire shift.
Distribute the 3 to 4m and 6. this makes 12m-18=12
now add 18 to both sides.
12m=30
now divide by 12
m=30/12
The answer is 19.. substitute -1 into the function whenever you see x put -1 there. This implies that 3+16 =19
