The first answer is correct
Answer:
-0.8 or -4/5
Step-by-step explanation:
You could do this a couple of ways. If you wanted to change your equation into slope-intercept form to make it easier for you, then you can do as follows:
4x + 5y = 10
5y = -4x + 10
y = -4/5x + 2
So your slope is -4/5.
Or you could do -A/B when your equation is in standard form. A is the term in front of the x value and B is the term in front of the y. Both strategies give you -4/5 for the slope.
When 3g+6(-g+(-5)) is broken down, it makes -3g+-5
So, Katherine can do 0.1 of the job per hour. (if she needs 10 hours for the job, each hour she can do the whole divided by the time, so 1/10, which is 0.1)
if in two hours she and Marina can be done, then Marina will do 1(the whole job)-2/10 (twice as much as she can do in an hour)=0.8 of the job. So if Marina does 0.8 of the job in two hours, each hour she will do half of it: 0.4 - and this is the correct answer
