First find their rates...
1/6, 1/2, and 1/3 now combined they will perform the job in one day if:
t/6+t/2+t/3=1 make all have a common denominator
t/6+3t/6+2t/6=6/6 which is equal to:
6t=6 so
t=1
So if they all work together they will complete the job in one day.
Answer:
Step-by-step explanation:
6x - 9y = 12
subtract 6x from both sides
-9y = 12 - 6x
divide both sides by -9
y = -4/3 + 2/3x
or
y = 2/3x - 4/3
There are fewer people on the bus.
The start of it had at least 5
The end of it had at least 1
What is the image, i can’t see it?
Answer:
D
Step-by-step explanation:
The range of a graph is the span of y-values it covers.
From the graph, we can see that the span of y-values covered goes from y=-3 all the way to y=3.
However, note that at y=-3, while it is a closed circle, it is an open circle at y=3.
This means that we do <em>not</em> include y=3 in our range, but we <em>do</em> include y=-3 in our range.
So, our range is all values between -3 and 3 including -3.
In set notation, this is (and remember since this is the range, to use y):

So, our answer is D.
And we're done!
