Domain: Every possible x value.
Range: Every possible y value.
Answer:
Domain: [-5,-3)⋃(-2,4]
Range: [-1,4]
Remember that when there is unfilled dot on the graph that means whatever the number is there on x and y isn't being used which you can follow it by ) not ]. Although Y=2 isn't used on the right function but there is value for Y on the left one which is equal to X=-4 and the same goes for Y=3. On the other hand when it comes for the X=-3, that's not a part of the domain neither the X=-2.
Since the slope is 2/3, for every time the x-value increases by 1
the y-value increases by 2/3.
The answer to x is found by finding the difference between 3 and 5, which is 2.
2/3 goes into that 3 times.
So subtract 2 from -2 to get -4.
The x-value is -4.
The answer for the y-value is given earlier:
the original point of (-2,5).
The y-value is 5.
Hope this helps!
You can not "solve" this, so to speak, rather simplify this expression. Take the "2" and multiply that by the "a" and the "3" in the parentheses. You will then have the simplified answer of: 2a times 6.
Hope that helps!
You can use rounding to figure this problem out. If the number in the ones place is 0 to 4, round down to the nearest tens place; if the number in the ones place in 5 to 9, round up to the nearest tens place.
48 rounds to 50.
42 rounds to 40.
69 rounds to 70.
21 rounds to 20.
52 rounds to 50.
Now use mental math to estimate the cost (50 + 40 + 70 + 20 + 50). Heather will spend about $230.
Answer:
D) $230
