Answer:
-6/7.
Step-by-step explanation:
-1/2 w -3/5 = 1/5w
-1/2 w - 1/5 w = 3/5
Multiply through by 10:
-5w - 2w = 6
-7w = 6
w = -6/7.
1, 000 grams = 1 kg
(divide both sides by 1, 000)
1 gram = 1/1, 000 kg
750 grams = 750 x (1/1000) kg = 0.75 kg
Therefore, Steven needs to buy 0.75 kg of sugar!
hope this helps! let me know if you need help with anything else! :)

Answer:
domain: (-4, -2) ∪ [-1, 4]
range: (-5, 3)
Step-by-step explanation:
<u>Domain</u>
The domain is the horizontal extent of the graph. Here, it is comprised of two intervals. The left interval is open, as the function is not defined for x-values of -4 or -2. That interval is (-4, -2). The right interval is closed, as the function is defined for both x=-1 and x=4. That interval is [-1, 4]. The domain is the union of these two intervals.
D: (-4, -2) ∪ [-1, 4]
__
<u>Range</u>
The range is the vertical extent of the graph. The left portion of the graph has a range from -5 to 3, but neither of those values is included in it. That is, the range is an open interval: (-5, 3).
The right portion of the graph has a range from 1 to 2, including both of those values. This interval is already included in the interval (-5, 3), so only one interval is needed to describe the range:
R: (-5, 3)
Answer:
= −10f − 4
Step-by-step explanation:
The answer is B.
You can't multiply, divide, or subtract because it says find the sum.
