x >= -4
The arrow points to the right meanings that on the graph the arrow will go towards the right.
You could also think about it that x is greater than or equal to -4, so the arrow will be going towards the positive numbers from -4 meaning the arrow will go towards the right.
Also since it is greater than or equal to the circle will be a solid, filled in circle.

why is iron usually made into alloy for commercial uses?
A iron is too lightweight of a metal
B iron is a scare natural resource
C iron reacts easily with air and water
D iron by itself is to hard
answer fast please
Answers
Answer is C.
Iron is typically alloyed for commercial uses because it reacts easily with air and water, leading to corrosion. By creating alloys such as steel with added elements like carbon and chromium, iron becomes more robust and rust-resistant, lending itself to a wider range of applications.
The reason iron is usually made into an alloy for commercial uses is that iron reacts easily with air and water, which is option C. Commercial alloys of iron, like steel, are produced by adding elements such as carbon and metals like manganese, chromium, nickel, tungsten, molybdenum, and vanadium. These elements create an alloy that is more resistant to corrosion (rusting), and they can be engineered to have different properties suitable for specific applications. For example, stainless steel contains chromium which helps in forming a protective oxide layer on the surface, thereby protecting the base iron from rusting.
While wrought iron, which is a commercially pure iron containing less than 0.2% carbon, is quite resistant to rust and is malleable and ductile, it has largely been replaced by mild steel. Mild steel, though not as corrosion-resistant as true wrought iron, is more cost-effective and widely available. Therefore, the commercial use of iron predominantly involves its transformation into alloys that benefit from enhanced strength, durability, and corrosion resistance.

Mr. Rodriguez is packing bags of snacks for his children’s lunchboxes. If he has 20 blueberries and 30 grapes, what is the maximum number of bags of snacks that he can pack so that each bag has the same number of blueberries and grapes?
Answers
If each bag has 4 blueberries and 6 grapes.
With equal distribution of blueberries and grapes, Mr. Rodriguez can pack maximum of 10 bags of snacks.
What is ratio?Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
Given is that Mr. Rodriguez is packing bags of snacks for his children’s lunchboxes and for that he has 20 blueberries and 30 grapes.
Now, we have -
Number of blueberries = n[b] = 20 blueberries
Number of grapes = n[g] = 30
For equal distribution, there should be a ratio of → n[b]/n[g] = 20/30 = 2/3
Or we can write it as 2 : 3. This means that in each box there should be 2 blueberries and 3 grapes.
The maximum number of bags [x] that Mr. Rodriguez can pack can be calculated as -
2x + 3x = 20 + 30
5x = 50
x = 10
Therefore, with equal distribution of blueberries and grapes, Mr. Rodriguez can pack 10 bags of snacks.

40 is 160% of what number?
Answers
40 ÷ 160% = 40 ÷ (160 ÷ 100) = (100 × 40) ÷ 160 = 4,000 ÷ 160 = 25.
The answer is 25.
writing this in equation form you have 160% times X = 40
so 160% * x =40
160% as a decimal = 1.60
so 1.60 * x = 40
to find x divide both sides by 1.6
40 /1.6 = 25
the number is 25
