Answer:
y = 2/5x - 2
Step-by-step explanation:
Step 1: Write equation
2x - 5y = 10
Step 2: Solve for <em>y</em>
- Subtract 2x on both sides: -5y = 10 - 2x
- Divide both sides by -5: y = -2 + 2/5x
- Rewrite: y = 2/5x - 2
Answer:
y +2 = (1/2)(x +3)
Step-by-step explanation:
It is helpful to know that the point-slope form of the equation with slope m through point (h, k) is ...
... y -k = m(x -h)
You have a line with a slope of 1/2. The parallel line will also have a slope of 1/2, so m = 1/2. The point you want on your line is (-3, -2), so (h, k) = (-3, -2). Putting these values into the point-slope form gives you ...
... y -(-2) = (1/2)(x -(-3))
Simplifying this gives ...
... y +2 = (1/2)(x +3)

Answer:
The orders of magnitude are numbers of the form:
10^n
where n can be any integer number.
So we can write something like:
"A is n orders of magnitude above B
Now we have the quantities:
Amjed cards = 223
Latif cards = 8741
We want to find how many times more trading cards does Latif have than Amjed.
Then we need to look at the quotient between the number of cards of Latif and Amjed.
8741/223 = 39.2
Now we need to approximate this to the nearest 10^n number.
(..., 0.1, 1, 10, 100, 1000, ...)
The nearest one to 39.2 is 10.
So we can say that Latif's collection is 10.
and 10 = 10^1
then n = 1
Then we can say that Latif's collection is one order of magnitude above Amjed's collection.
