Write these numbers in standard form 1. 200,000
2. 80,000
3. 900,000,000
4. 10,000,000,000

They are all in standard form

Two hundered thousand

eighty thousand

nine hundred million

ten billion

these are word forms

hope this helps

have a good day :)

Step-by-step explanation:

1. 2 × 10⁵

2. 8 × 10⁴

3. 9 × 10⁸

4. 1 × 10¹⁰

Step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

answer: y=4000x+14000
