Answer:
option (2) is correct.
is in the scientific notation form.
Step-by-step explanation:
Given: Some expressions
We have to choose which expressions is written in scientific notation.
For an expression to be in scientific notation the most important requirement is that the whole number is between 1 and 10, but not including 10.
that is , 1 ≤ a < 10 and n is integer.
Thus, out of given only is in the scientific notation form.
Thus, option (2) is correct.
Answer:
6 x 10^5
Step-by-step explanation:
7 x 10^6 is 7,000,000 and 6 x 10^5 is 600,000. The one that is closer is 6 x 10^5
Answer:
y = 3x - 2
Step-by-step explanation:
Given the points :
(2,4) and (6,16).
x1 = 2 ; y1 = 4 ; x2 = 6 ; y2 = 16
Y = mx + b
m = slope
b = intercept
m = Rise / Run
Rise = y2 - y1 = 16 - 4 = 12
Run = x2 - x1 = 6 - 2 = 4
m = 12 / 4 = 3
Y = 3x + b
4 = 3(2) + b
4 = 6 + b
4 - 6 = b
b = - 2
Equation becomes ;
y = 3x - 2
