The difference of twice a number and 3 is -21

Step-by-step explanation:

The word difference means subtractions. For example, the difference of 8 and 3 is 5. In equation form, this means " 8 - 3 = 5 "To say "twice a number" means to have a number twice, which is multiplication. Since we don't know what the number is, we will call it x. So to put the proposed question in equation form, we would say "2x - 3 = -21"

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

one set of data has more variation than the other. hope this !
