43. This graph shows a proportional relationship between the number of gallons of gasoline used (g) and the total cost of gasoline (c).Find the
constant of proportionality (r). Using the value for r, write an equation in the
form of c = rg that represents the relationship between the number of
gallons of gasoline used (g) and the total cost (c).*
(A) $3.00 per gallon
(B) $3.13 per gallon
(C) $3.23 per gallon

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

answer: what are the following choices
