Which situations can be represented by the proportion 1/2 = 1/4? Check all that apply. If 8 people can wash a car in •1/4 hour, then 4 people can wash the same car in 1/2 hour.

•If 8 people can eat 1/2 of a watermelon, then 4 people can eat 1/4 of the watermelon.

•If 1/2 pound of steak costs $8, then 1/4 pound of steak costs $4.

•If 1/2 a pot holds 4 fluid Ounces of water, then 1/4 of the pot holds 8 fluid ounces.

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

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
