Joan wants to reduce the area of her posters by one-third. draw lines to match the original dimensions in the left column with the correct new area in the right column. not all dimensions will have a match.

1) -------->

2) -------->

3) -------->

4) -------->

Step-by-step explanation:

Verify each case

case 1)

Find the area with the original dimensions

Reduce the area of the poster by one-third

therefore

-------->

case 2)

Find the area with the original dimensions

Reduce the area of the poster by one-third

therefore

-------->

case 3)

Find the area with the original dimensions

Reduce the area of the poster by one-third

therefore

-------->

case 4)

Find the area with the original dimensions

Reduce the area of the poster by one-third

therefore

-------->

the answer would be c:   ax + b = ax + c

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
