Decrease R1400 in the ratio of 7:3

Step-by-step explanation:

Use A. D. T method

Add, Divide, Times (Back 2 The Ratio)

7+3=10

1400÷10=140

140×7=980

140×3=420

*Then Add The Times Final Answer Then If They Give You The Same Number That Was Asked 2 Decrease In Then Everything Is Fine

Answ3r for money : 5:9

Steped-bye-steped on my explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

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
