GrogVix [38]

Answer: 8.8 pounds.

Step-by-step explanation:

Hi, to answer this question, first we have to divide the total weight loss in a week (28 kg) by 7 (days in a week).

28 /7 = 4 kg per day

The group lost 4 kg each day.

Finally we have to convert the result into pounds.

Since 1 kg = 2.2 pounds

4 kg x 2.2 = 8.8 pounds.

Feel free to ask for more if needed or if you did not understand something.

Explain why y +1 = 1.2(x + 2) and y- 5 = 1.2(x – 3) represent the same line, despite having
Shtirlitz [24]

Answer:

They have the same slope

Step-by-step explanation:

The standard equation of a line in point-slope form is expressed as;

y-y0 = m(x-x0)

We can see that both equations given are written in this form with a slope of 1.2. For two lines to be equal, they must have the same slope no matter the point on the lines. Hence the two equations are equal since they have different slopes.
