Respuesta :

Answer:

Steve lose 8.4 pounds of weight in 4 weeks.

Step-by-step explanation:

Given:

Melt Away Weight Loss uses the regression equation [tex]y = 1.8x + 1.2[/tex] to predict the weight loss of their clients.

[tex]x[/tex] = the number of weeks on a diet.

[tex]y[/tex] = the total number of pounds lost.

Now, to find the weight Steve lose in 4 weeks.

Number of weeks ([tex]x[/tex]) = 4.

Now, solving the equation by substituting the value of number of weeks:

[tex]y=1.8x+1.2[/tex]

[tex]y=1.8(4)+1.2[/tex]

[tex]y=7.2+1.2[/tex]

[tex]y=8.4.[/tex]

The total number of pounds lost = 8.4.

Therefore, Steve lose 8.4 pounds of weight in 4 weeks.
