Question

Answer correctly / explain a little.

Answer 1

Answer:

B) 8.4 lbs

Step-by-step explanation:

given:

y = 1.8x + 1.2

where,

x = number of weeks,

y = total lbs lost

in 4 weeks, x = 4 (substitute into equation):

y = 1.8x + 1.2

y = 1.8 (4) + 1.23

y = 7.2 + 1.2

y = 8.4 lbs

Answer 2

Answer:

B) 8,4 pounds

Step-by-step explanation:

$y = 1,8[4] + 1,2; 8,4 = y \\ \: \: \: \: \: \: \: \: \: \: \: 7,2$

You substitute four weeks in for x, multiply that by 1,8 to get 7,2, and finally add 1,2 to it, to get the total weight loss of 8,4 pounds [3,81018 kilograms].
