a) The function that represent this situation is y = 90 + 8x.
b) His weight be after 8 weeks is 154 lbs.
<u>Step-by-step explanation:</u>
It is given that,
- He started at 90 kilograms.
- And gained weight at a constant rate of 8 lbs a week.
a) Write a function to represent this situation. Use x and y as your variables.
- Let 'x' be the number of weeks he gained weight.
- Let 'y' be the total weight.
Hence the equation can be framed as,
Total weight = starting weight + weight gained in x weeks.
We know that, each week he gains 8 lbs. Therefore, for 8 weeks he gained 8x lbs of weight.
⇒ y = 90 + 8x.
∴ The function that represent this situation is y = 90 + 8x.
b) What would his weight be after 8 weeks?
To find his week after 8 weeks, substitute x=8 in the function y = 90 + 8x.
⇒ 90 + 8(8)
⇒ 90 + 64
⇒ 154 lbs.
∴ His weight be after 8 weeks is 154 lbs.
Using the slope-intercept form, y=mx + b to find the slope I found that correct answer is 2/5.

Answer:
Step-by-step explanation:
<h3>
Convert kilometer to miles:</h3>
1 km = 0.62 mi
So, to convert 6 km to mi, multiply 6 by 0.62.
6km = 6* 0.62
= 3.72 mi
<h3>Convert liter to gallon:</h3>
1 L = 0.26 gal
To convert 2.5 L to gallon, multiply 2.5 by 0.26.
2.5 L = 2.5 * 0.26
= 0.65 gal
<h3>Convert pound to kilogram:</h3>
1 lb = 0.45 Kg
To convert 90 lb to Kg, multiply 90 by 0.45.
90 lb = 90 *0.45
= 40.5 Kg
