Brian weighs himself at 82kg to the nearest kg. What is the most he could weigh?
Give the upper bound as your answer.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
