Liz's math test included a survey question asking how many hours students spent studying for the test. The scatter plot below shows the relationship between how many hours students spent studying and their score on
the test. A line was fit to the data to model the relationship.

Which of these linear equations best describes the given model?
A) ŷ = 10x + 20
B) ŷ = 20x + 20
Or C) ŷ = -20x + 20

Based on this equation, estimate the score for a student that spent 3.8 hours studying.
Round your answer to the nearest hundredth.

idk lol

step-by-step explanation:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

eww xbox also eww dayz

step-by-step explanation:

just for that im not answering

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.
