PLZ HELP Which situation most likely cannot be represented by a linear function?

Anna gets paid $10 per hour.
Briar gets paid $100 for the day.
Constance gets paid whatever her Dad feels like giving her for that day, and this is partially based on how long she works.
Danica gets paid $20 for the day, plus $7 per hour.

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.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

the correct answer is $7.38
