Which equations represent functions?
2 answers:
Hello,
B, C, and D are the correct answers. Option D is the parent function of a parabola which is a function (it passes the vertical line test). Option C is also a parabola (shifted a unit to the right) and Option B is a linear graph which is a function. Option A doesn't pass the vertical line test and therefore isn't a function. I attached an image in case you weren't sure what the vertical line test is. Hope this helps!

Answer:
28 minutes spent in washing the dishes.
Step-by-step explanation:
Given the table
Chore time in minutes
Sweeping 42
Dishes ?
Amanda spent a total of 70 minutes competing her chores this week
Total of 70 minutes spent
42 minutes spent in sweeping . to find the number of minutes Amanda spent in washing the dishes , subtract 42 minutes from the total time spent
let x be the number of minutes spent washing the dishes
To solve for x , subtract 42 from both sides
28 minutes spent in washing the dishes.
