You first have to know how long each bead is and if its inches, centimeters, ect.
What is the specific problem you are supposed to use the coordinates for?
Answer:
y=3x^2+34
3x+y-10=0
Step-by-step explanation:
Let the dryer cost x.
Then, the washer costs (x-77)
Together, they cost (x) + (x-77) = 873
2x-77 = 873 [subtract 77 from both sides]
2x = 796
x = 398
So the dryer costs $398
