This student is incorrect because there is no number that you can multiply by 2 to get 5. Therefore, the proper point would be (1, 5) as the equation is setup as x+2y=5, so x must equal 1, and y must equal 2. Now to check if its correct:
1+2(2)=5
2x2=4
1+4=5
It is correct, so the answer is (1, 5)
Answer:
Step-by-step explanation:
(3, 0) (0, 2)
(2-0)/(0-3) = 2/-3= -2/3
y - 0 = -2/3(x - 3)
y = -2/3x + 2
You need to subtract the total number of pennies they have to the number of pennies they wrapped
Total: 592+128=720
Subtract total to the number of pennies wrapped
720-250=470
You can round 470 up to get 500 pennies that the girls had left
The answer is B
