A student simplifies the given expression. Which statement BEST describes the error in the student's work? 12 + 24 ÷ 6(4) 36 ÷ 2
4 36/24 = 3/2 A) The student added before multiplying.
B) The student multiplied before dividing.
C) The student divided before multiplying.
D) The student simplified the answer incorrectly.
E) The student added incorrectly.
A. The student added before multiplying. If they had multiplied 6 and 4 first, the next step would have been too divide. But since they added first, they got 36/24 or 3/2 when the answer should be 13.
2) y= 3x+c replace x and y to find c , 5=3(2)+c C= -1 Y=3x-1
3) find slope first m=y2-y1/x2-x1 = 0-(-1)/-2-1 = 1/-3 and now you have y= -1/3x+c to find c just replace any of the given points , 0= -1/3(-2)+c C= -2/3 and so y= -1/3x-2/3
