Answer:
(2.6, -2.7)
Step-by-step Explanation:
Let X represent the point which is 7/10 of the way from A to B.
AX to XB = 7:10 = AX/XB = 7/10.
Formula for internal division to find the coordinates is:
Where,
Substitute the values above into the stated formula to find x and y coordinates as follows:
The coordinates of the point 7/10 of the way from A to B are (2.6, -2.7)
Given expression: for x = 3 and y = –2
(6) Mistake did by Grayson:
In second step, first to do 3² and then multiply with 4.
But Grayson first multiply 4 with 3 and then squared the expression.
This is wrong.
(7) Mistake did by Emily:
In third step, first to multiply 2 with (–2) using BODMAS rule and then add with 36.
But Emily first added 36 with 2 which gives 38.
This is wrong.
(8) Mistake did by Pat:
In first step, the y value given is –2.
But Pat substituted y value is 2.
This is wrong.
(9) Correct evaluation:
This is the correct way to evaluate the given expression.
