Elinor determined that a triangle with side lengths 6, 10, and 8 does not form a right triangle. 62 + 102 = 82 36 + 100 = 64 136

≠ 64 Is her answer correct? No, she should have added 82 and 102 and compared that to 62. No, she should have subtracted 102 from 82 and compared that to 62. No, she should have added 62 and 82 and compared that to 102. Yes, she is correct.

Answer:

incorrect

Step-by-step explanation:

To determine if the triangle is right

If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right, that is

longest side = 10 and 10² = 100

6² + 8² = 36 + 64 = 100

Thus the triangle is right.

She should have added 6² and 8² and compared that to 10²

Find the point of intersection (if any) of the following pairs of lines: a) x – 2y +1=0 2x + 3y – 7 = 0 b) x-2y+11=0 -x+2y-13 =
pychu [463]

Answer:

a) (11/7, 9/7)

b) There's no point of intersection

Step-by-step explanation:

a) x - 2y + 1 = 0

2x + 3y - 7 = 0

To find the point of intersection, we need to solve the system of equations  and the result will be the point of intersection (x,y)

x-2y+1=0\\x= 2y-1

Now we substitute x in the second equation:

2x+3y-7=0\\2(2y-1)+3y-7=0\\4y-2+3y-7=0\\7y-9=0\\y=9/7

Now we substitute y in our first equation.

x-2y+1=0\\x-2(9/7)+1=0\\x-18/7+1=0\\x=18/7-1\\x=11/7.

The point of intersection is (11/7, 9/7)

b) x -2y +11 =0

-x + 2y - 13 =0

We are going to follow the same procedure:

x-2y+11=0\\x=2y-11

-(2y-11)+2y-13=0\\-2y+11+2y-13=0\\0y=2\\0=2

Since this system of equations doesn't have a solution, the system has no point of intersection.
