Find the vector from the point (-4,8,7) to the point (6,5,5). enter the coordinates: equations of lines: consider the vector equation of the line through the two points listed above. for each equation listed below, answer t if the equation represents the line, and f if it does not. here is the list of questions: (x, y, z) = (-4, 8, 7) + t (-10, +3, +2) (x, y, z) = (6, 5, 5) +t (10, -3, -2) (x, y, z) = (-4, 8, 7) + t (6, 5, 5) (x, y, z) = (-4, 8, 7) +t (10, -3, -2) (x, y, z) = (6, 5, 5) +t (-4, 8, 7)

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

depends what are you allowed to do ?

in order to do a equation you have to get what has has a letter to one side and for a traversal you have to know that each line is the same as each opposing side
