Answer:
3) x^2-yz/z^2
x = -3, y = 5 and z = -2 plug in these values
-3^2 -5(-2) /-2^2
= -1/4
decimal form: -0.25
4) x^2+y^2+z^2/xyz
x = -3, y = 5 and z = -2 plug in these values
-3^2+5^2+-2^2/-3*5*-2
= 2/5
decimal form: 0.4
5) x+y/z + y+z/x
x = -3, y = 5 and z = -2 plug in these values
(-3+5/-2)+(5+(-2)/-3)
= -2
6) 2x+y-z/x-3y+z
x = -3, y = 5 and z = -2 plug in these values
2(-3)+5-(-2)/-3-3(5)+(-2)
= -1/20
decimal form: -0.05
Turn them into improper fractions and then flip 27/8 to its reciprocal (8/27) and then multiply.
<span>The correct option is: (C) a⊥b, by Perpendicular Transversal Theorem
Explanation:
Perpendicular Transversal Theorem states that in a plane, if a line is perpendicular to one of two parallel lines, then it is perpendicular to the other line also.
As the line b is perpendicular to the line c and the line c is parallel to the line a, hence the line a is perpendicular to the line b. Therefore, the correct option is (C) a⊥b, by Perpendicular Transversal Theorem
