Answer:
SOLUTION: Postulate 2.5 states if two points lie in a plane, then the entire line containing those points lies in that plane. Therefore, the statement is always true. ... The intersection of two planes can be a point. SOLUTION: Postulate 2.7 states if two planes intersect, then their intersection is a line.

Answer:
C
Step-by-step explanation:
Here, we want to reflect over the y-axis
by reflection over the y-axis, (x,y) becomes (-x,y)
Thus, we simply are going to negate the x values of the points given
So the correct answers are;
P’(4,-8)
Q’ (6,6)
R’ (-1,-7)

Answer:
a = 1 b = -1.
Step-by-step explanation:
Suppose the quotient when you divide x^4+x^3+ax+b by x^2 + 1 is
x^2 + ax + b then expanding we have:
(x^2 + 1)(x^2 + ax + b)
= x^4 + ax^3 + bx^2 + x^2 + ax + b
= x^4 + ax^3 + (b + 1)x^2 + ax + b Comparing this with the original expression:
x^4 + x^3 + 0 x^2 + ax + b Comparing coefficients:
a = 1 and b+ 1 = 0 so b = -1.
