Answer:
Three non-collinear points determine a plane.
Step-by-step explanation:
This statement means that if you have three points not on one line, then only one specific plane can go through those points. The plane is determined by the three points because the points show you exactly where the plane is
Answer:
I am pretty sure it is dependent
Let me know if it is wrong.
Answer:
-7
Step-by-step explanation:
The line (y-1)=(2/3)(x+1) contains point (a,-3)
=> (-3-1) = (⅔)(a+1)
-4 = (⅔)(a+1(
(a+1)= -4 ÷ ⅔
a + 1 = -4 × 3/2
a+ 1 = -6
a = -6-1
a = -7
Answer:
99°
Step-by-step explanation:
∠7 and ∠8 are a linear pair, so are supplementary. Numbers are assumed to be degrees.
∠7 + ∠8 = 180
2x+15 + 3x = 180 . . . . . substitute given values
5x = 165 . . . . . . . . . . . . subtract 15, collect terms
x = 33 . . . . . . . . . . . . . . . divide by the coefficient of x
∠8 = 3x = 3·33 = 99 . . . . . degrees
12,000 is this what you mean? if not i can just edit this and change it
