Line<br> A.<br> C.<br> D.<br> B.<br> Defined<br> Postulates<br> Theorems<br> Undefined<br> Terms
oksian1 [2.3K]

Answer: Undefined

Step-by-step explanation:

In geometry there are three  undefined terms that we use to define other terms:

  • Point → In geometry a point has a location but no dimension.
  • Plane →  A plane extends is a 2-dimensional surface that extends infinitely on both sides.
  • Line → A line is a one-dimensional undefined figure that extends infinitely in both the directions. It has length but has no width.

Hence, the correct option is "Undefined".

Find the equation of the line through (8,−6) which is perpendicular to the line y=x3−7.
ycow [4]

Answer:

y = (-1/3)(x + 10)

Step-by-step explanation:

The slope of the new (perpendicular) line is the negative reciprocal of the slope of the given line, which appears to be 3.  Thus, the perpendicular line has the slope -1/3.

Using the slope-intercept form y = mx + b, and substituting the givens, we obtain:

y = mx + b    =>    -6 = (-1/3)(8) + b, or

-6 = -8/3 + b.  We must solve for the y-intercept, b:

Multiplying all three terms by 3 removes the fraction:

-18 = -8 + 3b.  Thus, -10 = 3b, and so b must be -10/3.

The desired equation is    

y = (-1/3)x - 10/3, or

y = (-1/3)(x + 10)

What does $1.99 $1.99; × 10 =
AlladinOne [14]

Answer:

I'm going to assume that the question was $1.99 × 10 because $1.99 $1.99; × 10 is not possible, so if that was the question, the answer would simply be false. The answer I got for $1.99 × 10 was 19.9

Answer: 19.9
