Answer:
Undefined
General Formulas and Concepts:
- Slope of horizontal and vertical lines
Step-by-Step Explanation:
A vertical line always has an undefined slope. There is no such value m of slope that can make a vertical line, and thus we reach the conclusion of undef.
Answer:
C. (3x+12) + x = 180
Step-by-step explanation:
the 2 angles create a straight line which is 180 degrees, so (3x+12) + x = 180
Formula = (a + b)^2 = a^2 + 2ab + b^2
x^2 + 4x + 4 + 9 = 0
x^2 + 4x + 13 = 0
Answer:
dm
Step-by-step explanation:
A square's diagonal cuts across the square, making two right triangles where the diagonal is the hypotenuse.
We have a right triangle with a hypotenuse of 29, and two legs that are the same length (because they are sides of a square)
So, we can use pythagoreans theorem to find the lengths of the legs, or sides of the square.
Now that we have a side length of 
, we just have to multiply that by 4, since a square has 4 sides. This leaves us with a final perimeter of:
Answer:
perpendicular; their slopes are opposite reciprocals
Step-by-step explanation:
y = (2/3)x + 8
rewrite the first equation to be in point-slope form
3x + 2y = 7
2y = -3x + 7
y = (-3/2)x + (7/2)
their slopes are (2/3) and (-3/2) -- opposite reciprocals
