Answer:
All real numbers
Step-by-step explanation:
Distribute the -2 to the parentheses:
-12d - 6 = -2(d + 3) - 10d
-12d - 6 = -2d - 6 - 10d
Add like terms:
-12d - 6 = -12d - 6
Since each side is equivalent to -12d - 6, the answer is all real numbers
Answer:
Step-by-step explanation:
f(-9+h)= (-9+h)² = h²-18h+81
f(-9+h)-f(-9)=h²-18h+81 -81 because : f(-9) = (-9)² = 81
f(-9+h)-f(-9)=h²-18h
(f(-9+h)-f(-9))/h=(h²-18h)/h = h(h-18)/h =h-18
lim (f(-9+h)-f(-9))/h = lim(h-18= - 18
h→0 h→0
Option B:
A ray has two endpoints and extends infinitely in both directions.
Solution:
Option A: Two lines that intersect are called skew lines.
It is false because,
Two lines are said to be skew lines if they do not intersect and do not lie in the same plane.
Option B: A ray has two endpoints and extends infinitely in both directions.
It is false because,
A ray has one endpoint and extends infinitely in one direction.
Option C: A line is a set of points that extends infinitely in both directions.
It is false true.
A line is a set of points that extends infinitely in both directions.
Option D: Two lines in the same plane are said to be perpendicular if they never intersect.
It is false because,
Two lines are said to be perpendicular if they are intersect.
Hence Option B is true. A line is a set of points that extends infinitely in both directions.
Answer:
x = -2
Step-by-step explanation:
-2x + 4x = -4 + 0
2x = -4
2x/2 = -4/2
x = -2
Hope this helps.
