Explain why lim
x²-2x-35
X-7
X-7
lim (x+5), and then evaluate lim
X-7
x² -2x-35
x-7
x-7
Choose the correct answer below.
A.
x²-2x-35
The limits lim
X-7
X-7
and lim (x+5) equal the same number when evaluated using
X-7
direct substitution.
B. Since each limit approaches 7, it follows that the limits are equal.
C.
The numerator of the expression
X-2x-35
X-7
simplifies to x + 5 for all x, so the limits are
equal.
D.
Since
x²-2x-35
X-7
= x + 5 whenever x 7, it follows that the two expressions evaluate to the
same number as x approaches 7.
Now evaluate the limit.

Define a vector ♬ to be a column vector. Then, the following properties hold: • cu with c some constant, is equal to a new vector where every element in cv is equal to the corresponding element in & multiplied by c. For example, 2 2 = ● √₁ + √2 is equal to a new vector with elements equal to the elementwise addition of ₁ and 2. For example, 問 2+4-6 = The above properties form our definition for a linear combination of vectors. √3 is a linear combination of √₁ and √2 if √3 = a√₁ + b√2, where a and b are some constants. Oftentimes, we stack column vectors to form a matrix. Define the column rank of a matrix A to be equal to the maximal number of linearly independent columns in A.
