Steven and Bob both have a Pokemon card collection. The number of Pokemon cards in Steven's collection can be represented by x.
Arada [10]

Answer: 48

Step-by-step explanation:

The number of Pokemon cards in Steven's collection = x

The number of cards in Bob's collection is 4 times the amount in Steven's collection= 4x

The total number of Pokemon cards in both collections = 240

x + 4x = 240

5x = 240

x = 240/5

x = 48

The number of cards in Steven's collection is 48

Stolb23 [73]

Answer:

v=a+ 2e1= [3 1 1 1] x^{T}.

Step-by-step explanation:

Let a = ^{}\left[\begin{array}{ccc}\\1&1&1\\\end{array}\right] ^{T}and we know that\alpha=±║α║₂= 2.

As we have gone over in class, the formula for v is v= a-\alphae1

with the sign of chosen to avoid subtraction. This gives v=a+ 2e1= [3 1 1 1] x^{T}.
