Kevan is 8
katie is 14
Melanie is 16

I think this is the answer.

Let's start by narrowing it down to make it simpler:

Kevin is 6 years younger than Katie

Melanie is twice as old as Kevin.

So, to start off with, Melanie is twice as old as Kevin. That would make Melanie 12 years old, and Kevin 6 years old. I'm not too sure about Katie, however. But this is what I got:

Kevin: 6 years old
Melanie: 12 years old
Katie: ?

Hopefully that helped a little! :)

Answer:

$100

Step-by-step explanation:

the equation to solve this is:

$y=12.5x+25$

$y=12.5x+25\\ =(12.5*6)+25\\ =75+25\\ =100$

(Assuming, of course, that this is a homework assignment and not you actually buying it cuz' in real life the numbers would be different from month to month)

Let {v1,v2,v3} be a set of vectors in Rn . If u is Span {v1,v2,v3}, show that 3u is in Span {v1,v2,v3}.(Hint: since you are told

ANTONII [103]

Answer:

See proof below

Step-by-step explanation:

We will use the hint. The statement of the hint holds true, as the linear span of a set of vectors T is equal to the set of linear combinations of vectors in T.

Denote the linear span of vectors with the curly brackets < >, that is, $span\{v_1,v_2,v_3\}:=$

Let $u\in$ , then u is a linear combination of v1,v2,v3, that is, there exist scalars $c_1,c_2,c_3\in \mathbb{R}$ such that $u=c_1v_1+c_2v_2+c_3v_3$ . Multiply by 3 in both sides to get $3u=3c_1v_1+3c_2v_2+3c_3v_3=d_1v_1+d_2v_2+d_3v_3$ , with $d_i=3c_i,i=1,2,3$

Since $c_1,c_2,c_3\in \mathbb{R}$ , $d_1,d_2,d_3\in \mathbb{R}$ as real numbers are closed under multiplication. Therefore 3u is a linear combination of the vectors $v_1,v_2,v_3$ , that is, $3u\in$

What is the gcf of 2a³ and a⁶

erastovalidia [21]

Answer: a^3

Step-by-step explanation:

The gcf of 2a^3 and a^6 is a^3 because a is seen both in the two numbers. and also a^3 can go in both numbers(2a^3) and (a^6)
