Let u = &lt;-9, 4&gt;, v = &lt;8, -5&gt;. Find u - v. <br> URGENT
Pie

To subtract vectors, you simply have to subtract correspondent coordinates.

So, if you have

u = \langle u_1,\ u_2,\ldots u_n\rangle ,\quad v = \langle v_1,\ v_2,\ldots v_n\rangle

the subtraction is simply

u-v = \langle u_1-v_1,\ u_2-v_2,\ldots u_n-v_n\rangle

So, in your case, we have

\langle-9,4\rangle-\langle 8,-5\rangle=\langle -9-8, 4+5\rangle=\langle -17,9\rangle

Kameryn types 75 words per minute and is just starting to write a term paper. Joe already has 510 words written and types at a s
AnnZ [28]

Answer:

Kameryn will have more words typed than Joe when the number of minutes exceeds 34.

Step-by-step explanation:

Let

x -----> the number of minutes

y ----> the total words typed

we know that

<em>Kameryn</em>

y=75x -----> equation A

<em>Joe</em>

y=60x+510 -----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B and solve for x

75x=60x+510

75x-60x=510

15x=510

x=34\ minutes

That means

For x=34 minutes

The amount of words written by Kameryn and Joe are the same.

therefore

For x > 34 minutes

Kameryn will have more words typed than Joe when the number of minutes exceeds 34.

I do not know if is a function or not. Please explain
bezimeni [28]
It is a function because in a function the x's do not repeat. So since there are no two numbers in the x column that are the same, yes it is a function.
