Answers

For the following exercises, use the given vectors a and $\mathbf{b}$ to find and express the vectors $\mathbf{a}+\mathbf{b}, \quad 4 \mathbf{a}, \quad$ and $-5 \mathbf{a}+3 \mathbf{b}$ in component form.
$$
\mathbf{a}=\langle- 1,-2,4\rangle, \quad \mathbf{b}=\langle- 5,6,-7\rangle
$$

First, you might want to experience this, um, into complete form. So Hey, it's nothing. Okay, which is 00 and one. He is next. If I which is that if 100 So now you can write a plus B. It's just some off this, too, which is negative. +10 negative one for a is four times disruptor, which is 0094 and, uh, next five, a past three p iss five off this one, which is 005 us three times here. So it's negative 300 as if you're 30 five.

Okay, we have a is equal to three comma *** to come forth and be a physical to limit of five comma. Six Common *** line for asked for a plus B. Well, that's just three minus +52 plus six and four minus nine. Does that give me minutes? Negative. Two comma for common agriff eyes. Now we know that for a physical to 12 negative eight and 16 and we have that five. Hey is equal to 15 comma. 10. Come on, *** Tony and three B is equal to taking a 15 comma, 18 comma 29 27. So Mega five a was three B that becomes like the 15 minus 15 and plus 18. Is it a 20 minus 27? That's equal to the negative. 30 28. Come on, the 47.

I don't think even execution said stupid. So just fall down this, like, who is five times using Skillern modification. We show patrons to intake among 16. This 25. 20? No, you just have these directors. So just 20 less. Two different 1 16 less trendy once in living this reading briefly. Give justice. Now, after about 19 these two numbers we get nine times, right? A round of this fine, more or less. Spread it off by expired place or square. Just don't quite this 16 you don't want.

Instead of thinking that expression since you about your just three times in commodity less times You think this getting a traditional deploying place he had asking said it is It's this eight. No, Just add these two sectors just since Yes. Eight. Yes. So defined this. Get the end set. This 14. So do you want
