Answer:

no the sign should say 12 percent of people voted darnells

Step-by-step explanation:

because if the population is 10 thousand and you take 25 percent that will put the total amount of people who can vote at 7500 and then take 20 percwnt of that and it will put you at 1500 people who can vote and then if you take 80 percent of 1500 people who can vote than only 1200 of them voted for Darnell which would make it only 12 percent of people voted for darnells

Determine if the given function is a linear transformation. t(x1, x2, x3) = (−2x2, 6x3)

Zepler [3.9K]

$T:\mathbb R^3\to\mathbb R^2$ will be linear if for any $\mathbf x,\mathbf y\in\mathbb R^3$ and constants $a,b\in\mathbb R$ , we have

$T(a\mathbf x+b\mathbf y)=aT(\mathbf x)+bT(\mathbf y)$

Let $\mathbf x=(x_1,x_2,x_3)$ and $\mathbf y=(y_1,y_2,y_3)$ , and let $a,b$ be any two scalars. Then

$a\mathbf x+b\mathbf y=(ax_1+by_1,ax_2+by_2,ax_3+by_3)$

By definition of $T$ , we have

$T(a\mathbf x+b\mathbf y)=(-2ax_2-2by_2,6ax_3+6by_3)$
$T(a\mathbf x+b\mathbf y)=(-2ax_2,6ax_3)+(-2by_2,6by_3)$
$T(a\mathbf x+b\mathbf y)=a(-2x_2,6x_3)+b(-2y_2,6y_3)$
$T(a\mathbf x+b\mathbf y)=aT(\mathbf x)+bT(\mathbf y)$

Therefore $T$ is a linear transformation.

1) -6y + 17 = 3y - 10

Subtract 3y from both sides.

-6y - 3y + 17 = -10

Subtract 10 from both sides.

-6y - 3y = -12 - 10

Simplify.

-9y = -27

Divide both sides by -9.

y = 3

2) 3x - 32 = -7x + 28

Add 7x to both sides.

3x + 7x - 32 = 28

Add 32 to both sides.

3x + 7x = 28 + 32

Simplify.

10x = 60

Divide both sides by 10.

x = 6

3) 3.2 - 16 = 4a

Simplify.

-12.8 = 4a

Divide both sides by 4.

a = -3.2

4) 16.8 - v = 6v

Add v to both sides.

16.8 = 6v + v

Simplify.

16.8 = 7v

Divide both sides by 7.

v = 2.4

To check all answers, simply plug in the value of the variable that you found, then simplify.
