Let T:R²->R² be a linear transformation ,and assume that T (1,2)=(-1,1) and T(1,-1)=(2,3)

zavuch27 [327]

Answer:

(-4,-1)

Step-by-step explanation:

We are given T(1,2)=(-1,1) and T(1,-1)=(2,3) and T is a linear transformation.

This implies for scalars a and b that

T(a(1,2)+b(-1,1))=aT(1,2)+bT(-1,1)

T((a,2a)+(-b,b))=a(-1,1)+b(2,3)

T((a-b,2a+b))=(-a,a)+(2b,3b)

T((a-b,2a+b))=(-a+2b,a+3b)

This means we should be able to solve the system below to find a and b for T(3,3):

a-b=3 and 2a+b=3

Add equations to eliminate b and solve for a:

3a=6

Divide 3 on both sides:

a=2

If a-b=3 and a=2, then b=-1.

Plug in a=2, b=-1:

T((a-b,2a+b))=(-a+2b,a+3b)

T((2--1,2×2+-1)=(-2+2×-1,2+3×-1)

T(3,3)=(-4,-1).

(Math) How do you describe a function? Must be in 3 complete sentences!

Alla [95]

A function could be linear or not. Is the rate of change consistent, increasing, or decreasing? Is does the symbol have one minimum value or maximum value, or several such values?

X/9+3<4 what is the solution to the ineqaulity

11111nata11111 [884]

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to find the solution to the inequality:

$\star~\large\pmb{\cfrac{x}{9}+3 < 4}$

$\triangle~\fbox{\bf{KEY:}}$

First, subtract 3 from both sides, then multiply both sides by the denominator.

<u>Step 1.</u>

<u></u>

<u></u> $\star~\large\pmb{\cfrac{x}{9} < 4-3}$

$\star~\large\pmb{\cfrac{x}{9} < 1}$

<u>Step 2.</u>

<u></u>

<u></u> $\star~\large\pmb{\cfrac{x}{9}\times9 < 1\times9}$

Notice that on the left, the 9s cancel, and we're left with x.

<u>Step 3.</u>

<u></u>

<u></u> $\star~\large\pmb{x < 9}$

This is the solution.

Hope it helps you out! :D

Whats the best way to do this operation?---------------------------------

SashulF [63]

$400 - $20 = $380 ( The original charge subtract the amount he paid. )
$380 + $18 = $398 (The amount unpaid plus another charge equal total amount unpaid.)
$398 x 0.02 = $7.96 (The amount unpaid multiply the percentage of interest = amount of interest.)

Phillip charged $7.96 interest on his second bill.
