Answer:

B. 20x larger

Step-by-step explanation:

3x10^5 = 300000

3x + (x-8) = 23 how do I solve it
Ostrovityanka [42]
<span>3x + (x-8) = 23

Combine like terms first. You can combine 3x and x because they have the same variable.

4x - 8 = 23
Now add 8 to both sides.
4x = 31

Last step is to divide both sides by 4 to isolate the x.
4/4x = 31/4

x = 7.75 is the answer.</span>

Let T:R²-&gt;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).
