Answer:

x ≤ 14/23
or
x = ( -oo, 14/23]

Step-by-step explanation:

<u>Solving is steps</u>

-23x + 13 ≥ -1 ⇒ add -13 to both sides
-23x ≥ - 1 - 13
-23x ≥ - 14 ⇒ divide both sides by - 23, inequality sign reverses
x ≤ 14/23 ⇒ answer

x = ( -oo, 14/23] ⇒ answer as set

Solve x. 10(2x - 4) = 100x

mr_godi [17]

Answer:

x=1/2

Step-by-step explanation:

Distribute the 10. it will be 20x-40=100x. Subtract 20x from both sides. it will be 40=80x. Divide by 80 to leave the x by itself. x=40/80...in simplify form....its 1/2

14. Let R^2 have inner product defined by ((x1,x2), (y,, y2)) 4x1y1 +9x2y2 A. Determine the norm of (-1,2) in this space B. Dete

Vitek1552 [10]

The norm of a vector $\vec x$ is equal to the square root of the inner product of $\vec x$ with itself.

a. $\|(-1,2)\|=\sqrt{\langle(-1,2),(-1,2)\rangle}=\sqrt{4(-1)^2+9(2)^2}=\sqrt{40}=2\sqrt{10}$

b. $\|(3,2)\|=\sqrt{\langle(3,2),(3,2)\rangle}=\sqrt{4(3)^2+9(2)^2}=\sqrt{72}=6\sqrt2$
