Answer:

y = -1 x = 4

Step-by-step explanation:

(X+3y=1) 5 Multiply this equation by 5 to cancel out the x

-5x+4y=-24

-5x + 4y= -24

+ 5x + 15y = 5 Add both equations together

19y = -19 Divide both sides by 19

y = -1

Plug -1 for y into one of the equations

x + 3(-1) = 1 Multiply 3(-1)

x - 3 = 1

+ 3 + 3 Add 3 to both sides

x = 4

Answer:

$x = \frac{1}{e}$

Step-by-step explanation:

$f(x) = {(lnx)}^{2}$

$f1st(x) = \frac{2 lnx }{x} = 0$

$x < 1 \: \: f1 < 0 \: \: de creasing$

$f2nd(x) = \frac{2 - 2 lnx}{ {x}^{2} } = 0$

$x < e \: \: f2 > 0 \: \: concave \: up$

So x<1 is the condition which contains x=1/e

Answer:

r= $2\sqrt{2}$

r= - $2\sqrt{2}$

Step-by-step explanation:

8= $r^{2}$

Square root both sides of the equation.

r= $2\sqrt{2}$

r= - $2\sqrt{2}$
