Mathematics

-7 = x/2 + 1

Subtract one from both sides

-8 = x/2

Multiply two on both sides

-16 = x

Answer, x = -16

Checking,

-7 = (-16/2) + 1

-7 = -8 + 1

-7 = -7

Can y’all help me pls

bija089 [108]

Answer:

The answer is (1,-9)

Step-by-step explanation:

First, you have to plug -9x to y because y = -9x. Then multiply

-6(-9x) = 54x

-8x + 54x = 46

46x = 46

x = 1

Plug 1 into the first equation to find the value of y.

y = -9(1)

y= -9

Which graph shows the solution to the system of linear inequalities?<br> y>2/3x+3

Andrews [41]

Answer:

Graph attached.

Step-by-step explanation:

y > $\frac{2}{3}$ x + 3

When x = 0 , y = 3

When y = 0 , x = -4.5

Graphing the two points (0, 3) and (-4.5, 0) gives the graph attached below:

The shaded part is the wanted region.

Use Lagrange multipliers to find the maximum and minimum values of f(x,y)=x+4y subject to the constraint x2+y2=9, if such values

Vesnalui [34]

The Lagrangian is

$L(x,y,\lambda)=x+4y+\lambda(x^2+y^2-9)$

with critical points where the partial derivatives vanish.

$L_x=1+2\lambda x=0\implies x=-\dfrac1{2\lambda}$

$L_y=4+2\lambda y=0\implies y=-\dfrac2\lambda$

$L_\lambda=x^2+y^2-9=0$

Substitute $x,y$ into the last equation and solve for $\lambda$ :

$\left(-\dfrac1{2\lambda}\right)^2+\left(-\dfrac2\lambda\right)^2=9\implies\lambda=\pm\dfrac{\sqrt{17}}6$

Then we get two critical points,

$(x,y)=\left(-\dfrac3{\sqrt{17}},-\dfrac{12}{\sqrt{17}}\right)\text{ and }(x,y)=\left(\dfrac3{\sqrt{17}},\dfrac{12}{\sqrt{17}}\right)$

We get an absolute maximum of $3\sqrt{17}\approx12.369$ at the second point, and an absolute minimum of $-3\sqrt{17}\approx-12.369$ at the first point.
