<span>The correct answer is x= -5, y=4.

Explanation:
Since y is isolated in both of these equations, we will set them equal to one another to solve:
-2x-6=x+9.

Add 2x to both sides:
-2x-6+2x=x+9+2x
-6=3x+9.

Subtract 9 from both sides:
-6-9=3x+9-9
-15=3x.

Divide both sides by 3:
-15/3 = 3x/3
-5=x.

Substitute this into the second equation; y= -5+9 = 4.</span>

Answer:

x= -5 , y= 4.

Step-by-step explanation:

Given: y = x+9y and   y = -2x-6 .

To find: variable x and y.

Solution: we have given that

 y=x+9 -----Equation (1)

y = -2x-6 ------Equation(2)

Equating both equation

x +9 = -2x -6

On adding  2x both sides

x + 2x + 9 = -6

3x + 9 = -6

On subtracting both sides by 9

3x + 9 -9 = -6 -9

3x = - 15

On dividing both sides by 3

x = -5

Now, on substituting x =-5 in equation 1

y = -5 + 9

y= 4

( -5, 4)

Therefore, x= -5 , y= 4.

Consider the function g(x) = (x-e)^3e^-(x-e). Find all critical points and points of inflection (x, g(x)) of the function g.
Elden [556K]

Answer:

The answer is "cirtical\  points \ (x,g(x))\equiv  (e,0),(e+3,\frac{27}{e^3})"

Step-by-step explanation:

Given:

g(x) = (x-e)^3e^{-(x-e)}

Find critical points:

g(x) = (x-e)^3e^{(e-x)}

differentiate the value with respect of x:

\to g'(x)= (x-e)^3 \frac{d}{dx}e^{e-r} +e^{e-r}  \frac{d}{dx}(x-e)^3=(x-e)^2 e^{(e-x)} [-x+e+3]

critical points g'(x)=0

\to (x-e)^2 e^{(e-x)} [e+3-x]=0\\\\\to e^{(e-x)}\neq 0 \\\\\to (x-e)^2=0\\\\ \to [e+3-x]=0\\\\\to x=e\\\\\to x=e+3\\\\\to x= e,e+3

So,

The critical points of (x,g(x))\equiv  (e,0),(e+3,\frac{27}{e^3})

Which function equation is represented by the
seraphim [82]

Answer:

f(x) = 20(3/5)^x

Step-by-step explanation:

When x = 1, f(x) = 12

f(x) = 20(3/5)^1

= 20 * 3/5

= 60/5

= 12.

so f(x) = 20(3/5)^x is the answer.
