<h2>Answer: x = 5</h2><h3>Explanation: </h3><h3>First, you subtract 10 from both sides. </h3><h3>Next, you simplify 20 - 10. </h3><h3>20 - 10 = 10. </h3><h3>Then, you divide both sides by 2. </h3><h3>x = 10/2</h3><h3>Now, simplify the equation.</h3><h3>Giving you the dividend of 5. </h3><h3 /><h3 />

Hey there!

2x + 10 = 20

x = 5 so 2 x 5 = 10 + 10 = 20

Therefore, x = 5

Hope this helps you!

God bless ❤️

Solve this system of equations: -8x+4y=16; y=5x+1 *

SCORPION-xisa [38]

Answer:

x=1, y=6. (1, 6).

Step-by-step explanation:

-8x+4y=16

y=5x+1

----------------

-8x+4(5x+1)=16

-8x+20x+4=16

12x+4=16

12x=16-4

12x=12

x=12/12

x=1

y=5(1)+1=5+1=6

F(x)=e*1/x<br>Calculate f'(x)

Murljashka [212]

Answer:

$\huge\boxed{f'(x)=-\dfrac{e^\frac{1}{x}}{x^2}}$

Step-by-step explanation:

$(e^x)'=e^x\\\\\bigg[f\bigg(g(x)\bigg)\bigg]'=f'\bigg(g(x)\bigg)\cdot g'(x)\\\\\left(\dfrac{1}{x}\right)'=-\dfrac{1}{x^2}\\\\====================$

$f(x)=e^\frac{1}{x}=\left(e^\frac{1}{x}\right)'\cdot\left(\dfrac{1}{x}\right)'=e^\frac{1}{x}\cdot\left(-\dfrac{1}{x^2}\right)=-\dfrac{e^\frac{1}{x}}{x^2}$

Which parent functions have an intercept at (0,0)Choose all that are correct.

inessss [21]

Answer:

Linear, Quadratic, Radical, Absolute Value, Cubic, Cube Root

Step-by-step explanation:

To find:

Which functions have an intercept at (0, 0).

That means, when we put a value $x=0$ in the $y =f(x)$ , value of $y=0$ .

Let us discuss each <em>parent</em> function one by one:

1. Linear:

$y = x$

When we put x = 0, y = 0

Therefore, it has intercept at (0, 0).

2. Quadratic:

$y = x^2$

When we put x = 0, y = 0

Therefore, it has intercept at (0, 0).

3. Radical:

$y = \sqrt x$

When we put x = 0, y = 0

Therefore, it has intercept at (0, 0).

4. Absolute Value:

$y = |x|$

When we put x = 0, y = 0

Therefore, it has intercept at (0, 0).

5. Rational:

$y = \dfrac{1}{x}$

When we put $x = 0\Rightarrow y \rightarrow \infty$

Therefore, it does not have intercept at (0, 0).

6. Exponential:

$y = b^x$

b is any base

When we put $x = 0\Rightarrow y =1$

Therefore, it does not have intercept at (0, 0).

7. Logarithmic:

$y = logx$

When we put $x = 0 \Rightarrow y\rightarrow$ Not defined

Therefore, it does not have intercept at (0, 0).

8. Cubic:

$y = x^3$

When we put $x = 0\Rightarrow y =0$

Therefore, it has intercept at (0, 0).

9. Cube Root:

$y = \sqrt[3]x$

When we put $x = 0\Rightarrow y =0$

Therefore, it has intercept at (0, 0).

Solve the compind inequality -14<-6x-2(less than or equal to)22

dangina [55]

First you need to add 2 to every part of the equation. So -14+2, -2+2, and 22+2. After that you need to divide every part by 6, -12/6, 6/6, 24/6 which gives you the answer; -2
