How to factorise this?!
4x-14xy

Answers

Find the highest common factor, which is 2X, therefore, this goes outside of the bracket. So inside goes 4x/2x= 2 & 14xy/2x= 7y2x(2-7y)When you multiply out of the brackets, everything should be equal

Take a factor of x out of the equation:
2x(2-7y)

What is the graph of 3x + 5y = –15?

Answers

Answer:

Graph is option A

Step-by-step explanation:

3x + 5y = –15

To graph the equation , we need to get y alone

$3x + 5y = –15$

Subtract 3x on both sides

$5y = -3x–15$

Divide whole equation by 5

$y=-(3x)/(5) -3$

To graph this equation , we need to make a table

Plug in some number for x and find out y

x $y=-(3x)/(5) -3$

0 -3

-5 0

Two points on the graph is (-5,0) and (0,-3)

Graph is option A

For what values of r does the function y = erx satisfy the differential equation y'' + 5y' + 6y = 0?

Answers

Answer:

$\huge\boxed{r=-2,-3}$

Step-by-step explanation:

To solve for the values of $r$ where the differentialequation $y'' + 5y' + 6y = 0$ is satisfied by the function $y=e^(rx)$ , we first need to find the first and second derivatives of $y$ with respect to $x$ , treating $r$ as a constant.

$\left[\frac{}{}y\frac{}{}\right]'=\left[\frac{}{}e^(rx)\frac{}{}\right]'$

↓ applying the chain rule to the right side: $\displaystyle \left[\frac{}{}f(x)^a\frac{}{}\right]' = a \cdot f(x)^((a\, -\, 1)) \cdot f'(x)$ where $f(x) = e^x$ and $a = r$

$y'=r\cdot e^((rx \,-\, 1)) \cdot e^x$

↓ simplifying using the exponentbaseproduct rule: $x^a \cdot x^b = x^((a \, +\, b))$

$y' = re^(\left[(rx \,-\, 1)\, +\, 1\right])$

$\boxed{y' = re^(rx)} \ \ \leftarrow \ \ \text{first derivative}$

─────────────────────────────────

↓ taking the derivative of $y$ with respect to $x$

$y'' = \left[\frac{}{} re^(rx)\frac{}{}\right]'$

↓ takingout the constant ( $r$ ) on the right side

$y'' = r\left[\frac{}{} e^(rx)\frac{}{}\right]'$

↓ simplifying by substituting in the first derivative

$y'' = r \cdot y'$

$y'' = r \cdot re^(rx)$

$\boxed{y'' = r^2e^(rx)} \ \ \leftarrow \ \ \text{second derivative}$

Now, we can plug these derivative expressions into the differential equation and solvefor r.

$y'' + 5y' + 6y = 0$

↓ pluggingin the derivativeexpressions (think of $y$ as the zeroth derivative of itself)

$r^2e^(rx) + 5(re^(rx)) + 6(e^(rx)) = 0$

↓ factoringout $e^(rx)$ from the left side

$e^(rx)(r^2 + 5r + 6) = 0$

↓ factoring the second-degree polynomial factor

$e^(rx)(r + 2)(r + 3) = 0$

↓ splitting into 3 equations using the zero product property: $\text{If } ABC = 0,\text{ then } A=0\text{ or }B=0\text{ or }C=0.$

First Equation

$e^(rx)=0$

↓ taking the natural log of both sides

$rx = \ln(0)$

$\implies \text{un}\text{de}\text{fi}\text{ne}\text{d}$

Second Equation

$r+2=0$

↓ subtracting 2 from both sides

$\huge\boxed{r=-2}$

Third Equation

$r+3=0$

↓ subtracting 3 from both sides

$\huge\boxed{r=-3}$

How to solve equation x/3-4=10?

Answers

If you would like to solve the equation 2x / 5 + 1 = 7, you can do this using the following steps:

2x / 5 + 1 = 7
2x + 5 = 5 * 7
2x = 35 - 5
2x = 30
x = 15

If you would like to solve the equation x/3 - 4 = 10, you can do this using the following steps:

x/3 - 4 = 10
x/3 = 10 + 4
x/3 = 14
x = 14 * 3 = 42
