Answer:

x + 3y = 30

Step-by-step explanation:

We are given that a line contains the points (12,6) and (-3,11)​.

We want to write the equation of this line in standard form.

Standard form is written as ax+by=c, where a, b, and c are free integer coefficients, however a and b cannot be 0, and a cannot be negative.

Regardless, before we write an equation in slope-intercept form, we must first write the equation in a different form, such as slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y-intercept.

So first, let's find the slope of the line.
The slope (m) can be found using the formula \frac{y_2-y_1}{x_2-x_1}, where (x_1, y_1) and (x_2, y_2) are points.

Even though we already have 2 points, let's label their values to avoid any confusion and mistakes when calculating.

x_1=12\\y_1=6\\x_2=-3\\y_2=11

Now substitute these values into the formula.

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{11-6}{-3-12}

Subtract

m=\frac{5}{-15}

Simplify

m=-\frac{1}{3}

The slope is -1/3

Here is the equation of the line so far in slope-intercept form:

y=-\frac{1}{3} x + b

We need to solve for b.

As the equation passes through (12,6) and (-3,11)​, we can use either one to help solve for b.

Taking (12, 6) for example:

6=-\frac{1}{3}(12)  + b

Multiply

6=-\frac{12}{3}  + b

Divide

6 = -4 + b

Add 4 to both sides.

10 = b

Substitute 10 as b in the equation.

y = -\frac{1}{3} x + 10

Here is the equation in slope-intercept form, but remember, we want it in standard form.

In standard form, the values of both x and y are on the same side, so let's add -1/3x to both sides.

\frac{1}{3} x + y = 10

Remember that a (the coefficient in front of x) has to be an integer, 1/3 is not an integer.

So, let's multiply both sides by 3 to clear the fraction.

3(\frac{1}{3} x + y) = 3(10)
Multiply.

<u>x + 3y = 30</u>

<u></u>

Use Euler’s method with two steps to estimate y(1) if y(x) is the solution to dy dx = x + y, y(0) = 1. Write your answer in the
tresset_1 [31]

Answer:

1.5

Step-by-step explanation:

The Euler's method is a common approximation method for the solution of differential equations. It can be used to obtain an approximate value of a given function. The Euler's formula is:

y_{n} = y_{n-1} + hF(_{x_{n-1},y_{n-1}})

Therefore, n =1 will give:

y_{1} = y_{0} + hF(x_{0},y_{0})

h is the step size and it is equivalent to \frac{x_{1}-x_{2}}{2} = \frac{1-0}{2}=\frac{1}{2}

F(x_{0},y_{0}) = x_{0} + y_{0} = 0 + 1 = 1

y_{1} = 1 + (0.5)(0+1) = 1 + (0.5)(1) = 1 + 0.5 = 1.5

Y-24=-7 i also need to be able to show my work and make sure its correct
german

All you have to do is add 24 to both sides and you will get y.  You add 24 so that it will cancel from one side but be added to the other.  


The answer is y=17.


Hope this helps!
