How to find slope when giving two equations that equal each other?

9966 [12]

slope formula.:

m = (y_2 - y_1) / (x_2 - x_1)

so you just need two points from whatever function you have

Or if you already have the function formula, then just the number of the first term (if your function is this: y=ax^2 + bx + c then the a is the slope)

Hope this helps!

If 3 cot theta= 2, find the value of 2sin theta -3cos theta /2sin theta +3cos theta

sergeinik [125]

Answer:

Step-by-step explanation:

Using the trigonometric identity

cotx = $\frac{cosx}{sinx}$

Given

3cotθ = 2 , then

3 $\frac{coso}{sino}$ = 2 ( multiply both sides by sinθ )

3cosθ = 2sinθ ( subtract 3cosθ from both sides )

2sinθ - 3cosθ = 0

Thus

$\frac{2sin0-3cos0}{2sin0+3cos0}$

= $\frac{0}{2sin0+3cos0}$

= 0

Simplify: |x−y| if x is less than y

blondinia [14]

Answer:

y-x

Step-by-step explanation:

I assumed you meant that you wanted me to rewrite the expression without the absolute value signs. Since the absolute value of a number will be the same whichever way you place the numbers, you can rewrite |x-y| as y-x, as x is less than y.

Write an augmented matrix of each system. Then, solve each system using matrix notation. Describe the solution set in vector not

Naddik [55]

Answer:

The answer is below

Step-by-step explanation:

Given the system of equations:

x + y + 2z = 9

2x + 4y - 3z = 1

3x + 6y - 5z = 0

This system of equation can be solved using matrix. This done by first representing the equations as matrix and then solving:

The matrix form is:

$\left[\begin{array}{ccc}1&1&2\\2&4&-3\\3&6&-5\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}9\\1\\0\end{array}\right] \\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}1&1&2\\2&4&-3\\3&6&-5\end{array}\right] ^{-1} \left[\begin{array}{c}9\\1\\0\end{array}\right] \\\\\\$

$\left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}2&-17&11\\-1&11&-7\\0&3&-2\end{array}\right] \left[\begin{array}{c}9\\1\\0\end{array}\right] \\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{c}1\\2\\3\end{array}\right]$
