Answer: M= slope

M= -4/6

Step-by-step explanation:

M= change in y over the change in x so you would do -3 -1 over 4 -(-2) which would give you the slope of -4/6

Answer:

- 2/3

Step-by-step explanation:

Slope = y2 - y1/x2 - x1

Given

x1 = 4

y1 = -3

x2 = -2

y2 = 1

Slope = 1 - (-3) /-2 -4

= 1 + 3 /-2 -4

= 4/-6

= 2/-3

= - 2/3

Can someone please help me?!!!!

My name is Ann [436]

Firstly let’s assume she is correct and use an equal sign:
1/2(12x + 24) = 3(2x + 4)

Now simplify both sides:
1/2 • 12x = 6x
1/2 • 24 = 12
6x + 12

3 • 2x = 6x
3 • 4 = 12
6x + 12

And:
6x + 12 = 6x + 12
Therefore they are equivalent, she is correct.

Solve for x. NEED HELP

TiliK225 [7]

Answer:

22.470

Step-by-step explanation:

In this example you have to use the trigonometric function sine which is defined as $sin(\theta) = \frac{opposite}{hypotenuse}$

Plug in known values:

$sin(64) = \frac{x}{25}$

Multiply both sides by 25

$sin(64) * 25 = x$

Approximate sin(64) using a calculator:

$0.89879 * 25 = x$

Simplify

$22.470 \approx x$

Find all solutions <br> 36x²+12x=0

FromTheMoon [43]

Answer:

x = -1/3 or 0

Step-by-step explanation:

Given equation:

$36x^{2} + 12x = 0$

We can factor 12x on the L.H.S since 12x is divisible by 36x² and 12x.

$\implies 36x^{2} + 12x = 0$

$\implies 12x(3x + 1) = 0$

This can lead to two solutions. I have listed them below!

<h2>Solution 1:</h2>

Divide 12x on both sides to open the parentheses.

$\implies 12x(3x + 1) = 0$

$\implies \dfrac{12x(3x + 1)}{12} = \dfrac{0}{12}$

<em>Note: zero divided by any non-zero number is 0.</em>

$\implies \dfrac{12x(3x + 1)}{12} = \dfrac{0}{12}$

$\implies 3x + 1 = 0$

Isolate 3x on one side of the equation.

$\implies 3x + 1 = 0$

$\implies 3x = 0 - 1$

$\implies 3x = -1$

Divide 3 both sides to determine the value of x.

$\implies 3x = -1$

$\implies \dfrac{3x}{3} = \dfrac{-1}{3}$

$\implies \boxed{x = \dfrac{-1}{3}}$

<h2>Solution 2:</h2>

Divide (3x + 1) on both sides to isolate 12x.

$\implies 12x(3x + 1) = 0$

$\implies \dfrac{12x(3x + 1)}{(3x + 1)} = \dfrac{0}{(3x + 1)}$

<em>Note: zero divided by any non-zero number is 0.</em>

$\implies \dfrac{12x(3x + 1)}{(3x + 1)} = \dfrac{0}{(3x + 1)}$

$\implies 12x = 0$

Divide 12 both sides to determine the value of x.

$\implies 12x = 0$

$\implies \dfrac{12x}{12} = \dfrac{0}{12}$

$\implies \boxed{x = 0}$

Therefore, the solutions for x are -1/3 or 0.
