Answer:

The correct option is B.

Step-by-step explanation:

The given equation is

$y=-3x$ .... (1)

The slope intercept form of a line is

$y=mx+b$ .... (2)

Where, m is slope and b is y-intercept.

From (1) and (2), we get

$m=-3,b=0$

The slope of the line is -3.

Therefore the correct option is B.

The answer to this question would be B, -3. The reason for this is because when you have an equation in slope intercept form, it would be y = mx + b. In this case your b is equal to 0 so you have only y = mx. The variable m represents the slope, which is in this case, equal to -3. Hope this helps. Please rate, leave a thanks, and mark a brainiest answer. (Not necessarily mine). Thanks, it really helps! :D

Likurg_2 [28]

Answer:

$Area=24x^2-34x-45$

Step-by-step explanation:

Length and width of the yard are $(6x+5)$ and $(4x-9)$ .

$Area=length\times width\\\\Area=(6x+5)\times (4x-9)\\\\Area=24x^2+20x-54x-45\\\\Area=24x^2-34x-45$

Solve the equation. y 3 = –y 9 y = 1 y = 3 y = 6 y = 9

GaryK [48]

The solution of the equation is y = 3.

<h3>What is the linear equation?</h3>

An equation between two variables that gives a straight line when plotted on a graph.

The solution to the equation is;

$\rm y + 3 = -y + 9\\\\y+y=9-3\\\\2y=6\\\\y=\dfrac{6}{2}\\\\y=3$

Hence, the solution of the equation is y = 3.

What is the area of a regular hexagon if a side is 30

sergij07 [2.7K]

<h3>Answer:</h3>

$1350\sqrt{3}$ square units (approximately 2338.26859)

<h3>Step-by-step explanation:</h3>

The formula for finding the area of a regular hexagon when you know its side length is $A=\frac{3\sqrt{3}*s^2}{2}$ , where $A$ is the area and $s$ is the side length.

Substitute in the side length. $A=\frac{3\sqrt{3}*30^2}{2}$
Simplify the exponent. $A=\frac{3\sqrt{3}*900}{2}$
Multiply. $A=\frac{2700\sqrt{3}}{2}$
Divide. $A=1350\sqrt{3}$

$1350\sqrt{3}$ is as simple as the solution can get without estimating, but you can estimate with a calculator to find that it is approximately 2338.26859.
