Answer:

x = 2

Step-by-step explanation:

We can make an equation that meets the requirements stated.

Decreased signifies subtraction, so 12 will reduce the value after it. A number can be any letter you'd like, but I'll stick to x. Since 2 is multiplying <em>that</em> number, we can make 2 the coefficient. Finally, set it equal to 8.

12 - 2x = 8 Subtract 12 from both sides of the equation.

-2x = -4 Divide by -2 on both sides of the equation.

x = 2

Need brief explanation about why false is correct
anyanavicka [17]

<u>We are given the equation:</u>

(a + b)! = a! + b!

<u>Testing the given equation</u>

In order to test it, we will let: a = 2 and b = 3

So, we can rewrite the equation as:

(2+3)! = 2! + 3!

5! = 2! + 3!

<em>We know that (5! = 120) , (2! = 2) and (3! = 6):</em>

120 = 2 + 6

We can see that LHS ≠ RHS,

So, we can say that the given equation is incorrect

Consider the following linear equation.y = -1-Step 1 of 2: Determine the slope and the y-intercept (entered as an ordered pair)
Dmitriy789 [7]

Recall that a slope-intercept form of a linear equation is

\begin{gathered} y=mx+b \\ \text{where} \\ m\text{ is the slope} \\ b\text{ is the y-intercept} \end{gathered}

Rearrange the given so that it follows that slope intercept form

\begin{gathered} y=-1-\frac{2}{5}x\Longrightarrow y=-\frac{2}{5}x-1 \\  \\ \text{Now that it is in the slope intercept form} \\ y=-\frac{2}{5}x-1 \\ \text{we can determine that the slope is } \\ m=-\frac{2}{5} \\ \text{and the y-intercept is} \\ b=-1 \end{gathered}

The y-intercept is the value for which the linear function crosses the y-axis, this is when the value of x is equal to zero. The ordered pair therefore of the y-intercept is (0,-1).

Three schools are located at points A, B, and C. The school district wants to locate its new stadium at a location that will be
dangina [55]

I have attached the image showing the location of the three schools.

Answer:

Should be built at the centroid of the triangle formed by points A, B and C.

Step-by-step explanation:

From the attached image, we see that if we join the 3 points by a straight line, they will form a triangle.

Now, to get a location that will be roughly the same distance from all 3 schools, it means a point that is equal to each of 3 vertex of the triangle.

The point that is equal to each vertex of a triangle is known as "Centroid".

Now, to find this centroid, we will add up the (x, y) coordinates of the 3 vertex and divide by 3.

For example;let's assume ;A has a coordinate of (x1, y1) ; B has a coordinate of (x2, y2) ; C has a coordinate of (x3, y3).

The coordinates of the centroid will be;

[(x1 + x2 + x3)/3], [(y1 + y2 + y3)/3]

What are the excluded values for m+4m+2=8m+2?
aliina [53]
That equation is the same as 3m=0, only m=0 works. Do you think they want you to say, all numbers but zero are excluded? Or is the equation different?
