What is the value of a in the equation a = 2 + 3a + 10?

xxTIMURxx [149]

Answer:

a= -6

Step-by-step explanation:

Given

a=2+3a+10

In order to find the value of a, we have to isolate a on a single side of the equation

So,

subtracting 3a from both sides

a-3a = 2+10+3a-3a

=>a-3a=12

=> -2a = 12

Dividing both sides by -2

=> -2a/-2 = 12/-2

=> a = -6

The value of a in the given equation is -6 ..

Answer:

The slope of the line is -1

Step-by-step explanation:

Slope of a Line

Suppose we know a given line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated as follows:

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

From the table in the image, we select the points (1,4) (3,2). The slope is:

$\displaystyle m=\frac{2-4}{3-1}=\frac{-2}{2}=-1$

Now select two other points like (5,0) (7,-2)

$\displaystyle m=\frac{-2-0}{7-5}=\frac{-2}{2}=-1$

Following the same procedure with any other pair of points, we'll get the very same result:

The slope of the line is -1

olasank [31]

Answer:

(3.5, 4)

Step-by-step explanation:

add and then divide (x1+x2 / 2, y1 + y2 / 2) so [(1+6)/2, (3+5)/2], so (3.5, 4)
