Answer:

to find slope we use the following methods

Step-by-step explanation:

given

X1 -2

X2= -4

Y1= 2

Y2= -4

slope=y2-Y1 ÷X2-X1

= -4-2÷ -4-(-2)

=-6 ÷-4+2

= -6÷-2

= 3

slop of (-2,2) (-4,-4) = 3

Determine the nth term for each of the following sequences:16,15,14,13,12,..
Vladimir79 [104]
F(n) = 1st term - common difference (n - 1)

The operation is subtraction because the sequence is decreasing.

n = number of the term you are looking for
1st term = 1st number in the sequence, in this case, 16
common difference = difference between one number to the next

f(n) = 16 - 1(n-1)

Assuming we are looking for the 5th term.
f(5) = 16 - 1(5-1)
       = 16 - 1(4)
       = 16 - 4
       = 12     * as you can see, 12 is the 5th term of the sequence.

If you are looking for the equivalent of the nth term, simply substitute n by the number you are looking for and solve the equation.

In the trapezoid below, x = [ ? ].<br> 2x+6<br> I<br> 5x=20<br> 4r+2
KonstantinChe [14]

Answer:

x = 12

Step-by-step explanation:

To get the value of x, we use the mid-segment theorem of trapezoid

The theorem is that the mid-segment is half the sum of the other two segments

We have this as

;

5x - 20 = 1/2(2x + 6 + 4x + 2)

2(5x-20) = 6x + 8

5x -20 = 3x + 4

5x -3x = 4 + 20

2x = 24

x = 24/2

x = 12

Line j passes through points (10, 10) and (1, 3). Line k is parallel to line j. What is the slope of line k?
SOVA2 [1]

Answer:

= (10-3) ÷ (10-1) = 7 ÷9 = 7/9

Step-by-step explanation:

As they are parallel, their slopes are the same. So if we find slope of line j we find slope of line k when we have two points of one line like (x1 , y1) and (x2 , y2) the slope of that line is (y2-y1) ÷ (x2-x1)

Find the values of x, y, and λ that satisfy the system of equations. Such systems arise in certain problems of calculus, and λ i
Nimfa-mama [501]

Answer:

x=4, y=4, λ=-16

Step-by-step explanation:

We have this 3x3 system of linear equations:

4x+λ=0

4y+λ=0

x+y=8

So, let's rewrite the system in its augmented matrix form

\left[\begin{array}{cccc}4&0&1&0\\0&4&1&0\\1&1&0&8\end{array}\right]

Let´s apply row reduction process to  its associated augmented matrix:

Swap R1 and R3

\left[\begin{array}{cccc}1&1&0&8\\0&4&1&0\\4&0&1&0\end{array}\right]

R3-4R1

\left[\begin{array}{cccc}1&1&0&8\\0&4&1&0\\0&-4&1&-32\end{array}\right]

R3+R2

\left[\begin{array}{cccc}1&1&0&8\\0&4&1&0\\0&0&2&-32\end{array}\right]

Now we have a simplified system:

x+y+0=0

0+4y+λ=0

0+0+2λ=-32

Solving for λ, x, and y

λ=-16

x=4

y=4
