What is the slope of a line that passes through the points (-2, 4) and (-6, 12)?

SOVA2 [1]

We can use the formula y2-y1/x2-x1 to find the answer. Therefore, we have: 12-4/ -6-(-2). That gets us 8/-6+2 = 8/-4= -1/2. The answer is 3.

a silkworm winds its cocoon out of one long silk fiber. to make silk thread, 3 to 10 of these silk fibers are unwound from their

Scorpion4ik [409]

Answer:

Possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.

Step-by-step explanation:

Let the length of the silk fiber = x yards.

Let the number of silk fibres = a.

It is given that the silk fibers between 3 to 10 yards are combined to form a silk thread of 300 yards.

So, we get the equation,

$ax=300$ , where $3\leq a\leq 10$

i.e. $x=\frac{300}{a}$ , $3\leq a\leq 10$

So, the possible values of 'a' are 3, 4, 5, 6 an 10.

Thus, the possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.

Type an equation for the following pattern

umka2103 [35]

For the given table, the difference between two consecutive y terms are

$4-3=5-4=6-5=7-6=1$

It means the difference is constant. So the given function is in arithmetic progression.

And to find the equation, representing the given series, we will use the formula for the nth term of arithmetic series, which is

$a_{n}= a+ (n-1)d$

Here,

$a_{n} =y, n=x, and \ d \ for \ the \ common \ difference.$

So we will get

$y= 3+(x-1)(1)
\\
y = 3 + x-1
\\
y= x +2$

svet-max [94.6K]

Answer:

Hi, There!

Your Answer is $\frac{6}{12} ~or~\frac{1}{2}$

Step-by-step explanation:

$\frac{3}{4} ~x~\frac{2}{3} = \frac{3 ~x~2}{4~x~3}$

Which Equals

$\frac{6}{12}$

Now if you dived the numerator and denominator by 6 you Get...

$\frac{1}{2}$

Therefore, I hope this helps!
