39. State the equation for the line described below.
devlian [24]

Answer:

Step-by-step explanation:

39). y = -\frac{7}{8} x + 3

40). m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

y - y_{1} = m( x - x_{1} )

(- 7, 5)

( - 12, 4)

m = ( 4 - 5 ) / ( - 12 + 7) = 1/5

y - 5 = (1/5)(x + 7) ⇒ y = \frac{1}{5} x + 6.4

Ile kilogramów solanki 6-procentowej i ile kilogramów 9-procentowej należy zmieszać, aby otrzymać 9 kilogramów solanki 8-procent
viktelen [127]

Answer:  solanka 6-procentowa=3 kg

solanka 9-procentowa = 6 kg

Step-by-step explanation:

Let solanka 6-procentowa=x kg

Let solanka 9-procentowa = y kg

So x+y=9  

=> x=9-y                           (1)

6%=0.06      9%=0.09    8%=0.08

So pure salt is 0.06*x +0.09*y= 9*0.08   (2)

Lets put 9-y instead x in (2)

0.06*(9-y) +0.09*y=0.72

0.54-0.06*y +0.09*y=0.72

0.03*y=0.18

y=6kg  =>  x=9-y => x=9-6=3 kg

PLZ EXPLAIN AND I'LL GIVE BRAINLY!!!!

Hello there!

Given the sequence:

\displaystyle \large{ 1, - 3,9, - 27,...}

The question reveals it to be geometric sequence since it has common ratio.

<u>G</u><u>e</u><u>o</u><u>m</u><u>e</u><u>t</u><u>r</u><u>i</u><u>c</u><u> </u><u>S</u><u>e</u><u>q</u><u>u</u><u>e</u><u>n</u><u>c</u><u>e</u> / <u>R</u><u>a</u><u>t</u><u>i</u><u>o</u><u> </u><u>F</u><u>o</u><u>r</u><u>m</u><u>u</u><u>l</u><u>a</u>

<u>\displaystyle \large{r =  \frac{a_{n + 1}}{a_n} }</u>

Define 'r' as common ratio.

First, let's check the common ratio by using the formula above.

<u>R</u><u>a</u><u>t</u><u>i</u><u>o</u><u> </u><u>C</u><u>h</u><u>e</u><u>c</u><u>k</u>

\displaystyle \large{r =  \frac{ - 3}{1} \longrightarrow  - 3 } \\  \displaystyle \large{r =  \frac{ 9}{ - 3} \longrightarrow  - 3 } \\  \displaystyle \large{r =  \frac{ - 27}{9} \longrightarrow  - 3 }

Therefore, the common ratio or r-value is -3.

To find the 7th term of sequence, you can by using the General Geometric Terms.

<u>G</u><u>e</u><u>n</u><u>e</u><u>r</u><u>a</u><u>l</u><u> </u><u>T</u><u>e</u><u>r</u><u>m</u><u> </u><u>o</u><u>f</u><u> </u><u>G</u><u>e</u><u>o</u><u>m</u><u>e</u><u>t</u><u>r</u><u>i</u><u>c</u>

\displaystyle \large{a_n = a_1 {r}^{n - 1} }

a1 is defined as the first term of sequence.

r is common ratio.

n is the term.

Since we want to find 7th term:

  • a1 = 1
  • r = -3
  • n = 7

\displaystyle \large{a_7 =1{( - 3)}^{7 - 1} } \\  \displaystyle \large{a_7 =1{( - 3)}^{6} } \\  \displaystyle \large{a_7 =729 }

Therefore, the 7th term of this sequence is 729.

Let me know if you have any questions!
