Answer:

K= -2

Step-by-step explanation:

20-6+4*k-(2-2*k)=0

Pull out like factors

12 + 6k = 6 • (k + 2)

Solve: 6 = 0 which ends that this equation has no solution because a non zero constant never equals zero

Solve: K+2 = 0

now substract 2 from both sides of the equation: K= -2

Hope I explained myself :/

Hope it helps :)

Noah has a total of 47 video games he only buys action games in sports games he has 21 warehousing in the sports games how many

kicyunya [14]

Question is not proper;Proper question is given below;

Noah has a total of 47 video games. he only buys action games and sports games. He has 21 more action games than sports games. how many action games, a, and sports games, s, does he own?

Answer:

Noah has 34 action games and 13 sports games.

Step-by-step explanation:

Given:

Total number of games he has = 47

Let the number of action games be 'a'.

Let the number of sports game be 's'.

So we can say that;

Total number of games he has is equal to sum of the number of action games and the number of sports games.

framing in equation form we get;

$a+s = 47 \ \ \ \ \ eqaution \ 1$

Also Given:

He has 21 more action games than sports games.

so we can say that;

$a=s+21 \ \ \ equation\ 2$

Now Substituting equation 2 in equation 1 we get;

$a+s=47\\\\s+21+s=47\\\\2s+21=47$

Subtracting both side by 21 we get;

$2s+21-21=47-21\\\\2s = 26$

Dividing both side by 2 we get;

$\frac{2s}{2}=\frac{26}{2}\\\\s=13$

Now Substituting the value of 's' in equation 2 we get;

$a=s+21=13+21=34$

Hence Noah has 34 action games and 13 sports games.

A is the right option! Because 0.40 should be in second equation with the x to represent the number of stamps multiply by 40 cents.

What is the equation of the given line in the point-slope form

Genrish500 [490]

First using the given two points we can find the slope (m) of the line

$Slope = m = \frac{Rise}{Run} \\ \\ 
m= \frac{4-1}{3-0} \\ \\ 
m=1$

Thus the slope of given line is 1.

Using slope and a point (0,1) we can write the equation in point slope form as

y - 1= 1(x-0)
y - 1 = x

The above equation is the point-slope form of the equation.
