8(12 - k) = 3(k + 21)
Please help! I am confused with some signs.​

Answers

Answer 1

Answer: k = 3

Step-by-step explanation:

U first expand

96 - 8k = 3k + 63

Then u add 8k from both sides

96 = 3k + 63 + 8k

then u simplify

3k + 63 + 8k to 11k + 63

then u subtract 63 from both sides

96 = 11k + 63

Then u simplify 96 - 63 to 33

33 = 11k

Then u divide both sides by 11

33/11 = k

then u simplify 33/11 to 3

3 = k

and last u switch the sides

k = 3

What is the distance between two points ( p,q) and (x,y)?

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

 [tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

Substituting the values of the coordinates in the distance formula;

 D = [tex]\sqrt{(1-1)^{2}+(18+4)^{2} }[/tex]

     =[tex]\sqrt{(0)^{2} + (22)^{2} }[/tex]

     = [tex]\sqrt[n]{484}[/tex]

      = 22

So, 22 units is the right answer.

Answer=

x=(-2),y=(-4)

and in components form,

(-2,-4)

Step-by-step explanation:

equation1 (-2x+2y=-4)

equation2 (3x+3y=-18)

(times equation 1 by 3 and times equation 2 by 2, to make the y values equal to each other)

E1 (-6x+6y=-12)

E2 (6x+6y=-36)

(subtract both equations from each other)

-6x+6y=-12

-

6x+6y=-36

=(-12x=24)

so, x=24÷-12=-2

(then we sub the value of x into one of the equations- the new one or the old one)

3x+3y=-18

(3×-2)+3y=-18

3y=-18+6=-12

y=-12÷3=-4

Answers

Yes she will break the school record if she continues to score at that rate. You divide 60 / 4 since there are 60 minutes in a full game. That gives you 15. Then you multiply that answer by 9 because she scores 9 points each of those 4 minutes. That will get her to score 135 points by the end of the game
