solve the following equations

63= 12x -21

Answers

Answer 1
x=7 i hope this helped
Answer 2

Answer:

X=7

take the -21 to the other side of the equation, when you do this it goes from a negative to a positive so we now have 63+21=12x

if we add 63 and 12 we get 84 decide by 12 because we have 12x and we get 7

p/q=r/s (solve for q)

Answers

Answer:

q=pr/s

Step-by-step explanation:

p/q=r/s multiplication is the inverse of division so they cancel out. and you have to do the same thing to both sides so multiply both sides by "q" it cancels out on the left and stays on the right leaving you with

q=pr/s

Answers

Answer:

y = 8x + 67

Step-by-step explanation:

The equation of a line in slop- intercept form is

y = mx + c

Given

y - 3 = 8(x + 8) ← distribute parenthesis

y - 3 = 8x + 64 ( add 3 to both sides )

y = 8x + 67 ← in slope- intercept form

Multiply 9x and 18 with -1/3

-1/3 times 9x is -3x

-1/3 times 18 is -6

Answer: (x+2)*(x-4)*(x+21) = 0 has "many" solutions

Step-by-step explanation: (x+2) = 0 only has one solution.  

(x+2)*(x-4) = 0 has two solutions, -2 and 4

(x+2)*(x-4)*(x+21) = 0 has three solutions, -2, 4, and -21, etc

If "many" means more than three, then add another (x+XX) term.  A quadratic equation generally has two solutions.

I need help checking the answer to it.

I think it's 10.583005244

I'm not sure and i need all teh help i can get, thanks

Answers

Answer:

Take the square root of a number that is not a perfect square. None of the numbers are perfect squares. After you do that you can do any closed operation you want with the resulting irrational and the two other rationals and you will end up with an irrational.

8*24*√5 is an example.

8+24+√5 is another

5*√8 + 24 is another.

If you take the cube root of any number that isn't a perfect cube you get an irrational, so you could take the cube root of 5 or 24 instead of the square root and do the same thing.
