Solve with quadratic formula.<br> 4k^2- 20 = k
zvonat [6]

Answer: k= \frac{1+\sqrt{321} }{8} , \frac{1-\sqrt{321} }{8}

Step-by-step explanation:

Move all terms to one side.

4^{2} -20-k=0

Use the Quadratic Formula.

k=\frac{1+\sqrt{321} }{8} , k=\frac{1-\sqrt{321} }{8}

How do you work out this equation
Gnom [1K]

Answer:

x is equal to negative one, and y is equal to negative four.

Step-by-step explanation:

You can do this by solving one of the equations by either x or y, then substituting it into the other.  Let's solve the second one for y:

2y = 3x - 5\\y = \frac{3x - 5}{2}

Now we'll substitute that into the first equation:

9x - 2y = -1\\9x - 2(\frac{3x - 5}{2}) = -1\\9x - 3x + 5 = -1\\6x + 5 = -1\\6x = -6\\x = -1

So we now know that x is equal to -1.  We can simply substitute that into one of the original equations to find y:

2y = 3x - 5\\2y = 3(-1) - 5\\2y = -3 - 5\\2y = -8\\y = -4

We now know that x is equal to -1, and y is equal to -4.  We can also check our answer by plugging that -4 into the other equation, and see if we still get -1:

9x - 2y = -1\\9x - 2(-4) = -1\\9x + 8 = -1\\9x = -1 - 8\\9x = -9\\x = -1

So we know that our answer is correct.
