You have two equations.
since the second is already isolated, sub in x-4 for every y in equation 1 so that 
x^{2} - 4 [(x-4)^{2}] =16

expand, collect like terms, factor to find x, then plug x value back into original equation to find y

Noah and Lin are each trying to solve the equation x² - 6x + 10 = 0. They know that the solutions to x² = - 1 are i and -i, but
Leviafan [203]

Answer:

Solving the equation x^2 - 6x + 10 = 0 we get x=3+i \ , \ x=3-i

Step-by-step explanation:

Noah's step to solve the equation x^2 - 6x + 10 = 0 are:

x^2 - 6x + 10 = 0\\x^2 - 6x = -10\\x^2 - 6x + 9 = -10 + 9\\(x-3)^2 = -1

The next step is to take square root on both sides because: \sqrt{x^2}=x

\sqrt{(x-3)^2}=\sqrt{-1}  \\x-3=\pm\sqrt{-1} \\x=\pm(\sqrt{-1})+3 \\

Now, we know that: \sqrt{-1}=i

x=\pm(i)+3\\x=3+i \ , \ x=3-i

So, Solving the equation x^2 - 6x + 10 = 0 we get x=3+i \ , \ x=3-i

4 times the measure of the complement of an angle is equal to 2/3he measure of the original angle's supplement. what is the meas
Andrej [43]
Let x be the angle
Complement of x is (90 degrees-x)
Supplement of x is (180 degrees-x)

4•(90-x)= 2/3(180-x)
3•4(90-x)=2(180-x)
1080-12x=360-2x
1080-360=12x-2x
720=10x
720/10= x
So x = 72 degrees

Can someone explain step by step how to do this and how to get the numbers please? HELP HELP HELP!!
Alexxandr [17]
A = 113.1
so the formula for the area of a circle is
A = pi x r^2
-pi is 3.14(rounded)

-r stands for the radius of the circle which is half the diameter so for this circle your r or radius is 6 and the radius is just squared

so when you plug the numbers in the formula it is
A = 3.14 x 6^2(squared)

A = 3.14 x 36

A = 113.1
