Answer: the system has no solution.
Step-by-step explanation:
\displaystyle\\
\left \{ {{x^2y=16\ \ \ \ \ (1)} \atop {x^2+4y+16=0\ \ \ \ \ (2)}} \right. .\\
Multiply\ both\ sides\ of\ the\ equation\ (2)\ by\ y\ (y\neq 0):\\
x^2y+4y^2+16y=0\\
We\ substitute\ equation\ (1)\ into\ equation\ (2):\\
16+4y^2+16y=0\\
4y^2+16y+16=0\\
4*(y^2+4y+4)=0\\
4*(y^2+2*y*2+2^2)=0\\
4*(y+2)^2=0\\
Divide\ both\ sides\ of\ the \ equation\ by\ 4:\\
(y+2)^2=0\\
(y+2)*(y+2)=0\\
So,\ y+2=0\\
y=-2.\\

Answer:
x = 45
Step-by-step explanation:
x and (90 - x) are alternate exterior angles and are congruent , then
x = 90 - x ( add x to both sides )
2x = 90 ( divide both sides by 2 )
x = 45
-2 is the answer it’s very easy
You are being asked to solve for K given F.
Subtract 32 from both sides. Put brackets around the two terms on the left.
(F - 32) = 9/5(K - 273) Multiply both sides by 5/9
5/9(F - 32) = K - 273 Now add 273 to both sides
5/9(F - 32) + 273 = K
You are actually converting the F temperature to Celcius first. Once in degrees C, you are then adding 273 to make it degrees Kelvin.
