If (x, 9) is a solution to 5x - 2y = 12, what is the value of x ?
lina2011 [118]
X= 6


Explanation:

y=9 so rewrite the equation like this:


5x-2(9)=12

Multiply -2 by 9:


5x-18=12

Cancel out the -18:


5x-18=12
+18 +18


5x=30


Divide both numbers by 5:


5x/5 = 30/5


As an answer, you will get x=6:

Hope this helped:)

Solve the differential equations dy/dx=((xy^2)+x)/y
arsen [322]

\displaystyle \dfrac{dy}{dx}=\dfrac{xy^2+x}{y}\\ \dfrac{dy}{dx}=\dfrac{x(y^2+1)}{y}\\ \dfrac{y}{y^2+1}\, dy=x\, dx\\ \int \dfrac{y}{y^2+1}\, dy=\int x\, dx\\ \dfrac{\ln (y^2+1)}{2}=\dfrac{x^2}{2}+C\\ \ln(y^2+1)=x^2+C\\ y^2+1=e^{x^2+C}\\ y^2=e^{x^2+C}-1\\ y=\sqrt{e^{x^2+C}-1} \vee y=-\sqrt{e^{x^2+C}-1}\\ \boxed{y=\sqrt{Ce^{x^2}-1} \vee y=-\sqrt{Ce^{x^2}-1}}\\

What is the length of x in the triangle shown
ivann1987 [24]
Since this is a right triangle the angle opposite the side 17 is also 45°

So this can be solved in two ways...

The Law of sines...

x/sin90=17/sin45

x=17/sin45

x≈24.04 to nearest hundredth

or by realizing that both sides are 17 because they are both opposite 45° angles then the hypotenuse x is

x=√(2*17^2)

x=√578

x≈24.04
