Does anyone know this? <br> Will mark brainliest !!!!

Answer:

x=4

y=4√5

Step-by-step explanation:

Set up 3 right triangles and mark their respective angles. The largest will have sides (in typical a,b,c[hypotenuse] order) y, z, and 10. The middle 8, x, and y. The smallest x, 2, and z.

Then since they are all similar triangles, using the midde and smaller triangles, set up the proportionin which both A sides when divided are equal to the B sides.

So 8/x = x/2

Cross multiply and get 16=x^2.

The square root of 16 is 4, so x is 4.

Then using the larger and middle triangles, do the same for the A and C sides.

So y/8 = 10/y.

Cross multiply and get 80=y^2.

Find the square root of it, which since it doesn't have a perfect square, you use a calculator or the whatever theorem and get √4*4*5 or simply 4√5.

So x = 4 and y = 4√5

Graph f(x)=2^x+1 and g(x)=-x+4 on the same coordinate plane what is the solution to the equation f(x)=g(x)

Leona [35]

Answer:

x = 1

Step-by-step explanation:

The graph shows the curves cross at x=1.

The solution is x = 1.

<em>Additional comment</em>

I personally find it more convenient to look for the zeros (x-intercepts) of the difference f(x)-g(x). That way, I'm only graphing one function, and I don't have to look all over the graph to try to find the point of intersection. (The solution is always on the x-axis.) The attached graph shows f(x) - g(x) as a dashed green line.
