I had this on Alcumus...I remember doing it!

Answer: 34

I graphed the equations \(2x+5y>10\) and \(3x+4y>12\), then just found the optimal point.

To find the optimal point, I graphed \(8x+13y=k\) and then found the point where that line first touched the region.

It was at (2.857, 0.857) to the nearest thousandth.

Then I did the math and got 34.

You are very welcome!

I think you mean \(7 \frac{1}{5}\).

This equals 7.2,and 7.2 to the fifth power, or \(7.2^5\), equals 19349.17632.

You are very welcome!

Not really the site to put this, or at least off-topic post...

Now, I'm not an expert, but from what I know, a bunch of students wanted more democratic reform in China. In April of 1989, protests started in Tiananmen square, which led to a small revolution. As May rolled around, over 1 million people joined (from what I can think of).

No graph shown...

An example of a graph would be (x+3)(x-2)(x-5).

What specifically?

\(\frac{3-z}{z+1} \geq 1, 3-z \geq z+1\)

Now we can add z and subtract 1 to both sides, then solve and get the interval notation. Can you solve that?

You are very welcome!

Not sure what the equation is...

If it's 59x(4x)-82 = 154

Then 59*4 = 236x^2-82 = 154, then 236x^2=236 so x^2=1. x = +1 or -1.

If it's 59x(4x-82) = 154

Then 59*4 = 236 and 82*59 = 4838, so 236x^2-4838 = 154. Then 236x^2 = 4992, so x is around 4.6.

You are very welcome!

And Nani means What?

CBF and DEF are similar.

DEF's side lengths are half the length of CBF's. Therefore, if EF's length is 9, then BF's length is double that. Can you solve it?
