Why is 4b-7-3b+9 equal to b+2

Mathematics
1 answer:
rodikova [14]3 years ago

The first expression can be simplified by combining like terms.

First, the terms "4b" and "-3b" can be combined to form "b"
Then, the terms "-7" and "9" can be combined to form "2"

Finally, we simply put these two final terms together, to form "b+2"

Hence, 4b-7-3b+9 is equal to be + 2.

Hope this helps!

Convert R=(12)/4+8sin the theta to rectangular form
kompoz [17]
r=\dfrac{12}{4+8\sin\theta}=\dfrac3{1+2\sin\theta}

Let y=2\sin\theta, and recall that in polar coordinates, r=\sqrt{x^2+y^2}. This means you have

\sqrt{x^2+y^2}=\dfrac3{1+y}

You can stop there, or try to find something that looks somewhat nicer.

x^2+y^2=\dfrac9{(1+y)^2}
