Q= -1. I did this problem by elimination, by multiplying the first one by -4 and the second by 3, to cancel out the p. I ended up with -7q=7. I divided both sides by -7, and got q=-1.

Solnce55 [7]

Answer:

(B) 2

Step-by-step explanation:

=> \frac{\sqrt{32}+ \sqrt{48} }{\sqrt{8}+\sqrt{12}  }

=> \frac{4\sqrt{2}+4\sqrt{3}  }{2\sqrt{2}+2\sqrt{3}  }

=> \frac{4(\sqrt{2}+\sqrt{3})  }{2(\sqrt{2}+\sqrt{3)}  }

Answer:

y=\frac{x+2}{4} or y = 0.25x + 0.5

Step-by-step explanation:

You need to try change the subject from x to y.

x = 4y - 2

We first move -2 to the left, making the equation

x + 2 = 4y i.e.

4y = x + 2

We then divide both sides by 4.

y=\frac{x+2}{4} or y = 0.25x + 0.5

We now have successfully made y the subject, and effectively solving the equation.
