3(2x+3) -4x=1-4(x-5)

6x+9-4x=1-4x+20

6x+9=1+20

6x+9=21

6x=21-9

6x=12

divide both sides

x=2

If p varies inversely with q, and p = 2 when q = 1, find the<br>equation that relates p and q.

NeTakaya

Answer:

p = $\frac{2}{q}$

Step-by-step explanation:

Given that p varies inversely with q then the equation relating them is

p = $\frac{k}{q}$ ← k is the constant of variation

To find k use the condition p = 2 when q = 1, thus

k = pq = 2 × 1 = 2

p = $\frac{2}{q}$ ← equation of variation

The sum of three consective even integers if the largest number is y

coldgirl [10]

Step-by-step explanation:

If y is largest number, you want y, and the two next smaller even integers smaller than y - i.e. y, y-2, and y-4

The sum of these is y + (y-2) + (y-4).

This simplifies to 3y - 6 or 3(y - 2)

Since we don’t know what y is, this is as far as we can solve the problem.

Find all solutions in the interval [0, 2π). (sin x)(cos x) = 0

Deffense [45]

$\bf sin(x)cos(x)=0\implies 
\begin{cases}
sin(x)=0\\
\measuredangle x=sin^{-1}(0)\\
\measuredangle x=0\ ,\ \pi \\
----------\\
cos(x)=0\\
\measuredangle x=cos^{-1}(0)\\
\measuredangle x=\frac{\pi }{2}\ ,\ \frac{3\pi }{2}
\end{cases}$
