What should be subtracted from 2a+8b+10 to get -3a+7b+16?

2 answers:

8 0

2a + 8b + 10
-3a + 7b + 16

2a + 8b + 10 - 5a -b +6= -3a + 7b +16
Next, group the similar figures
2a - 5a + 8b - b + 10 + 6= -3a + 7b + 16

2a +8b+10 - A = -3a+7b+16
A=2a+8b+10 - (-3a+7b+16)
A= 2a +8b+10 +3a - 7b -16
A = 5a +b -6

Find the angles between -pi and pi that satisfy:<br><br> (−√3) sin(v)+cos(v)=√3

MAXImum [283]

Observe that

$\sin\left(\dfrac\pi6-v\right)=\sin\dfrac\pi6\cos v-\cos\dfrac\pi6\sin v=\dfrac12\cos v-\dfrac{\sqrt3}2\sin v$

In the original equation, divide both sides by $\dfrac12$ :

$-\sqrt3\sin v+\cos v=\sqrt3\implies\dfrac12\cos v-\dfrac{\sqrt3}2\sin v=\dfrac{\sqrt3}2$

$\implies\sin\left(\dfrac\pi6-v\right)=\dfrac{\sqrt3}2$

Next,

$\sin x=\dfrac{\sqrt3}2\implies x=\dfrac\pi3+2n\pi,x=\dfrac{2\pi}3+2n\pi$

where $n$ is any integer. Then

$\sin\left(\dfrac\pi6-v\right)\implies v=-\dfrac\pi6-2n\pi,v=-\dfrac\pi2-2n\pi$

Fix $n=0$ to ensure $-\pi$ , so that

$v=-\dfrac\pi6,v=-\dfrac\pi2$

How does geography influence your neighborhood?

Snezhnost [94]

Human characteristics of your neighborhood come from humans ideas and actions. They include bridges houses, and parks. Human characteristics of places also include land use, density of population, language patterns, religious, architecture, and political systems.
