I could only do b

3(2x + 4) = 2+6x+10

6x+12 = 2+6x+10

6x- 6x = 2+10-12

0x/0 = 0/0

x = 0

I think

I need help with this question!!!

Answer: B. positive 6

Step-by-step explanation: Addomg the positive number to a negative number would turn it to a positive eventually. So u covert your factions to decimals to better see the resemblance. And 1 1/2 is the same as 1.5, and 2 1/10 is the same as 2.1 but it’s easier to deal with decimals. So then just add the positive to the negative sense 1 1/2 is closer to zero. I hope this helps I’m not the best at explaining things

Answer:

  • changes by 120 for each copy
  • is 1800 if none are sold

Step-by-step explanation:

Let's look at the second question first.

x is the number of copies Chau sells. If he doesn't sell any copies, then x = 0. To find Chau's pay, we use x=0 in the equation, and solve for y.

  120×0 +1800 = y

  0 +1800 = y

  1800 = y

Chau's pay when he sells no copies is $1800.

__

If Chau sells 1 copy, then his pay is ...

  120×1 +1800 = y = 1920 . . . . . . . use the equation with x = 1

The increase in Chau's pay is 1920 -1800 = 120.

Chau's pay changes by $120 for each copy he sells.

This is my next Trigonometry question I am needed help on- I just want to be sure I've got it right, or if not, then the steps I
Reptile [31]
\bf cos(\theta)=\cfrac{3}{5}\cfrac{\leftarrow adjacent=a}{\leftarrow hypotenuse=c}
\\\\\\
c^2=a^2+b^2\implies \pm\sqrt{c^2-a^2}=b\implies \pm\sqrt{5^2-3^2}=b
\\\\\\
\pm\sqrt{16}=b\implies \pm4=b

so, plus or minus?  well, the angle is in the 1st quadrant, and on that quadrant, both cosine and sine are positive, so 4 = b

\bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(\theta)=\cfrac{4}{3}
