3-2(2x+2)-(4x+2)
Pretend that there is a -1 in front of the second bracket
3-2(2x+2)-1(4x+2)
Multiply the first bracket by 2
Multiply the second bracket by -1
(-2)(2x)(-2)(2)=-4x-4
(-1)(4x)(-1)(2)= -4x-2
3-4x-4-4x-2
-4x-4x+3-4-2
Do 3-4-2 first
3-4-2
-1-2
=-3
-4x-4x-3
-8x-3
Answer: -8x-3

Answer: PQ=5, QR=radical 61= 7.81, angle: 50degrees,</span>Why:PQ=|-3|+2=5PR=6<span>angle Alfa, so there is right angle triangle PQR so I can use following formula:</span>PQ^2 + RP^2=QR^2;25 + 36=QR^2;QR=radical 61<span>also I can use: sinus (angle)=PR/QR;</span><span>sin(angle)=6/radical61=0.76822 which gives angle to be little bit more than 50 degrees{sinus 50 degrees=<span>0,7660</span>}. </span>
800-500 =300 5 times 100=500 it decreases by 100 each year
I hope that helps
Answer: C
Step-by-step explanation:
In this problem, you will need to know the different properties of the equation. Which part tells you if this graph is negative or positive? and more.
First, we notice an x as the exponent. This tells us that this is an exponential equation. Therefore, we can eliminate B and D.
Next, how do we know if the equation is growth or decay?
The 3 and 1.5 are both positive. This tells us that this is equation is exponential growth.
You can always graph the equation to make sure you are correct.
