When graphing an inequality how do you know whether the line should be solid or dotted? plz go into detail and if you have a specific way your remember it plz help i need it for my final exam.

Answer 1
Answer: well, when it comes to graphing an inequality, and you need to know whether the line is solid or dashed, look at the inequality sign.....   (i do not remember that exact terms)  anyway, if it is JUST > or < then it is dashed, that is because you are not including that number, just any number greater than or less than it...

however, if it is Greater than or Equal to 
or
less than or equal to
where these two are including that # by having the "or equal to", it will be solid for it is INCLUDING what ever # we are using...

for example

y > 3 will be dashed

where as     y is greater than or equal to 3 will be solid since the y could be 3

i cant really explain this well...   but i hope i made it somewhat clear

Did Hailey correctly simplify the expression?
A
Yes, Hailey correctly simplified the expression.

B
No, in Step 1, Hailey should have added the exponents instead of subtracting them.

C
No, in Step 2, Hailey should have squared each exponent value instead of multiplying each value by 2.

D
No, in Step 2, Hailey should have also multiplied the exponent of the coefficient by 2 to get 32.

Make R the subject for this formula V = pi r squared h

Answers

V= \pi r^2h\n\n \pi r^2h=V\n\nr^2= (V)/( \pi h)\n\n \boxed{r=\sqrt{(V)/( \pi h)}}
Divide pie on both sides... then square root by h on both sides... so it's "h square root, v divided by pi, equals r.."

Solve for x.
16x - 5 = 18x - 2

Answers

The equation given in the question is
16x - 5 = 18x - 2
16x - 18x = - 2 + 5
-2x = 3
- x = 3/2
- x = 1 1/2
Multiplying both sides of the equation by -1 we get
x = - 1 1/2
So the value of the unknown variable "x" is -1 1/2. I hope there is nothing complicated in the procedure and it is easy for you to understand. In future you can attempt similar kind of problems using this method and will require no additional help from anyone. Only be careful about the calculation part. Other than the calculation part, there is nothing complicated.
When we have a problem like this, we're trying to get the unknown variable by itself. In this case, it's 'x' and we can use addition, subtraction, multiplication, and division to help us. 

16x - 5 = 18x - 2 

Start by subtracting 16x from both sides: 

16x - 5 -16x = 18x - 2 - 16x 
-5 = 2x - 2 

Now add 2 to both sides: 

-5 + 2 = 2x - 2 + 2 
-3 = 2x 

Now divide both sides by 2 to get x: 

-3 / 2 = 2x / 2 

-3/2 = x 

So x = -3/2 which is the same as x = -1 1/2
seems a little easy but hopes this helps :) :D :)
