I'm going to take a guess regarding what you meant to type in:
<span>3x-9 X +6x+5
E(x)= ------- × -------------
2 2
X -9 X +5x+6
3(x+3) 6x+5
becomes E(x) = ----------- * ------------
x-9 5x+6
This cannot be reduced.
Try again to share this problem. Thank you.

The answer to this is five
Answer:
250= 1.50x + 20
Step-by-step explanation:
here 250 is the goal. 1.50 is how much she makes for a cup and x is the number of times to get x much. with how much her parents gave is 20. so we add the money her parents give and 1.50 times x to know the money shegets from all the lemonade selling. graphing the equation but I cant do it on here
God Bless :>
Well 25% is the same as .25 or 1/4. So first you need to add X and Y so X+Y and since it is both you choose D
Answer:
(-∞, -4] ∪ [5, ∞)
Step-by-step explanation:
Hi!
Alright, so greater (or less) than or equal to is denoted with a bracket.
If x is less than or equal to -4, then the bracket is on the left side.
(___, -4]
Because x is <em>any</em> number under or equal to -4, x can range from negative infinity. However, we use a parentheses for infinity because infinity can never truly be reached.
So, x 
-4 = (-∞, -4]
X
5
Equal to = bracket
X is any number above 5, so
[5, ∞)
Because we want both of these, we use the union sign (∪)
so,
= (-∞, -4] ∪ [5, ∞)
