Answer:
-9
Step-by-step explanation:
The question is just asking you to find for what y-value is x -3
<h3>
Answer: 2/3</h3>
Explanation:
The theoretical probability of landing on a multiple of three is 1/3
So the theoretical probability of not landing on a multiple of three is 1-(1/3) = 3/3-1/3 = (3-1)/3 = 2/3
We can think of 1/3 to mean "1 out of 3 times", while 2/3 means "2 out of 3 times".
Remember you can do anything to an equation as long as you do it to both sides
expand by foiling or distributing
4x²-19x-5=-43x-41
add 43x to both sides and add 41 to both sides
4x²+24x+36=0
factor
facotr out of 4
4(x²+6x+9)=0
factor inside
what 2 numbers multiply to get 9 and add to get 6?
3 and 3
4(x+3)(x+3)=0
set to 0
x+3=0
x=-3
x=-3 is answer
You would not subtract 2 from 6 because they are not like terms that you can combine - one of them contains a variable.
You would solve this equation like so:
6z - 2 = 0 The given equation
6z = 2 Add 2 to both sides
z = 1/3 Divide both sides by 6
Answer:
z = 1/3
Hope this helps.
Let the number of copies that must be sold to break even be x, then
3255 + 2.90x = 13.75x
13.75x - 2.90x = 3255
10.85x = 3255
x = 3255/10.85 = 300.
Therefore, 300 <span>copies must be sold to break even</span>
