Answer:
The value of k is 4.
Step-by-step explanation:
To find the missing coordinate, we can use the slope equation and plug in all known values.
m(slope) = (y2 - y1)/(x2 - x1)
-1 = (k - 0)/(-2 - 2)
-1 = k/-4
Now we can solve using cross multiplication.
-1 = k/-4
k*1 = -1*-4
k = 4
Answer:
See below:
Step-by-step explanation:
So, for starters, g(x) is just a fancy way of saying that it is a function, it's basically used as 
and you can usually use g(x) or y whenever you want unless its a special situation.
So we can replace g(x) with y as there aren't any other functions we need to deal with.
y = 3x + 2
y = 11
Now that its simplified, we can see its a simple problem
After combining, we get 11 = 3x + 2
After solving, we get x = 3
The answers comes to be for every 1 unit of pure acid (100%) add three units of 20% and you get the desired 40%
so if you need 40 L (i don't know what container sizes there are so i can't give you an exact amount just add 1 part 100% acid and 3 parts 20% acid) <span />
You plug in 3 where you see x and 4 where you see y
3*3+1/4*4^2
9+1/4*16
9+4
13
Remember to follow PEMDAS (order of operations)
parenthesis, exponents, multiply, divide, add, subtract<span />
