First we want to set the equation equal to zero by subtracting 36 from each side...
x^2 + 5x -36 = 0
Now we factor
(x + 9)(x - 4) = 0
Now set each expression equal to zero and solve...
x + 9 = 0 x - 4 = 0
x = -9 x = 4
Your solution set is
(-9, 4)
Y = -x means y would be the opposite of x
-2 = 2
-1 = 1
0 = 0
1 = -1
2 = -2
Answer:
There are 21/40 L or 0.525 L of vinegar in the container.
Step-by-step explanation:
23 and 3
23 + 3 = 26 and 23 - 3 = 20
It’s basically the same thing as -4=20 so your answer would be -5 or D
