Answer:
n(A∩B) = 5
Step-by-step explanation:
given,
n(A) = 9
n(B) = 11
n(A U B) = 15
we need to find n(A∩B) = ?
using formula,
n(A U B) = n(A) + n(B) - n(A∩B)
n(A∩B) = n(A) + n(B) - n(A U B)
n(A∩B) = 9 + 11 - 15
n(A∩B) = 5
Answer:
x = -6, y = 12
Step-by-step explanation:
Equations:
y = 2x + 24
y = -2x
Bring the the equation together and add like terms together:
-2x = 2x + 24
-4x = 24
Divide both sides by -4 to isolate x:
![\frac{-4x}{-4} = \frac{24}{-4} \\\\x = -6](https://tex.z-dn.net/?f=%5Cfrac%7B-4x%7D%7B-4%7D%20%20%3D%20%5Cfrac%7B24%7D%7B-4%7D%20%5C%5C%5C%5Cx%20%3D%20-6)
Find y:
y = -2(-6)
y = 12
Verify:
12 =2(-6) + 12
