Because it’s important to know the equation so that would be easy to know the quadratic formula and easy to solve the problem
Answer:
-10
Step-by-step explanation:
= -X - XY
= -2 - 2×4
= -2 - 8
= -10
therefore, -X - XY = -10
- 3x + 4y = - 11
y = 2x - 4
-3x + 4(2x - 4) = -11
-3x + 8x - 16 = - 11
5x = -11 + 16
5x = 5
x = 5/5
x = 1
y = 2x - 4
y = 2(1) - 4
y = 2 - 4
y = -2
Solution: (1, -2)
Answer:
x = 3
Step-by-step explanation:
Using the rules of logarithms
ln x = ln y ⇒ x = y
ln e = 1
Given
2 ln e ln 5x = 2 ln 15 ( divide both sides by 2 )
ln e ln 5x = ln 15
ln 5x = ln 15, hence
5x = 15 ( divide both sides by 5 )
x = 3
