Answer:
x = −6
Explanation:
5x + 7y = -23
Y = -2x - 11
Substitute -2x - 11 for y in 5x + 7y = -23
5x + 7(−2x − 11) = −23
Simplify both sides of the equation
5x + 7(−2x − 11) = −23
5x + (7)(−2x ) + (7)(−11) = −23 (Distribute)
5x + −14x + −77 = −23
(5x + −14x) + (−77) = −23 (Combine Like Terms)
−9x + −77 = −23
−9x − 77 = −23
Add 77 to both sides
−9x − 77 + 77 = −23 + 77
−9x = 54
Divide both sides by -9
−9x / -9 = 54 / -9
x = -6

The core uses the value of the Pythagorean theorem and special angles.
Answer:
62.5
Step-by-step explanation:
Data provided in the question:
Actual demand = 59
Previous forecast = 64
Alpha = 0.3
Now,
The forecast for the next period be using simple exponential smoothing will be given as
= [ Alpha × Actual demand ] + [ (1 - Alpha) × Previous forecast ]
= 0.3 × 59 + [ ( 1 - 0.3 ) × 64 ]
= 17.7 + 44.8
= 62.5
Simplify both sides of the equation, add 6x to both sides, subtract 48 from both sides, then divide both sides by 70. Your answer would be x= -1
Answer:
The Distributive Property states that when a number in parentheses is next to a number, you distribute the number outside of the parentheses and multiply by each of the numbers in parentheses.
5(10+x)=5(10)+5(x)=50+5x
