Y=-3x+7..................
boyakko [2]3 years ago

Answer:

y = -3x +7

Step-by-step explanation:

The equation for a line is: y = mx + b

m = slope

x = the x-value

y = the y-value

b = the y-intercept

Since the y-intercept is 7, we know the first part of the equation is: y = mx +7

Also, since the line is decreasing from right to left, m is going to be negative. A way to calculate the m is rise/run. Count how many blocks it is going horizontally (run)and how many blocks it is increasing/decreasing when going to the right (rise). Then divided the "rise" over "run". Another way is to choose two points. Now use the equation y1-y2/x1-x2,

or  y2-y1/x2-x1. I am going to show using the equation.

My two points are (0,7) and (2,1)

change in y (rise):7-1 = 6

change in x (run): 0-2 = -2

6/-2 = -3. Your slope is -3. Now lets put it all together.

y = -3x +7

You can see that for every square moved to the right ONCE the y value is decreasing by 3 each time.

ANEK [815]

Hey there! The answer will be below

B is the correct answer

Because in B the last 3 numbers are 500 (estimate) so 34,500 would be rounded to 35,000.Plus B makes the most sense.

Hope that helps!

Given an actual demand of 59, a previous forecast of 64, and an alpha of .3, what would the forecast for the next period be usin
marshall27 [118]

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

17 - 6 * 10 / 2 + 12 is what​
Zarrin [17]

Answer:

- 1

Step-by-step explanation:

Using the order of operations PEMDAS ( parenthesis, exponents, multiplication, division, addition, subtraction )

Given

17 - 6 × 10 ÷ 2 + 12 ← perform multiplication

= 17 - 60 ÷ 2 + 12 ← perform division

= 17 - 30 + 12 ← perform addition/ subtraction from left to right

= - 13 + 12

= - 1
