4(x+2)-1/2x=22 we need to get it into the form of a+bx
4x+8-1/2x=22
3.5x=14
f(x)=-14+3.5x

Hope that helps

4(x + 2) - 1/2x = 22
4x + 8 - 1/2x = 22
3.5x + 8 = 22
         -8     -8
3.5x = 14
/ 3.5    /3.5
x = 4

Natali [406]

right 3 units down 5 units

f(x)=x^2

right 3 units = (3,0)

down 5 units = (0,-5)

vertex = (h,k) therefore.

g(x)=(x-3)^2-5

Then convert the vertex form into standard form for the equation in the choice.

g(x)=(x-3)^2-5\\g(x)=(x^2-6x+9)-5+9\\g(x)=(x^2-6x)+4\\g(x)=x^2-6x+4

Thus, the answer is B.

The owner of Darkest Tans Unlimited in a local mall is forecasting the demand for November the one new tanning booth based on th
lorasvet [3.4K]

Answer:

The forecast for November is 235 if August's forecast was 145.

Step-by-step explanation:

The formula for calculating forecast using exponential smoothing is:

F_{t} = F_{t-1}  + \alpha (A_{t-1} - F_{t-1} )

Where Ft = New month forecast

           Ft-1 = Previous month forecast

           At-1 = Previous month actual value

            α = smoothing constant

We are given F₈ = 145 (forecast for August), A₈ = 200 (Actual Value for August), α = 2, and we need to compute the forecast for November. So, We will first calculate the forecast for September then October and then November, step-by-step.

So, forecast for September is:

F₉ = F₈ + α (A₈ - F₈)

    = 145 + 2*(200-145)

    = 145 + 2*55

F₉ = 255

Then, forecast for October is:

F₁₀ = F₉ + α (A₉ - F₉)

     = 255 + 2*(220-255)

     = 255 + 2*(-35)

F₁₀ = 185

The forecast for November is:

F₁₁ = F₁₀ + α (A₁₀ - F₁₀)

    = 185 + 2*(210 - 185)

F₁₁ = 235
