The minimum and maximum temperature on a cold day can be modeled by the equation 2[x-6]+14=38 What are the min and max temperatu
SashulF [63]
Here are the steps to calculating the given equation:

Distribute 2 to x and 6: 2x-12+14=38
Group like terms: 2x+(-12+14)=38
Combine like terms: 2x+2=38
Subtract number on 'x' side: 2x+2-2=38-2
Simplify: 2x=36
Divide: 2x/2=36/2
Simplify: x=18
Label with correct terms: 
I cannot do this because you did not provide sufficient information, I would need to know what the difference between the two, or if 'x' stood for one particular temperature. Hope that helped enough with what you provided.

Assignment: Function Equations Investigation
kakasveta [241]

Function 1:

For the given table

\begin{array}{cc}x&f(x)\\-2&-2\\-1&1\\0&4\\1&7\end{array}

you can plot the graph of the function (see first attached diagram). This function is linear and has equation f(x)=3x+4.

Function 2:

For the given function f(x)=-2x+3 you can create a table

\begin{array}{cc}x&f(x)\\-2&7\\-1&5\\0&3\\1&1\end{array}

and plot the graph (see second attached diagram).

Function 3:

For the given graph of the function, you can find the function:

\dfrac{x-0}{6-0}=\dfrac{y-(-3)}{0-(-3)},\\ \\\dfrac{x}{6}=\dfrac{y+3}{3},\\ \\2(y+3)=x,\\ \\y=\dfrac{1}{2}x-3.

Thus, the equation of the function 3 is f(x)=\dfrac{1}{2}x-3.

The table will take a look

\begin{array}{cc}x&f(x)\\-2&-4\\-1&-3.5\\0&-3\\1&-2.5\end{array}
