Answer:

\mathrm{A.\:}\begin{cases}3x+2y=170,\\4x+6y=360\end{cases}\\\\\mathrm{B.\:} \$ 30

Step-by-step explanation:

We can write the following system of equations:

\begin{cases}3x+2y=170,\\4x+6y=360\end{cases}, with variables as defined in the question.

Multiply the first equation by -3 and add both equations to isolate and solve for x:

\begin{cases}-9x-6y=-510,\\4x+6y=360\end{cases}\\-5x=-150,\\x=\fbox{$\$ 30$}.

Natalija [7]
Ggalaxy, your question is quite convoluted, but I'll answer it anyway. 15/6=2.5. 2.5x4=10 and 2.5x2=5. 10+5=15 vegetables (This includes the 4 carrots and 2 potatoes.)

Answer:
Choice A: stretched horoxontally by a factor of 2 and translated up by 3 units

Explanation:
The original graph is:
y = log(x)
The modified one is:
y = log(2x) + 3

We can note that 2 changes occured:
1- A 3 has beed added to the whole gaph. This means that the curve has been moved (translated) upwards by 3 units

2- The x inside the log is miltiplied by 2. This means that the graph is stretched horizontally by the factor added (2).

Combining these two, we will find that the correct choice is A

Hope this helps :)
