Answer

The value of \( f(7 - 2) \) is 10.

Solution

To solve the problem: Given the function: \[ f(x) = 3x - x \] Simplify the function: \[ f(x) = 2x \] Now, evaluate \( f(7 - 2) \): \[ f(5) = 2 \times 5 = 10 \] **Answer:** 10

Extra Insights

To find \( f(7-2) \), we first simplify \( 7-2 \) which equals \( 5 \). Now, we need to calculate \( f(5) \). Given \( f(x) = 3x - x \), we can simplify this to \( f(x) = 2x \). Therefore, \( f(5) = 2 \cdot 5 = 10 \). So the value of \( f(7-2) \) is \( 10 \).

An important concern in the study of heat transfer is to determine the steady-state temperature distribution of a thin plate when the temperature around the boundary is known. The figure represents a cross section of a metal beam, with negligible heat flow in the direction perpendicular to the plate. Let \( T_{1}, \ldots, T_{4} \) denote the temperatures at the four interior nodes of the figure. The temperature at a node is approximately equal to the average of the four nearest nodes-to the left, above, to the right, and below. Solve the system of equations below to find the temperatures \( \mathrm{T}_{1}, \ldots, \mathrm{~T}_{4} \). \[ \begin{array}{rl} 4 \mathrm{~T}_{1}-\mathrm{T}_{2}-\mathrm{T}_{4} & =35 \\ -\mathrm{T}_{1}+4 \mathrm{~T}_{2}-\mathrm{T}_{3} & =60 \\ -\mathrm{T}_{2}+4 \mathrm{~T}_{3}-\mathrm{T}_{4} & =70 \\ -\mathrm{T} & \mathrm{~T}, \Lambda \mathrm{~T} \end{array} \] Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A. The unique solution of the system is \( \left(T_{1}, T_{2}, T_{3}, T_{4}\right)=( \) \( \square \) \( \square \) , \( \square \) , \( \quad \) ) ). (Type integers or decimals rounded to the nearest thousandth as needed.) B. The system has infinitely many solutions. C. The system has no solution.
