1. **Problem:** Given $4 = ج(س) = 7$, find $س$. 2. **Understanding the problem:** The equation states that the function $ج$ evaluated at $س$ equals both 4 and 7, which is contradictory unless clarified. Assuming the problem means $ج(س) = 4$ and $ج(س) = 7$ are two separate values or a typo, we focus on the first equation $ج(س) = 4$. 3. **Formula and rules:** To find $س$ from $ج(س) = 4$, we need the explicit form of $ج(س)$, which is not provided. Without it, we cannot solve for $س$. 4. **Intermediate work:** Since no function form is given, we cannot proceed. 5. **Conclusion:** More information about the function $ج$ is needed to find $س$. 1. **Problem:** Given $ص(س) = 9$ and $ص(ص2) = 16$, find $ن(س \times ص)$. 2. **Understanding the problem:** We have values of $ص$ at certain points and want to find $ن$ at the product $س \times ص$. 3. **Formula and rules:** Without explicit forms of $ص$ and $ن$, or their relationship, we cannot compute $ن(س \times ص)$. 4. **Intermediate work:** Insufficient data. 5. **Conclusion:** More information is needed. 1. **Problem:** Given $ص$ is proportional to $س$, and $ص=0$ when $س=3$, find the constant of proportionality. 2. **Formula:** If $ص$ is proportional to $س$, then $ص = k \times س$ where $k$ is the constant of proportionality. 3. **Using the condition:** $0 = k \times 3$ implies $k = 0$. 4. **Conclusion:** The constant of proportionality $k = 0$. 1. **Problem:** Given $ح > 3$, find the quadrant of the point $(5, ب - 3)$. 2. **Understanding:** The quadrant depends on the signs of $x=5$ and $y=b-3$. 3. **Since $x=5 > 0$, the point is in quadrant I or IV depending on $b-3$. 4. **Without $b$ value, quadrant cannot be determined. 1. **Problem:** Given point $(2, ب)$ lies on the graph of $د(س) = س + 3$, find $د(ع)$. 2. **Using the function:** $د(2) = 2 + 3 = 5$, so $ب = 5$. 3. **$د(ع)$ is not defined without $ع$ value. 1. **Problem:** Solve $250 = 24 + ...$ 2. **Calculation:** $... = 250 - 24 = 226$. 1. **Problem:** Given $د(س) = 4$, find $د(2)$ and $د(3)$. 2. **Since $د(س)$ is constant 4, $د(2) = 4$ and $د(3) = 4$. 1. **Problem:** Given $ص=9$ and $ص$ is proportional, find $ص$ proportional value. 2. **Insufficient data to solve. 1. **Problem:** From measures of dispersion, select the correct option. 2. **Insufficient data to solve. **Summary:** The first distinct problem is about finding $س$ given $4 = ج(س) = 7$, which is contradictory or incomplete. The next solvable problem is about proportionality where $ص=0$ when $س=3$, leading to constant of proportionality $k=0$. **Final answer for the first solvable problem:** $$k=0$$
