Let's analyze each statement based on the given information:

### Given:
- **Jacksons** are **40 miles closer** to the cabin than the **Miligans**.
- **Jacksons' speed**: **50 mph**
- **Miligans' speed**: **60 mph**
- Both families leave at **9 a.m.** on Saturday.

### 1. **The equation for the Jacksons is $$ y = 40x + 50 $$ and the equation for the Miligans is $$ y = x + 60 $$. True or False?**

**False.**

**Explanation:**
- Let $$ D $$ be the initial distance of the Jacksons from the cabin. Then, the Miligans are $$ D + 40 $$ miles away.
- For the Jacksons: Distance from cabin after $$ x $$ hours is $$ y = D - 50x $$.
- For the Miligans: Distance from cabin after $$ x $$ hours is $$ y = (D + 40) - 60x $$.

The proposed equations $$ y = 40x + 50 $$ and $$ y = x + 60 $$ incorrectly model the relationship because they suggest the distance from the cabin **increases** with time, whereas it should **decrease**. Additionally, the coefficients and constants do not align with the given speeds and distance differences.

### 2. **The cars will reach the same point in 4 hours. True or False?**

**True.**

**Explanation:**
To find when both cars are at the same distance from the cabin:
- **Jacksons**: $$ y = D - 50x $$
- **Miligans**: $$ y = (D + 40) - 60x $$

Setting them equal:
$$
D - 50x = D + 40 - 60x \
10x = 40 \
x = 4 \text{ hours}
$$

Thus, both cars will be at the same point **4 hours** after departure, which is at **1 p.m.**.

### 3. **If the cabin is 400 miles away, it will take the Jacksons 7 hours and 12 minutes to get there. True or False?**

**True.**

**Explanation:**
Assuming the cabin is **400 miles** away from the **Miligans' starting point**, the Jacksons are **40 miles closer**, so:
$$
\text{Jacksons' distance to cabin} = 400 - 40 = 360 \text{ miles}
$$
Time taken by Jacksons:
$$
\frac{360 \text{ miles}}{50 \text{ mph}} = 7.2 \text{ hours} = 7 \text{ hours and } 12 \text{ minutes}
$$

### 4. **The two cars will reach the same point at noon. True or False?**

**False.**

**Explanation:**
The families depart at **9 a.m.**, so **noon** is **3 hours** later. According to statement 2, they reach the same point in **4 hours** (1 p.m.), not at noon.

Furthermore, checking their positions at **3 hours**:
- **Jacksons**: $$ y = 360 - 50 \times 3 = 210 \text{ miles} $$ from cabin.
- **Miligans**: $$ y = 400 - 60 \times 3 = 220 \text{ miles} $$ from cabin.

They are **not** at the same point at noon.

### **Summary of Statements:**
1. **False**
2. **True**
3. **True**
4. **False**

**Answer:**

1. False  
2. True  
3. True  
4. False
1. False 2. True 3. True 4. False
