Answer:
The solution is x = -2, y = -3
Step-by-step explanation:
Let's start with the equation 3x + y = -9
Substitute the y for 5x+7 seen in the second equation
Now you have 3x + (5x+7) = -9
Lets solve:
Let's add the x's
Now we have 8x + 7 = -9
Substracy seven from each side
Now we have 8x = -16
Now let's divide 8 on each side
Now we have x = -2
Now lets plug in -2 to the second equation
The second equation is y = 5x+7
When we plug in -2 we get y=5(-2)+7
We multiply
We now have y = -10+7
Add
y = -3
The solution is x = -2, y = -3

Answer:
1. Median
2. Altitude
3. Altitude
4. Neither
Step-by-step explanation:
Median- splits the side into two congruent parts
Altitude- Makes a right angle
1. Splits the side. Median
2. Makes a right angle. Altitude
3. Makes a right angle. Altitude
4. Doesn't make a right angle or split the sides. Neither
