Using the given information, the coordinates of B are (-7, 4)
<h3>Midpoint of a Line </h3>
From the question, we are to determine the coordinates of B.
Given a line with endpoints (x₁, y₁) and (x₂, y₂), then the midpoint of the line is
((x₁+x₂)/2, (y₁+y₂)/2)
From the given information,
The midpoint of AB is M(-3, 0)
and
The coordinates of A are (1,-4)
Let the coordinates of B be (x₁, y₁)
Then,
-3 = (1 + x₁)/2
-6 = 1 + x₁
x₁ = -6 -1
x₁ = -7
Also,
0 = (-4 + y₁)/2
0 = -4 + y₁
y₁ = 0 + 4
y₁ = 4
Hence, the coordinates of B are (-7, 4)

Answer:
5 units
Step-by-step explanation:
An isosceles triangle is a triangle with two legs that have the same length. The perimeter of a triangle is the sum of the lengths of all sides of the triangle. Now taking this into account, we know that:
2L + B = 14 units
Where:
L is the measure of one leg
B is the measure of the base
Since two legs are the same and the base is 1 less, this means the measure of each leg would be:
B = L -1
Now we have two equations:
2L + B = 14 units
B = L- 1
We plug one equation into the other and make 1 equation:
2L + (L-1) = 14 units
Get rid of the parentheses:
2L + L - 1 = 14
Combine like terms:
3L - 1 = 14
Add 1 to both sides of the equation:
3L - 1 + 1 = 14 + 1
3L = 15
Divide both sides by 3:
3L/3 = 15/3
L = 5
So the length of a leg is 5 units
Let's check!
B = L - 1
B = 5 - 1
B = 4
Then we use that to solve for the perimeter:
2L + B
2(5) + 4
10 + 4 = 14
