Vertices of the triangle:
<span>J (-2,1), K (4,3), and L (-2,-5) </span>
<span>Area of triangle: 18
or
</span>determinant=
<span>4,3,1 </span>
<span>-2,1,1 </span>
<span>-2,-5,1 </span>
<span>determinant= 4(1+5)-3(-2+2)+1(10+2) = 36 </span>
<span>A = determinant/2
</span>36/2=18
Notice that one side is vertical. Use that side as base.

Answer:
The probability of a van getting rented next is 25%.
Step-by-step explanation:
Probability Formula:
- number of favorable outcomes / the total number of outcomes
Given Information:
- Number of cars sold : 8
- Number of vans sold : 5
- Number of trucks sold : 4
- Number of motorcycles sold : 3
Calculations:
- number of favorable outcomes = 5 (number of vans sold)
- total number of outcomes = 20 (8 + 5 + 4 + 3)
- number of favorable outcomes / the total number of outcomes
- 5/20 = 1/4
Probability of a van getting rented: 1/4 or 25%

Answer:
c (0,-4)
Step-by-step explanation:
-5x+y = -4
4x - 4y =16
Solve the first equation for y since we are using substitution.
-5x+y = -4
Add 5x to each side
-5x+5x+y = -4+5x
y = 5x-4
Substitute this equation y = 5x-4 into the second equation.
4x -4(5x-4) = 16
Distribute the -4
4x - 4(5x) -4(-4) = 16
4x-20x +16 = 16
Combine like terms
-16x +16 =16
Subtract 16 from each side
-16x+16-16 = 16-16
-16x =0
Divide by -16
x=0
But we still need to find y
y = 5x-4
y = 5(0) -4
y = -4
