He needs 1/2 cup because 3/4-1/4=2/4 which is simplified to 1/2
Alicia: 43 miles/hour
Trish: 46 miles/hour
so Alicia drives at a slower rate
Answer:
K(-4,8) is the ortho center.
Step-by-step explanation:
In a right angled triangle, The vertex of the right angle is the ortho center.
Here we are given
J(-4,-1), K(-4,8) & L(2,8)
Using distance formula we get



So we can say that

By converse of pythagorean theorem we get

Hence the Vertex of the right angle is K(-4,8)
K(-4,8) is the ortho center.
It is the origin of a graph; where the x-axis and y-axis intercept .
