The area of a triangle is base length x height then divide all by 2,
so 12 x 10 /2
=60 ft²
-5/3, -0.1, 0.7, sqrt2, sqrt5
Answer:
They are perpendicular because they have slopes that are opposite reciprocals of −5 and one-fifth.
Step-by-step explanation:
slope is the number next to x
Answer:
y=-1/2x-1/2
Step-by-step explanation:
For this, you need to use the point slope formula, (y-y1)=m(x-x1). The slope, m, would be -1/2 since the line we're looking for is perpendicular (meaning the slope is the negative reciprocal of the original slope). The x1 would be 3, and the y1 would be 1.
(y-y1)=m(x-x1)
(y-1)=-1/2(x-3)
y-1=-1/2x-3/2
y=-1/2x-1/2
