Answer:
-3
Step-by-step explanation:
C. To find the y-intercept, substitute in 0 for x and solve for y. y-intercept= (0,33)
To find the area of his exclusion zone you would need to understand that a triangle with dimensions of 3, 4, and 5 represent a right triangle.
This means the exclusion zone would be applied to the base and the height of the triangular space.
You would add 2 km to the 3 km, and 2 km to the 4 km to create a new height of 5 km and a new base of 6 km.
Please see the attached picture to understand this.
You will find the area of the total space created by the new triangle and subtract the space represented by the original triangle to find the area of the exclusion zone.
(1/2 x 6 x 5) - (1/2 x 4 x 3)
15 km² -6 km² equals 9 km².
The exclusion space is 9 km².
It is B because angle DBA is supplementary to angle DBE because together they create a straight line which equals 180 degrees.
K = y/x OR y = kx
