Answer: y=0,5x²-x-1,5.
Step-by-step explanation:
We summarize (1) and (3):
Substitute b=-1 into (2):
From (5) subtract (4):
Substitute a=0,5 into (4):
Hense:
y=0,5x²-x-1,5.
Answer:
the function has vertical asymptotes at x= 4 and x= -2
this is where the bottom of the function equals zero and the function is undefined at these points
so the correct answer is c
Answer:
p = 4 + q/x - 2/x
q = px + 2 - 4x
Step-by-step explanation:
Answer:
phythaforean theorem:
1 . The square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
2. Find the square root to find the accurate length of the hypotenuse.
distance formula:
1. The distance formula is used to determine the distance, d, between two points.
distance = speed × time
Formula- d= √x2-x1)²+(y2-y1)²
2. It's used for :
-Finding the perimeter of polygons
-Finding the area of rectangles
-Finding the equation of a circle
