From the second equation y=-1-x so we can write -2x²+3x-1=-1-x.
So -2x²+4x=0, 2x(-x+2)=0, therefore x=0 or 2 and the corresponding y values are -1 and -3.
We can write the answers as ordered pairs (0,-1) and (2,-3).
Answer:
D. 3x² - x - 6
Step-by-step explanation:
If f(x) = 3x² - 4 and g(x)= x+2, find .
We know that (f - g)(x) = f(x) - g(x)
Then
(f - g)(x) = (3x² - 4) - (x+2)
= 3x² - 4 - x - 2
= 3x² - x - 4 - 2
= 3x² - x - 6
Step-by-step explanation:
Diameter = 10 in
Radius = 5 in
Area of quarter circle = 1/4πr²
Area = 1/4 × 314/100 × 5 × 5
Area = 157/8 = 19.6 in²
Answer:
(1, 8, 6) or (2, 12, 6) or (3, 24, 6)
Step-by-step explanation:
The last number must be 6:
1/2 = 6/12
The other two numbers cannot be 6, but can have several values:
1/2 = 1/8 +3/8 = 6/12
1/2 = 2/8 +3/12 = 6/12
1/2 = 3/8 +3/24 = 6/12
__
There are a variety of negative solutions as well. For example, ...
1/2 = -8/8 +3/2 = 6/12
