Answer:
-2
Step-by-step explanation:
The range of the fizgig is -∞ to +∞. The range of the whatzit is -3 ≤ y < ∞. That is, both creatures pass through all y-values between -3 and +∞.
__
Perhaps you want the y-coordinate of a point that both creatures pass through. The point of intersection is found where both equations are satisfied:
2x -4 = y = x^2 -3
x^2 -2x +1 = 0
(x -1)^2 = 0
x = 1
The value of y at that point is ...
y = 2x -4 = 2(1) -4 = -2
The y-coordinate of the point both creatures pass through is -2.
Answer:
The actual mass of the book is between 481 . 5 g and 418 . 5 g.
Step-by-step explanation:
The mass of the book on the scale = 450 g
The percentage error in the scale = 7%
So, the actual mass of the book is 450 g ± 7%
Now, 7 % of the mass 450 g =
⇒ 7% of 450 g = 31.5 g
Now, the Actual mass of the book = 450 g ± 31.5 g
450 g + 31.5 g = 481 . 5 g
450 g - 31.5 g = 418 . 5 g
Hence the actual mass of the book is between 481 . 5 g and 418 . 5 g.
D. All real numbers
The domain can be anywhere from negative infinity to infinity (-♾️ , ♾️ )
To do this problem, we need one more piece of information. He need to know the percent of the quarters that are from New York.
If you had that number, just multiply it by 300.
For example, if 10% of the coins were from New York, just multiply by 0.1.
0.1 x 300 = 30
