Answer:
Step-by-step explanation:
Given
- f(x) = 2x
- g(x) = x² - 1
- (f - g)(x) = ?
Solution
- (f - g)(x) = 2x - (x² - 1) = 2x - x² + 1 = -x² + 2x +1
- (f - g)(x) = -x² + 2x +1
The answer would be 8x+ 12 - 7x or 20x - 7x
To find the x-intersept, just set y = 0 into the equation, then solve it for x:
-2x + 5 * 0 = -10
-2x + 0 = -10
-2x = -10
x = (-10)/(-2)
x = 5 <----- this is the answer.
I hope this helps. =)
Answer:
V = 118 in³
Step-by-step explanation:
The volume of a cone of radius r and height h is V = (1/3)(π)(r^2)(h).
In this case, the volume is V = (1/3)π(3 in)^2·(6 in), or π(18 in³)
Using 3.14 as the approximate value of π, we get V = 118 in³
If Morgan is 15 years younger then Mrs.Santos and there combined age is 442 that means that Mrs.Santos is 221, and Morgan is 206.
