Answer:
A
Step-by-step explanation:
Given
- 1 ← a difference of squares which factors in general as
a² - b² = (a - b)(a + b)
here = (x²)² ⇒ a = x² and b = 1
- 1 = (x² - 1)(x² + 1)
x² - 1 ← is a difference of squares and factors as
x² - 1 = (x - 1)(x + 1), so
(x² - 1)(x² + 1) = (x - 1)(x + 1)(x² + 1), hence
- 1 = (x - 1)(x + 1)(x² + 1) → A

The interception of the two lines is the solution point.
Answer:
(1/4,-121/8)
Step-by-step explanation:
1. F(3)= -2(3)-5
-6-5
F(3)=-11
2. F(3)= -2(3)^2-4
-6^2-4
36-4
F(3)=32
3. F(x)=−2x−5
For: x=−2, f(x) is:f(−2)=(−2×−2)−5=4−5=−1
For: x=−1, f(x) is:f(−1)=(−2×−1)−5=2−5=−3
For: x=1, f(x) is:f(1)=(−2×1)−5=−2−5=−7
For: x=2, f(x) is:f(2)=(−2×2)−5=−4−5=−9
The Range is:
{−1,−3,−7,−9}
4. -80, -110
Answer:
$7.20
Step-by-step explanation:
20% is the same as 0.2 or 2/10, which simplifies to 1/5.
1/5*36=36/5=7.20
Or you could straight up to 20%*36=7.20
