Answer:
Directly proportional relationships always pass through the origin (0,0). There are other linear relationships that do not pass through the origin.
Given :
To Find :
All real value solution of given equation.
Solution :
Simplifying given equation, we get :
sec x( sec x + 2 ) = 0
sec x = 0 and (sec x + 2) = 0
For, sec x = 0 :
x = not defined.
For, (sec x + 2) = 0 :
cos x = -1/2
x = cos⁻¹( -1/2 ) = 2π/3
Therefore, general solution is ( 2nπ ± 2π/3 ), n ∈ Z⁺ .
Answer:
A) (2x + 1)(x + 3)
Step-by-step explanation:
Factor 2x² + 7x + 3
Since 2 is prime (it's only factors are 1 and itself) we know we can start out our factors as..
(2x + a)(x + b)
Three is also prime, so we either have
(2x + 1)(x + 3)
or
(2x + 3)(x + 1)
Foiling (2x + 1)(x + 3) will give us the result we want. So the answer is A
Answer:
-128
Step-by-step explanation:
When it says that x = a number, it means you just need to plug in that number for x in the equation. So in this case, we'd plug in -12 and get:
y = -200-6(-12)
Simplify. According to PEMDAS, we do multiplication first. If a number is in parentheses, you multiply it by the number in front of (to the left) of it. In this case, we multiply -6 x -12 and get:
y= -200+72
Add, and our final answer is:
y=-128
