The answer is B. because it is 6:9 which simplifies down to 1:3
Answer:
x=√2, x=-√2, x= 3 and x=-3
Step-by-step explanation:
We need to solve the equation x^4 - 11x^2+18=0
We can replace x^4 = u^2 and x^2 = u
So, the equation will become
u^2 -11u+18 = 0
Factorizing the above equation:
u^2 -9u-2u+18 =0
u(u-9)-2(u-9)=0
(u-2)(u-9)=0
u=2, u=9
As, u = x^2, Putting back the value:
x^2 =2 , x^2 =9
taking square roots:
√x^2 =√2 ,√x^2=√9
x=±√2 , x = ±3
so, x=√2, x=-√2, x= 3 and x=-3
Answer:
C. 2, -2, -6
Step-by-step explanation:
18, 14, 10, 6, ?
18 - 4 = 14
14 - 4 = 10
10 - 4 = 6
6 - 4 = 2
2 - 4 = -2
-2 - 4 = -6
They are subtracting each number by 4 to get the next one that continues.
Hope this helped!
Have a supercalifraglisticexpialidocious day!
Add the numbers they equal 30 then u divide 30 by 2 since it’s an odd number and you get 15. so 15 is your answer
Answer:
y+1=9(x+3)
Step-by-step explanation:
Since the equation for point slope form is y-y₁=m(x-x₁)
enter the given points (-3,-1)
y-(-1)=9(x-(-3))
y+1=9(x+3) <-- point slope form
