Answer:
Step-by-step explanation:
This equation looks complicated.We have to make it easier
let's say x^2/3 = t and x^4/3 = t^2
t^2-10t+21=0 [ we can factorize this equation as a (t-3)(t-7) ]
(t-3)(t-7)=0 [ that means , t can be 3 or 7 ]
But don't forget we have to find x not t so,
t=x^2/3=3 ∛ x^2 = 3 x^2 = 9 x=3 or x= -3
t=x^2/3=7 ∛x^2 = 7 x^2 = 343 x ~18.5 or x ~ -18.5
20y=-5x+10
y=-1/4x+1/2
y-3=-1/4(x-8)
y-3=-1/4x+2
d. y = -1/4x + 5
Answer:
first would be 5-6 and second would be 8-10
Step-by-step explanation:
Answer:
an + 1 = an + 2n -1 ,a 1=1
a8= 50
Step-by-step explanation:
an+1=an+2n-1,a1=1
a6=a5+2x5-1
a6=26
a7=26+11
a7=37
a8=37+13
a8=50
Answer:
1. x= 8
2. x= 6
3. x= 7
4. x= -8
