It is tree times more value or 15 not sure
Firstly,
thanks for posting this.
81 = 9x9 or 9 squared so at this stage I'm guessing the last two.
x^ 8 = (x^ 4) x (x^ 2) (its called the multiplication rule of indices).
Okay I have approx 14 mins to answer.
No panic
√ 81.x^8 x <span>√ y^5
</span>√ (9x^2 x 9x^6) x <span>√ y^5
</span>= 9x x <span>√ 9x^6 x </span><span>√ y^5
</span>did I just gain time?
√ 9x^6 = <span>√ </span>3x ^3 x <span>√ 3x ^ 3
</span>or 2 . √ 3x^3. <span>√ y^5
</span>more time
okay, so that wasnt successful.
√ 9x^6 =<span>√ </span> (3x^2) x <span>√ </span>(3x^4)
Answer:
C
Step-by-step explanation:
A and B would be very expensive for 2 people, and D is too little, so C would be sensible! Hope this helps!
Per means divide. So..
Step 1. Find ur equation. 63\3
Step 2. Solve ur equation. 63\3 = 21
I think thats right.
Answer:
y = - 5/2x - 23/2
Step-by-step explanation:
b = y - (slope)(x)
b = -4 - (-5/2)(-3)
b = -4 - 15/2 = - 23/2
y = -5/2x - 23/2
