Answer:
Step-by-step explanation:
Given that,
x^8/x^a=x²
Applying indices
Division rule a^m ÷ a^n = a^(m-n)
Then,
x^8/x^a=x²
x^(8-a)=x²
For this to be equal means that, the power are equals since they have the same base
Then, 8-a=2
8+2=a
So, a=10
Taking the second equation
(x^6)^b=x¹²
Using indices again
x^(6b)=x¹²
Also, for this to be equal
6b=12
Then, b=12/6
b=2
Then, b=2 and =10
We need to find b-a.
b-a=2-10=-8
Then, the answer to b-a is -8

Answer:
C
Step-by-step explanation:
∠1 = 3x + 18 {Vertically opposite angles}
∠1 + 28° = 90
3x + 18 + 28 = 90
3x + 46 = 90
3x = 90 - 46
3x = 44
x = 44/3

Answer:
x = -4
Step-by-step explanation:
x+y = -10 -------- (1)
x-y = 2 ------- (2)
from (1)
x+y = -10
y = -10-x -------- (3)
substitute (3) into (2)
x-y = 2
x-(-10-x) = 2
x+10+x = 2
2x = 2-10
2x = -8
x = -8/2
x = -4
The estimate is about 15.60
