Answer:
b.(-2, -1), (3, 4)
Step-by-step explanation:
We are given function as

We can verify each intervals
At (-6,-5):
Firstly we will plug x=-6

now, we can plug x=-5

since, both are positive values
So, zeros can not lie between them
At (-4,-3):
Firstly we will plug x=-4

now, we can plug x=-3

since, both are positive values
So, zeros can not lie between them
At (-2,-1):
Firstly we will plug x=-2

now, we can plug x=-1

since, one is positive and another is negative
So, zeros will lie between them
At (3,4):
Firstly we will plug x=3

now, we can plug x=4

since, one is positive and another is negative
So, zeros will lie between them
zeros will be between
(-2, -1), (3, 4)
Answer:
abc = 8
Step-by-step explanation:
ab=2, bc=4 and ac=8
Multiply all of these together
ac = 2
Multiply by bc =4 (the left on the left and the right on the right)
ac * bc = 2*4
ab^2c =8
Multipy by ac =8 (the left on the left and the right on the right)
ab^2c *ac = 8*8
a^2 b^2 c^2 = 64
Take the square root of each side
sqrt(a^2 b^2 c^2) = ±sqrt(64)
abc = ±8
Since a,b,c are positive numbers
abc = 8
Answer:
none
Step-by-step explanation:
Because X and Y are different variables.
Answer:
The value of x in given question will be 
Step-by-step explanation:
Given data:
7x-c=k
Now,
7x-c=K
7x=K+c

Therefore,
The value of x in given question will be : k+c/7
