Hello from MrBillDoesMath!
Answer:
Choice B.
Discussion:
From the first step
324 x^6 y^ 8 =
2^2 * 3^4 * x^2 * x^4* y^8
so the fourth root of this is
2 ^(2/4)* 3^(4/4) x^(2/4)* x^(4/4)*y^(8/4) =
2^ (1/2) * 3^1 * x^(1/2) * x^(1)* y^ (2) =
(2x)^(1/2) * 3 * x * y^2 =
3 * x * y^2 * sqrt(2x) =
3 * x * y^2 * ( (2x)^2) ^ (1/4)) =
3 * x * y^2 * (4x^2) ^ (1/4)
which is choice B
Thank you,
MrB
Answer:
-63
Step-by-step explanation:
To find the discriminant, you just need to apply the square root part of the quadratic formula:
Sqrt (b^2 - 4ac)
Sqrt (9 - 4 x 1 x 18)
Sqrt (-63)
The number inside of the square root would be the discriminant.
A negative discriminant means that the quadratic would result in imaginary solutions.
Yes, the equation specifies a function with independent variable x.
Equation: 6x + 19y = 7
This can be put in y = mx + b form,
6x + 19y = 7
19y = -6x + 7
y = -
x + 
Since the equation can be put in the form of a linear function, the domain is all read numbers (-∞,∞) or -∞ < x < ∞ .
You would do 81-17=64 because they had eighty one dollars in the beginning and 17 dollars left. then divide it by 8 because that is how many books were bought.
Equation: i’m not sure
Answer: 8
Answer:
The product of b and c is positive.
Step-by-step explanation:
b is negative as its less than 0
c is > 0 and is thus positive
multiply these would be negative result
