Answer:
Step-by-step explanation:
You really don't even have to calculate anything.
B can be reduced to 4/5 by dividing 24 by 6 and 30 by 6
C can be reduced to 1/15 by dividing 2 by 2 and 30 by 2
D can be reduced to 1/2.
The answer then is A
2 feet is 2 * 12 = 24 inches.
24/30 = 4/5. See B.
28.6 I think if it not I’m sorry
If you’re find the y-intercept the answer is: y=15
Answer:
x = -1/2
Step-by-step explanation:
This question can be solved by applying the laws of indices
In a^n, a - base
n - index
Given
9^x = 1/3
According to the laws of indices, a/b = b^(-a)
Hence we can write, 1/3 = 3^(-1)
9^x = 3^(2x)
Again according to the laws of indices,
a^b = a^n can be written as;
b = n
That is, if in an equation the bases are the same, the indices are also equal.
So we can write,
3^(2x) = 3^(-1)
2x = -1
Divide both sides of the equation by 2, the coefficient of x
2x/2 = -1/2
x = -1/2
