Answer:
The correct answer is option B
Step-by-step explanation:
The general form of inverse variation between the variables x and y is as following:
where c is constant
option A : y = x/12 ⇒ x = 12y (wrong option)
option B : y = 12/x ⇒ y * x = 12 (correct option) and c will be equal 12
option C : y = x + 12 ⇒ not similar to the general form (wrong option)
option D : y = 12x (wrong option)
So, the correct option is B
Answer:
Step-by-step explanation:
We need to solve for n.
Equation given is
We can add the values with n in the left side of the equation:
Then we can divide both sides by 46.
Now we can simplify the fraction by dividing numerator and denominator by 2.
Answer:
29
Step-by-step explanation:
it's arithmetic sequence.
it has a basic equation like this
Un = a + (n-1)d
a = U1 = first number in sequence
Un = number in n-th term
d = difference
U9 = 101 + (9-1)(-9)
U9 = 101 - 72
U9 = 29
so the 9th term is 29
For a line to be parallel, it must have the same slope as the first line so the slope of a parallel line would be -6.
Answer:
7/2
Step-by-step explanation:
12x=4(x+2)+20
12x=4x+8+20
12x-4x=8+20
8x=28
x=28/8
simplify
x=7/2
