Answer:
(D) xy/(x + y)
Step-by-step explanation:
To find r in terms of x and y
Given,
- two resistors with resistances x and y are connected in parallel
- r is the combined resistance of these two resistors
- the reciprocal of r is equal to the sum of the reciprocals of x and y
Then,
1/r = 1/x + 1/y
1/r = (y + x)/xy
Find the reciprocal of both sides
r = xy/(x + y)
The right answer is option (D) xy/(x + y)
Answer:
These Lines will be parallel.
Step-by-step explanation:
You have to find the slope of each line. For (1,1) and (3,3) the slope is 1 and for Line 2 the slope is also 1. (let me know if you want me to show the work for slope). To have parallel lines the slopes have to be the same and y-ints have to be different. Here the slopes are the same and in Line 1 the yint is (0,0) which is different than Line 2. Therefor the Lines are parallel.
Sorry if im wrong!. Hope this helps
Answer:
b = -6
Step-by-step explanation:
Apply the exponent rule that
In this case,
Set that equal to :
Apply the exponent rule that so now you get:
Since the base is y for both sides of the equation, just set the exponents equal to each other and solve for b.
4b = -24
divide each side by 4 to get:
b = -6
