Brightness 5 ohm, battery drain 10 ohm

I disagree. Assuming that the bulbs are not connected together in either series or parallel, the answer is the five ohm resistor. The five ohm resistor passes twice as much current as the ten ohm.

The bulb with 10 ohm resistance will grow brighter and the same bulb will diffuse first

slope or m = (y2 -y1)/(x2-x1)

always start with the same point.

m = (1 - (-5))/(-2-5)

m = (1 + 5)/(-7)

m = 6/-7

m = -6/7

The y-intercept is the b in the equation y=mx+b.

We can use either point to calculate b. Let's use (-2,1). So every time we see x, we put in -2, and every time we see y, we put in 1.

y = -6/7x + b

1 = -6/7 (-2) + b

1 = 12/7 + b

1 = 1 5/7 + b

-5/7 = b

So, y = -6/7x - 5/7

To check, we substitute in the other point and see if the left side is equal to the right side.

LS RS

-5 -6/7(5) - 5/7

-5 -30/7 - 5/7

-5 -35/7

-5 -5

LS = RS

Good luck,

a^2 + b^2 = c^2

a squared + b squared = c squared, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides in a right-angled triangle.

I would say that the answer would be 11!/2

Let's look at the overall picture. Does it make sense if you have a fifth of a pizza and add a half pizza, you get less than a third of a pizza.

Now, into the math.

Here is a fifth of a pizza.

Here is half a pizza.

It is hard to add these two.

We find the least common multiple of the denominators 2 and 5 and get 10.

Let's redo the pizzas in 10 slices.

And the half pizza.

Now with the same sized slices, we can add the slices and calculate the result.

Now we have seven slices out of ten, or 7/10.

Good luck.
