14-8=6, so 8 balls balance with 6 balls and 20 grams. From this you know that 2 balls=20 grams, simply divide this by 2 to get the weight of one ball which will weigh 10 grams.

Okay so first to solve this lets set up our equation...

Devon has 14 balls of equal weight
14

8 of them go in one pan
14 - 8 = 6

6 goes in another pan along with a weight of 20 grams

So if we assume each ball is 10 grams then the 6 plus 20 grams would equal 8 balls.

This would balance it out.

8 balls of 10g - 6 balls of 10g and a 20g weight

So each ball would weigh 10 grams

Hope this helped. Have a great night!

ANSWER

The maximum y-value is 0.

EXPLANATION

The domain of the given absolute value function is (-∞, ∞) .

This means the function is defined for all real values of x.

The range of the function is (-∞, 0].

This can be rewritten as

y \leqslant 0

This means that, the highest y-value on the gray of this absolute value function is 0.

Hence the maximum y-value of the function is 0.

Let f(x)=100−10+e−0.1x .
lianna [129]
What are you solving for?
If you are solving for × then I hope this helps

Let's solve for x.

f(x)= 100−10+e−0.1x

Step 1: Add 0.1x to both sides.

xf+0.1x=−0.1x+e+90+0.1x

xf+0.1x = e+90

Step 2: Factor out variable x.

x(f+0.1) = e+90

Step 3: Divide both sides by f+0.1.

x(f+0.1)/ f+0.1 =e+90/ f+0.1

x=e+90/ f+0.1

Answer:

x= e+90/ f+0.1
