Part C of Jim and his dad are building a rectangular flower bed.
charle [14.2K]
I gotchu

The perimeter is 35. If we were to change the width, which is one of the dimensions of the flower bed, The perimeter will change. This means that perimeter will no longer be 35. So in order to keep the perimeter as it is, if we change one dimension, we must also change the other.

Let's solve for the length, using the formula to see how much the length changes from.

p = 2l + 2w

35 = 2l + 2(15)

35 = 2l + 30

5 = 2l

2.5 = l


We must increase the length from 2.5 feet. This is because decreasing one dimension will decrease the perimeter. But if we increase the other dimension as well, it will restore the perimeter to where is was initially.

HELP WILL MARK AS BRAINLIST
Alinara [238K]

Hi!

Given:

\frac{x}{-1} > -6

Multiply both sides by -1

x

<em>Notice the sign was flipped. This is because when you multiply or divide by a negative number, you must always flip the sign!</em>

<u>Now, for the graph:</u>

-------------------------------------------------------------------------------------------------------------

For < or > signs, it should be an open circle. For \leq or \geq signs, it should be closed.

Since x is less than 6, it should go to the left. Since it's a < symbol, it should be open. Therefore your answer is B.

(looks like you were right!!)
