Question

what is the absolute value of |3x+9|-12=-8

Answer 1

do you need both answers or just one

Answer 2

both answers, negative and positive

Answer 3

ok just a sec

Answer 4

can your ansers be decimals

Answer 5

yes

Answer 6

ok then |3x+9|-12=-8 is x=-1.6 and |3x+9|-12=8 is x=-4.3

Answer 7

can you help me with the bio question i sent you

Answer 8

i was hoping that i would see a negative and a positive answer including the steps to how you arrived at that answer

Answer 9

because my lecturer stated that the inequality absolute values answers are to be negative and positive and not positive and positive or negative and negative.

Answer 10

O sure, i will respond to your biology question just give me a few minutes to organize the words

Answer 11

well when i set up the problem ( i did it on paper) i set the two problems up as one positive and one negative and then solved and those were the answers

Answer 12

i believe you, i have been working the question on paper since sunday and i kept getting both negative answers

Answer 13

would you like me to answer you Biology question here?

Answer 14

sure if the is easiest for you

Answer 15

hello?

Answer 16

are you there

Answer 17

The water and minerals enter the plant from the growth medium through the root hairs, then pass into the Xylem Vessels. These are tubes which have thickened walls and woody tissue with small holes or are arranged in rings. The Xylem is part of a system of tubes in vascular(vessel-like) bundles or veins and lies towards the inside, while the other tube-the phloem- lies to the outside of the vascular bundle. Phloem consists mainly of sieve tubes which are separated from each other by areas with perforations or holes, much like a sieve. It is the role of the phloem to provide the pathway for manufactured foods from the leaves, to other parts of the plant. The food provides energy by respiration, promotes growth in stored organs such as roots and stems as well as fruits and seeds. Root hairs which are really outgrowths of the epidermal(or outer-most) layer of the root, have a semi-permeable cell membrane. If there is a higher concentration of water in the growth medium of the plant, water can enter the plant through it. This occurs because there is a difference in concentration, and movement of water occurs along its diffusion gradient. Remember that Osmosis is the special type of diffusion of water from an area of high concentration(plenty) to an area of low concentration(small amount) of water. The movement of water b osmosis continues across the layers of root cells and then enters the Xylem to be transported up the stem to the leaves. Minerals which are dissolved in the water may also enter the plant through root hairs. However, the concentration of some salts may be higher in the root cells than in the growth medium. In order for slats to be absorbed by the plants, energy has to be expended to move the salt from a low to a high concentration, against their gradients. This process is known as active transport or active uptake. The movement of oxygen, carbon dioxide, and water vapour occur by diffusion. Having passed through the root of the plant, water(and dissolved minerals) must be taken up the plant through the stem to the leaves via the xylem vessels. Because the tubes are very narrow the water tends to rise by a mechanism called Capillarity. If you use Capillary tubes in the laboratory, you will know that they have a very small internal diameter and water tends to rise to a higher level in them than in those of wider diameter. In addition, the xylem vessels have a continuous stream or flow of water from the root, through the stem to the leaves. As water is lost by transpiration, a kind of vacuum is created so that more water is drawn up from the xylem to replace that which is lost. The water is being 'pulled up' through the plant and this mechanism is called transpiration pull. There is also another force called root pressure or root push which occurs as water enters the roots.
