The price of one share of XYZ inc's stock drop by $0.02 on Monday. On Tuesday the price goes back up by $0.05.
Vsevolod [243]

Answer:

1.<u> </u>$(x+0.03) - $x

2. $ 34.21

Step-by-step explanation:

Let the price of XYZ inc's share to be = <u>$ x</u>

On Monday, the price drops by $ 0.02 = $ x- $ 0.02 = $ (x-0.02)

New price of shares on Monday is =<u> $ (x- 0.02)</u>

On Tuesday the price goes up by $0.05 = $ (x-0.02) + $ 0.05 = $(x-0.02+0.05)

New price on Tuesday = <u>$( x+ 0.03)</u>..............................................(a)

Change in price of one share of XYZ's stock= Price on Tuesday - price of share

                                         = <u> $(x+0.03) - $x</u>..........................................(b)

2. Give that x= $34.18  solve equation (a) above

Price on Tuesday at close of business= $ (x+0.03)

                                                               = $ (34.18+0.03)

                                                                = $ 34.21

The table below shows how much Joe earns, y, after working x hours.
FromTheMoon [43]

Answer: Given : Joe’s Earnings and hour worked

The relationship between money earned and hours worked is linear.

Joe computes the slope between (4, 30) and (12, 90), then computes the slope between (4, 30) and (10, 75).

To Find : How do the two slopes compare?

Solution:

Hours worked     Money earned

4                          $30

10                        $75

12                        $90

22                       $165

slope between (4, 30) and (12, 90),

= (90 - 30)/(12 - 4)

= 60/8

= 15/2

slope between (4, 30) and (10, 75)

= (75 - 30)/(10-4)

= 45/6

= 15/2

The slope between (4, 30) and (12, 90) and between (4, 30) and (10, 75) is the same.

Both Slopes are same.

i hope this helped and have a nice day/night
