Answer:

8 1/2 hrs/wk

Step-by-step explanation:

3(1 1/2 hrs) plus

2(1 1/4 hrs) plus

2(3/4 hr)

The LCD here is 4.  Convert 3(1 1/2 hrs) to 3(1 2/4 hrs), so that we now have:

3(1 2/4 hrs)  = 3 6/4 hrs

+2(1 1/4 hrs)  =  2 2/4 hrs

+2(3/4 hrs)   =       6/4 hrs

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

                          5 14/4 hrs, or

                          5 + 3 2/4 hrs, or

                              8 1/2 hours/week

Answer:

9. Perpendicular

10. neither

11. Perpendicular

12. neither

Step-by-step explanation:

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

Slope Intercept Form: y = mx + b

* M is the slope

* B is the y intercept

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

Lines are parallel if they have the same slope (ex. If two equations have a slope of 2)

Lines are perpendicular if they have the opposite and the reciprocal slope (ex. If 1 equation has a slope of 3 and another equation has a slope of - \frac{1}{3} )

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

9. Perpendicular: The slopes are reciprocal of each other and one of them is negative

10. Neither: The lines are not perpendicular because the slopes are both negative

11. Perpendicular: If you plot y=5 it is a horizontal line through 5. If you plot x=-3 it is vertical line through -3. These lines intercept and are perpendicular.

12. Neither: The slopes of both equations need to be the same to be parallel

  • Put both equations into y=mx+b
  • y = 1/2x -2 AND y = -1/2x -2

To make a small vase, Elisa uses no more than 4.5 ounces of clay. To make a large vase, she uses at least 12 ounces of clay. Whi
Sveta_85 [38]

Answer: d. 4.5\leq c\text{ or }x\leq12

Step-by-step explanation:

Let the number of ounces of clay that Elisa uses to make one vase of either size denotes by 'c'

Given : To make a small vase, Elisa uses no more than 4.5 ounces of clay.

i.e. 4.5\leq c

Also, To make a large vase, she uses at least 12 ounces of clay.

i.e. c\leq12

Then , the compound inequality represents the number of ounces of clay that Elisa uses to make one vase of either size will be :-

4.5\leq c\text{ or }c\leq12

UkoKoshka [18]
Total miles= rate x time

We can set up 2 eq:
24=(x+8)(y-4)
24=xy

Where x is equal to my original rate
and y is equal to the original time spent traveling the 2mi

We can now solve for one of the variables and find our rate
