You have to substitute. So....


(-3,7): YES


y = -x + 4                              y = 1/3x + 8

7 = - -3 + 4                           7 = 1/3(-3) + 8

7 = 3 + 4                               7 = -1 + 8

7 = 7                                    7 = 7


(0,8): NO


y = -x + 4                              y = 1/3x + 8

8 = -0 + 4                             8 = 1/3(0) + 8

8 = 4                                     8 = 0 + 8

                                            8 = 8


(3,7): NO


y = -x + 4                              y = 1/3x + 8

7 = -3 + 4                              7 = 1/3(3) + 8

7 = 1                                      7 = 1 + 8

                                             7 = 9


(0,4): NO


y = -x + 4                              y = 1/3x + 8

4 = -0 + 4                             4 = 1/3(0) + 8

4 = 4                                     4 = 0 + 8

                                             4 = 8

Derek says that the quotient of -2/7 divided by -2/21 is -1/3. Part A: What is the correct quotient? Part B: What mistake did De
Thepotemich [5.8K]

Answer:

The correct quotient is 3.

I think Derek has mistaken to divide -\frac{2}{21} by \frac{2}{7}.

Step-by-step explanation:

We have to check the quotient of (-\frac{2}{7})  \textrm{ divided by }(-\frac{2}{21}).

Part A:

Now, (-\frac{2}{7})  \textrm{ divided by }(-\frac{2}{21}).

= \frac{-\frac{2}{7} }{-\frac{2}{21} } =3

So, the correct quotient is 3.

Part B:

Derek says that the quotient is -\frac{1}{3}.  

So, I think Derek has mistaken to divide -\frac{2}{21} by \frac{2}{7}. (Answer)

Dwayne is saving money so he can go to a professional soccer game. Dwayne has $10. He saves $15 a week
Lostsunrise [7]
The equation of the graph will be: y = 15x + 10
Where, x = number of weeks,

So, plot your graph there: (10,0), (25,1), (40,2), (55,3)

Take large scale for one axis which will represent the number of weeks.

Hope this helps!
