So this may not be correct but I tried so here’s my thought process

1. x - 2y = 3

2. 3x + 2y = 8

3. 2x + 3y = 13

4. 2x - 3y = 19

1. X = 9 Y = 3

2. X = 2 Y = 1

3. X = 2 Y = 3

4. X = 17 Y = 5

The question are vague enough to where anything can be put as x and y. These are just some of those results so do take this with a grain of salt. Good luck?

**Answer:**

**Maximum number of turns: 3**

**Step-by-step explanation:**

** **1. By definition, a polynomial of degree, has a maximum turning points of:

.

2. Therefore, if you have the polynomial given in the problem, which is a polynomial of degree 4 (), the maximum number of turns can be obtained as following:

3. Therefore, you can conclude that the maximum number of turns are 3.

**Answer:**

it would be 149s + 127v + 275f

**Step-by-step explanation:**

X represents her speed in miles per minute (b). To find her speed she would divide distance by time. If you divide 6.8 miles by 90 minutes and solve for x you will be finding her speed.
