X + 2y = 1 ______×1
4x + y = 11 _____ ×2
x + 2y = 1
8x + 2y = 22
8x + 2y = 22
(-)
x + 2y = 1
_____________
7x = 21

y = 1
i am a mathematics teacher. if anything to ask please pm me
-3 > x
The values that make this inequality true are those that are less than -3. The inequality does not include -3.

The complete question is in the attached file. So we have to choose between two graphs. On of them is a linear model while the other is an exponential model. From the statements, we have a relationship between time and the number of teams registered. So we can establishes variables in the following form:

We also know that each week 6 teams register to participate, so:

As you can see, as x increases one week, y increases at a constant ratio of 6. Therefore, this can be modeled by a linear function given by the form:

In conclusion, <em>the linear model (first graph below) is the one that bests represents the relationship between time and the number of teams registered.</em>
Answer:
x = 45
Step-by-step explanation:
Re-order terms so constants are on the left
15 * x/9 - 42 =28
Combine multiplied terms into a single fraction
15x/9 - 42 = 28
Cancel terms that are in both the numerator and denominator
5x/3 - 42 = 28
