I can’t see A-c can u take another picture
Hello! So in order to solve this problem, it's best to start off making an equation. $18 + $.15x = $29.25
In this equation x represents the number of minutes she used. So now, we just have to solve for x.
First subtract $18 from both sides. Your new equation will be $.15x = $11.25. Then divide both sides by $.15 to get x by itself. $11.25/$.15 = 75.
So we can conclude that Bella spoke on the phone for 75 minutes this last month. Hope this helps!
Rule: second differences are 2.
Selection C is appropriate.
_____
First differences are the sequence of differences of the given numbers:
.. 3 -8 = -5
.. 0 -3 = -3
.. -1 -0 = -1
.. 0 -(-1) = 1
Second differences are the sequence of differences of these:
.. -3 -(-5) = 2
.. -1 -(-3) = 2
.. 1 -(-1) = 2
All of these are 2, so the sequence can be described by a *second* order polynomial (because *second* differences are a non-zero constant).
Answer:
Most Likely C) y = -8x + 75
Step-by-step explanation:
- The scatter plot shows a negative association, so the line of best fit has a negative slope. The eliminates A and B, since their slopes are positive.
- The highest point is (0,75). Because of this, it is safe to assume that would be the best estimate of the y-intercept.
- Out best answer is
Answer:
107
Step-by-step explanation:
180 -73 is 107 hope that helps
