80 grams of butter
Step-by-step explanation:
640/2=329
3x320=960
960-880=80
Answer:
First, we need to know when the function is increasing, and when is decreasing.
When a function is increasing, it's because to higher <em>x-values </em>belong higher <em>y-values. </em>On the other hand, a function is decreasing when to higher <em>x-values </em>belong lower <em>y-values. </em>The effect in the graph will be a upwards direction of the function when is increasing, and a downwards direction when is decreasing.
So, according to the given graph, we see that between 0 and 4 is increasing, the higher x-values are, higher y-values are. Between 4 and 6 is decreasing, is downwards. Between 6 and 8 is increasing. Between 8 and 10 is decreasing. In finally, between 10 and 14 is neither decreasing or increasing, it remains horizontal.
All these interpretations we can expressed using math language, specifically inequalities:
- 0 < x < 4: increasing.
- 4 < x < 6: decreasing.
- 6 < x < 8: increasing.
- 8 < x < 10: decreasing.
- 10 < x < 14: neither increasing or decreasing.
Step-by-step explanation:
Ariana and Mackenzie exercised for 20 minutes more than Brinley and Seth.
x = Seth exercise minutes
Ariana minutes = 3x
Brinley minutes = 3x - 17
Mackenzie minutes = 1/2 × (3x - 17)
so, in total we have
3x + ½(3x - 17) = x + (3x - 17) + 20
statement 1 is true.
6x + (3x - 17) = 2x + 2(3x - 17) + 40
6x + 3x - 17 = 2x + 6x - 34 + 40
9x - 17 = 8x + 6
x = 23
statement 2 is false.
Brinley and Seth exercised together for
x + 3x - 17 = 23 + 3×23 - 17 = 4×23 - 17 = 75 minutes
statement 3 is false.
Mackenzie exercised for
½(3x - 17) = ½(3×23 - 17) = ½(69 - 17) = ½×52 = 26 minutes
statement 4 is true.
