Answer: A. The rate of change of function A is -2. The rate of chance of function B is 4.
This is the A p e x answer
Answer:
4
Step-by-step explanation:
Hurley drank between 4 and 5 liters of water for 8 different days and drank between 1 or 2 liters of water on 4 different days. To find the answer we have to use the following equation.
# of days Hurley drank (4-5 L) - # of days Hurley drank (1-2 L) = # of more days
8 - 4 = 4
Answer
[$45 *for Mrs. Robert's perm*] + [2(8) *for each of her two childrens' cuts*] + [2(3) *since each of her kids had blow-drying and styling*]
Step-by-step explanation:
45 + 16 + 6 = 67 (total bill)
100-67 = 33 (Amount of change she should receive)
Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
![-2x+5y=19\\\\y=-\frac{5}{6}x-\frac{1}{6}\\\\\implies 6y=-5x-1\\\\](https://tex.z-dn.net/?f=-2x%2B5y%3D19%5C%5C%5C%5Cy%3D-%5Cfrac%7B5%7D%7B6%7Dx-%5Cfrac%7B1%7D%7B6%7D%5C%5C%5C%5C%5Cimplies%206y%3D-5x-1%5C%5C%5C%5C)
Now, we draw the graph :
According to question, solution point is (-3.2,2.5)
At this point, both the equations intersected at .
By Option 'C' we can see that
![(-\frac{13}{4},\frac{5}{2})\\\\=(-3.25,2.5)](https://tex.z-dn.net/?f=%28-%5Cfrac%7B13%7D%7B4%7D%2C%5Cfrac%7B5%7D%7B2%7D%29%5C%5C%5C%5C%3D%28-3.25%2C2.5%29)
and that is our required answer from the graph.
Hence, Option 'C' is correct.
