Answer:
![y=8(\frac{1}{2^x})](https://tex.z-dn.net/?f=y%3D8%28%5Cfrac%7B1%7D%7B2%5Ex%7D%29)
Step-by-step explanation:
Given is a graph which shows decrease in y when x increases.Marked in the I quadrant.
Coordinates in the graph are
(0,8),(1,4)(2,2)(3,1)
We find that for one unit change in x, there is 1/2 change in y
When x increases by 1 units y becomes y/2
So the equation is exponential
Equation satisfying all the coordinates can be written as
![y=8(\frac{1}{2^x})](https://tex.z-dn.net/?f=y%3D8%28%5Cfrac%7B1%7D%7B2%5Ex%7D%29)
Answer:
54°
Step-by-step explanation:
Opposite angles of a parallelogram are congruent, so;
![9x+9=8x+14 \\ \\ x=5 \\ \\ m\angle S=9(5)+9=54^{\circ}](https://tex.z-dn.net/?f=9x%2B9%3D8x%2B14%20%5C%5C%20%5C%5C%20x%3D5%20%5C%5C%20%5C%5C%20m%5Cangle%20S%3D9%285%29%2B9%3D54%5E%7B%5Ccirc%7D)
Next, solve as you would solve any two-step inequality. Since 2 is added to , you can get by itself on one side of the inequality by subtracting 2 from both sides. Then, to get by itself on one side of the inequality, you need to multiply both sides by 2.D
Answer:
$110.5
Step-by-step explanation:
48 + 25(2.5)
