A curve divides a plane into two areas, one satisfying the inequality (shaded) and one that does not (unshaded). So we can pick a point on either side (not on the curve itself) and substitute its x- and y-coordinates into the inequality. If the substituted values make the inequality true, then that point is in the shaded area. Otherwise, that point is in the unshaded area.
Answer:
ratio of regular to diet soda = 16/9
Step-by-step explanation:
Jessica brought a cooler to the family picnic filled with 32 cans of regular soda and 18 cans of diet soda. This means
Number of cans of regular soda = 32
Number of cans of diet soda = 18
Total number of soda brought to the family picnic = number of cans of regular soda + number of cans of diet soda
= 32 + 18= 50
the ratio of regular soda cans to diet cans in the cooler= 32/18
Divide numerator and demo minator by 2, we have 16/9.
The fraction cannot be reduced further. So ration of regular to diet soda = 16/9
X - 2y = - 9
7x + 2y = 1
x - 2y = - 9
(+)
7x + 2y = 1
___________
8x = - 8
x = - 1
- 1 - 2y = - 9
2y = 8
y = 4
