Answer:
no
Step-by-step explanation:
2x + 3y ≥ 20
Substitute the point (2,5) in for x and y and see the inequality is true
2(2) +3(5) ≥ 20
4 + 15 ≥ 20
19 ≥ 20
This is not true, so (2,5) is not a solution
Answer:
D
Step-by-step explanation:
Using process of elimination we know that it cannot be a,b or c because after you add the 2 new stamps james collected the ratio is 8:12 which cannot be 1:2 because 8 is not half, can't be B because 8 is less than 12, Also cannot be C because 8 is less than 12
Remember.
positive number x positive number = positive number
positive number x negative number = negative number
negative number x positive number = negative number
negative number x negative number = positive number
So if both numbers have the same sign, either both positive or both negative, then the product will be positive.
21.3 is the correct answer.
