(-1,-9) because if we substituted 1 into x y would be 9 and if we substituted 1/2 into x y would be 3 but if we substituted -1 into x y would be 1/9 so therefore that value is incorrect
Answer:
i think its d
Step-by-step explanation:
Answer:
first one: 8
second one: 3
Step-by-step explanation:
-3x + y = -24 |÷(-3x)
y = 8
y = 7x + 22 |-y
(y would be 1; the 7x moves to the other side.) meams:
7x = 21 |÷7
x = 3
Answer:
0.51 or 51%.
Step-by-step explanation:
If there were 100 students in the school, then 38 have a dog 24 a cat and 11 have both.
So there are 38 - 11 = 27 who only have a dog and 24-11 = 13 who only have a cat.
So total number having a pet = 27+11+13
= 51 students.
So Prob(You will choose a student with a pet) = 51%.
Drawing a Venn diagram would help to answer this and make it clearer.
