(- 2, - 3) is a solution to the given system of equations.
Answer: Option D
<u>Step-by-step explanation:</u>
Given equation are not presented in proper format. So, let assume the given system of are as below,
2 x - y = -1
2 x -4 y = 8
Now, subtract the second equation from the first, we get
(2 x - y) -(2 x - 4 y) = -1 -8
3 y = -9
y = -3 (obtained this when divide by 3)
Substituting y = - 3 into the first equation, we get
2 x - (-3) = - 1
2 x = - 1 + 3
x = - 2 (obtained when divide by 2)
Now, the answer is (x, y) = (- 2, - 3)
¹/24
Step-by-step explanation:
The number of favorable outcomes (rolling a 5) is 3
The total number of possible outcomes is 12 * 6 = 72
Therefore;
P(5) = 3/72
= 1/24
Answer:
To form the contrapositive of the conditional statement, interchange the hypothesis and the conclusion of the inverse statement. The contrapositive of "If it rains, then they cancel school" is "If they do not cancel school, then it does not rain."

Answer:
Step-by-step explanation:
b must not be an even number
2a>b
a+b>a
so b could be 3.1, 3.3, ......7.7
