Hello, I need help understanding this problem.

Step-by-step explanation:

Given points M( -5 , 9) and N( -2 , 7)

Now mid point of MN

(x, y) =

= {(-5-2)/2 , (9 +7)/2}

= (-7/2 , 8)

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
