Answers: 0.08 and -0.08; 0.09i and -0.09i.
When taking square roots, we take the positive and negative answers. This gives us the first answer.
For the second answer, we rewrite -0.0081 as a complex number:
Even numbers on die: 2,4,6
odd numbers on die: 1,3,5
3+3=6 -> 6 numbers in total
3/6 chance because there are 3 even numbers. This would round to 1/2, so 1/2 a chance the die will roll an even number.

Answer:
x = 1
Step-by-step explanation:
Given
- 4y + 5x = 17 and (x - 3) is a solution
Substitute y = - 3 into the equation and solve for x
- 4(- 3) + 5x = 17
12 + 5x = 17 ( subtract 12 from both sides )
5x = 5 ( divide both sides by 5 )
x = 1
Solution is (1, - 3 )
