Answer:
So the union of sets A and B is the set of elements in A, or B, or both. The symbol is a special "U" like this: ∪ Example: Soccer = {alex, hunter, casey, drew}
Step-by-step explanation:
Answer:
2nd option: 2y=6x+8 and y=3x+4
Step-by-step explanation:
If you divide the first by 2, you get the second equation.
This means that both equations plot an identical line (they lie on top of each other /also known as "coincide"). This means, that there are infinitely many solutions.
In 2D (x-y plane for example), straight lines can have no solutions if they have the same gradient/slope/ they are parallel and different y-intercepts, because they will never cross.
Here, they have same gradient and y-intercept so all points on the line are valid solutions to the equation
Answer:
C
Step-by-step explanation:
Answer:
C would be the answer to the first part because the two subtractions is a double negative making it a positve so if you replace that with a addition symbol it will read the absolute value of 125+70 which is 195
Part two the distance is 195 which is found in the first part. Absolute value is the distance from 0.
Part 1. C
Part 2. D
Hope this helps
