3(3) - (-8)/4 = 9 + 2 = 11 so (3,-8) is solution
3(4) - 4/4 = 12 - 1 = 11 so (4,4) is solution
answer

Answer:
The most likely answer would be 282,240.
Step-by-step explanation:
I got a different value than the choices you've given me. But if 282,240; 14; and 21 are your only options, then the most likely answer would be 282,240. Any number followed by an exclamation point means that it will be multiplied by all whole numbers from 1 to that number. For example, 4! would be 1 * 2 * 3 * 4 = 24. In this problem, 7! equals 5,040; 8! equals 40,320; = ; and 9! = 362,880. You can tell by the listed numbers that the product will be extremely big despite the fraction, so the best choice to go with would be 282,240.
Answer:
Mark has the correct answer. Ryan and Jessica both made mistakes in their calculations with computing negative integers.
Step-by-step explanation:
Looking at the graphing method first, we need to get both equations into the slope-intercept format (y = mx + b) to compare these variables:
y = 3x + 2 has a slope = 3 and y-intercept = 2
6x - 2y = 10 can also be written as -2y = -6x + 10 or y = 3x - 5 which also has a slope = 3, but a y-intercept = -5
Since both lines have the same slope, then we know they must be parallel and therefor, there is no solution.
Ryan used elimination to solve his system, however, when converting both equations to standard form (Ax + By = C), he forgot to make the '3x' from the first equation negative, or '-3x', which made the rest of his calculations incorrect.
Jessica used matrices and made the determinant for the system, x and y. Jessica set up her determinant correctly, however, when solving the system determinant, she did not multiply 3 x -2 correctly and instead put positive 6 instead of -6 which made her answer 12 instead of 0.
