Step-by-step explanation:
the dimension for the output isn't correct.
when u multiply 2x2 matrix by 2x1 matrix, the output matrix must have dimensions of 2x1
1. rational 2. irrational 3. irrational 4. rational
She should use 50% off.
964 divided by 1/2 = $482
964 - 400 = $564
I believe the answer is 5. I multiplied 5 to -4 and that’s -20 and I’m guessing since slope-intercept form is y=Mx+b I’m thinking b=4 and the slope being 5 matches the output. -16=5(-4)+4
