The first two rows of coefficients are identical, so by inspection, the determinant is 0.
You just have to look at the form of the equations
The only linear equations would be y = mx + b and Ax + By = C
Answer: 12 practice sessions
Step-by-step explanation:
You can represent the word problem in this equation: 200+50x<775 OR 200+50x=775
If you subtract 200 from 775, you’ll be left with: 50x=575
Count by fifties until you get to 575. You’ll notice that 50 doesn’t go into 575 evenly! However, this won’t matter, because Helga wants to make AT LEAST 775. So you can round up to 12 practices instead of 11, which will equal 800 dollars instead of 750.
