I really, really don't like this question. People have preferences in solving quadratics. I would personally use, and would encourage anyone to use the quadratic equation. That's because completing the square would get excessively fractional, graphically doesn't even work because the solutions are imaginary, and differentiating it wouldn't be necessary, as there are no irrational numbers (except i, which is just imaginary). So, in short, quadratic equation because you can't get anything graphically, the answers are ugly fractions, and you can actually use that method.
- 9 and - 3
consider 3 units to the left and right of - 6
- 6 - 3 = - 9 ( 3 units to the left of - 6 )
- 6 + 3 = - 3 ( 3 units to the right of - 6 )
Step-by-step explanation:
write a formula that models this.
9.30x = money earned
If he works 2 hours, he'll get $9.30 times (2)
and so on. so you write and solve
9.30(1), 9.30(5), 9.30(8)
for the second part you want to substitute 180 for the amount earned which will become
9.30x = 180 then you solve for x
Ratios equivalent to 4:3 would be 8:6 16:12 and 24:18
Answer:
The answer is

Remember that Taylor says that
For this case
