y=5x-13

Step-by-step explanation:

y=mx+b     is point slope form

2=-3(-5)+ b             Plug in to find b

2=15+b                  simiplify

13=b                       subtract 15 from both sides

y=5x-13           plug into equation

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
