Slope is -1/4 and the y intercept is -1.5
Answer:
1: 3 dimes & 8 nickles
2: 17 & 8
3: can't do 3, i'm sorry but you have to do it
4: y = 2x+2 y = -1/3x + 6
5: no bc the only part of the system that that point is on is the first equation, 2x-y=1.
have a nice day :)
(3x+5i)(3x-5i)
9x^2+25
=(3x)^2 + (5)^2
=(3x+5i)(3x-5i)
