What is the difference? 2x+5 3x+5 X+ 1
x² – 3x X² - gx x² g
(x+5)(x+2)
x² - gx
(x+5)(x+4)
x² - gx
-2x+ 11
x² – 12x-9
3(x+2)
x² – 3x

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
