Standard form (which I assume is what they want you to turn these into) is y=mx+b.
12x-5y=20 is y=2.4x-4.
Subtract 12x from both sides, -5y=-12x+20.
Multiply both sides by -1, 5y=12x-20.
Divide both sides by 5, y=2.4x-4.
y=x+4 is already in standard form- I'm not quite sure what to do.
3x+y=3 is y=-3x+3.
Subtract 3x from both sides, y=-3x+3.
x=-y+3 is y=-x+3
Ad y to both sides, y+x=3.
Subtract x from both sides, y=-x+3.
The answer is D, none of these
9w+45= amount of money she’ll have after any amount of weeks.
So, since W is weeks... and you have 9 weeks, you do (9x9)+45.
Then you get 81+45, which is 126. She will have $126 after 9 weeks

Answer:
option A is answer.
Step-by-step explanation:
Amount of interest earned for compounded monthly for $1 = 1.040742
Amount of interest earned for compounded quarterly for $1= 1.040604
Difference for $1 = 1.040742 - 1.40604
=0.000138
Difference for $7000 = $7000x0.000138
= 0.966
or $0.96
