You could
create a equation such below:
y= 50x+20
Next, put
12 in both y=50x+20 and y=15x+80
Then,
y=50x+20=50 · 12+ 20=600+20= 620
y=15x+80=15 · 12+ 80=180+80= 260
Compare
these two, it's clearly that the second one is cheaper
Answer:
The camera in the second store is cheaper.
Slope intercept form is y=mx+b
59064 , since i multiplied them on a calculator
I believe it is x=55. I could be wrong lol
<span>difference of f squared and g = (f^2 - g)
</span>4 times the difference of f squared and g = 4 x (f^2 - g<span>)
</span><span>sum of f squared and 2g = (f^2 + 2g)
</span>4 times the difference of f squared and g, increased by the sum of f squared and 2g = 4 x (f^2 - g) + (f^2 + 2g<span>)</span>
