(x+12)(x-3) Try this answer hopefully it is correct.
The bike will cost $481.50
because
10% off of 500 is 50
so 500 - 50 = 450
Now include the sales tax which is
450 * 0.07 = 31.5
Now add the two totals to get
$481.50
Answer:
(7x9)x10 the power of 3 is 63,000
Using sin(A+B) = sinAcosB + cosAsinB
sin20cos40 + cos20sin40 = sin(20+40) = sin60degree
=
Answer:

Step-by-step explanation:
So the point-slope formula looks like this: 
= any y point on the line
= any x point on the line
= the slope
And hey, look, we're already given all that information!
So we can just plug those values into the equation:

(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)
