Answer:
12% of the price of a bike is $64.8.
100% of the price of a bike is a.
We have 64.8/a = 12/100
=> a = 64.8 x 100/12 = 540$
=> Price of the bike: 540$
Hope this helps!

J(x) is equivalent to Y. For example if you were to have a equation in slope intercept form it would be y=mx+b which can be written in the same way as your problem j(x)=mx+b. To sum it up j(x) is just another way to say y=
Answer:
i think it's the third one
First thing to do is to solve each of these for y. The first one is y=-4x-3; the second one is y=4x-21; the third one is y=4x+21; the fourth one is y=-4x+3. From that you can tell the positive slopes are found in the second and third equations. Those are the ones we will test now for the point (3, -9). y=-9 and x=3, so let's fill in accordingly. The second equation filled in is -9=4(3)-21. Does the left side equal the right when we do the math? -9=12-21 and -9=-9. So the second one works. Just for the sake of completion, let's do the same with the third: -9=4(3)+21. Does -9=12+21? Of course it doesn't. Our equation is the second one above, y+9=4(x-3).
