x + 4x = 05x = 0x = 0/5x = 0
5x + (4 - 4x) = 05x + 4 - 4x = 0x + 4 = 0Subtract 4 from each side:x = -4
y = 5x + 6At the x-intercept, y = 0 .5x + 6 = 05x = -6x = -6/5

Oh, dude, you're hitting me with some math right now? Okay, so to find what times 5 percent equals 16000, you just divide 16000 by 0.05. That gives you 320,000. So, 320,000 times 5 percent equals 16000. Easy peasy, right?
y = 5x + 6At the x-intercept, y = 0 .5x + 6 = 05x = -6x = -6/5
5x2 - x - 4 = 0(5x + 4) (x - 1) = 05x + 4 = 05x = -4 ===> x = -(4/5)x - 1 = 0 ==> x = 1
Let X be the original price .05X = first discount new price is X-.05X .20(X-.05X) = 2nd discount new price is X -.05X - .20(X-.05X) new price = X - .05X -.20X + .01X = X - .24X equiv discount = .24 = 24%

5x^2 + 40x = 05x(x + 8) = 05x = 0 or x + 8 = 0x = 0 or x = -8Check:
.05x=7474/.05 = xx = 1480100% is 1480, 1/15 is 6.6666% so 6.666% of 1480 = 98.66698.6666
