Given:
Discount = 40%
Sales tax = 7%
To find:
The total cost of levi jeans with an original price of x.
Solution:
Let x be the original price of the jeans. Then the price after 40% discount is
The price after 7% of sales tax.
Therefore, the total cost of the levi jeans with an original price of x is represented by the expression 0.642x.
This is it if you want it written as an equation:
n - 16
Do PEMDAS! Multiply and divide from left to right. 123456789 x 125 is 15432098625, and now we divide by 4, giving us 3858024656.25, but rounded to the nearest whole number (ones) is 3858024656.
Hope this helped!

Let's first calculate the roots of f(x) = x³-18x²+101x-180
a) f(4) = 4³ - 18.(4²) +101.(4) -180 =0, then x=4 is a root.
b) to find the 2 other roots divide x³-18x²+101x-180 by (x-4) = x²-14x+45
c) this quadratic equation has the following roots: x=5 and x=9. Hence:
f(x) = x³-18x²+101x-180 = (x-4)(x-5)(x-9)
the x-intercepts are x₁ = 4, x₂ = 5, x₃ = 9.
To find the y intercept plug x= 0 in f(x) = x³-18x²+101x-180
f(x) = y = -180 (y intercept
