Step-by-step explanation:
The input value at which f(x) = g(x) can be found by setting the right sides of each of those equal to each other and solving for x.
1.8x - 10 = -4 and
1.8x = 6 so
x = 3 1/3
The bold equation is the answer to the first part, and the second part is that x = 3 1/3
Answer:50 x 2 = 100.
100 ÷ 5 = $20 off.
50 – 20 = $30 sale price.The sale price is $30.
The equation of this parabola will have the form f(x) = a(x+5)(x-4), which works out to f(x) = a(x^2 + x - 20). Since the parabola passes thru (3,40),
40 = a(3^2 + 3 - 20), or 40 = a(-8), so a = -5.
Thus, the equation of this parabola is y = -5(x^2 + x - 20).
It is not because it is a whole number fractions are mixed numbers
