The equations y = 30x + 10 and y = –x2 + 150x + 10 model the daily sales of two car models, where x represents the number of day

yuradex [85]

Answer:

day 0, day 120

Step-by-step explanation:

You want to find the value of x that makes both y-values be the same:

y = y

30x +10 = -x^2 +150x +10

x^2-120x = 0 . . . . subtract the right side of the equation

x(x -120) = 0 . . . . . factor

Values of x that make this true are x=0 and x=120.

The same number of each car was sold on day 0 and day 120.

Answer:

First option $6^\frac{1}{6}$ is the correct answer.

Step-by-step explanation:

Let us consider each part, we have number 6 inside all the roots.

First we have to find cube root of 6.

$\sqrt[3]{6} =6^\frac{1}{3}$

Now we have to find square root of this value.

$\sqrt{6^\frac{1}{3} } =(6^\frac{1}{3} )^\frac{1}{2} =6^\frac{1}{6}$

So, first option $6^\frac{1}{6}$ is the correct answer.
