Please write this equation as    <span>f(x) = −18 + x^2 − 3x       

Rewrite it in descending order by powers of x:  f(x) = x^2 - 3x - 18

Since the coefficient of the x^2 term is +, the graph opens UP.</span>

There are 110 calories in 8 ounces of gape juice. How many calories are in 10 ounces of grape juice?
daser333 [38]
In order to solve this problem, we need to set up a proportion.  I am setting the amount of calories in 10 ounces of grape juice equal to x.

\frac{110}{8} = \frac{x}{10}

We begin to solve this by cross multiplying.

8x = 1,100

To finish the problem, we divide both sides by 8.

x = 137.5, so the 10 ounce glass of grape juice will have 137.5 calories.
