I know for sure A is true. How to solve: f(-3) basically means, what is the output value when x=-3? In this case, when x=-3, the output is indeed, 2.

I really don't think you wrote the question properly. Or maybe you did, but this question doesn't make any sense! :/

The royal fruit company produces two types of fruit drinks the first type is 70% pure fruit juice and the second type is 95% pur

Ipatiy [6.2K]

This is a typical mixture problem where using a table is the best thing.
pints juice % juice = total % juice
juice A x .70 = .70x
juice B 60-x .95 = .95(60-x)
total 60 .75 = 60(.75)

The last row gives you a total that you need to use, so do that multiplication to get 45. You now to need to add the last columns together for rows 1 and 2 and set them equal to 45: .7x +.95(60-x) = 45. When you do that math, you'll get that x = 48. This means that you need 48 pints of juice A and 60-48 pints of juice B, which is 12 pints.

Julia bought stock at $281/8 per share. The value of each share increased by $65/8. How much is each share of stock now worth?

The worth of the share of stock is $ $34\frac{3}{4}$ .

<h3>What is the worth of the stock now?</h3>

A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below.

A mixed fraction is a fraction that is made up of a whole number and a proper fraction. A proper fraction is a number where the numerator is less than the denominator.

The worth of the stock now = purchase price + increase in the share price

28 1/8 + 6 5/8

$34 \frac{1 + 5}{8}$
