he first three steps in determining the solution set of the system of equations, y = –x2 – 2x + 8 and y = 2x + 11, algebraically

ivann1987 [24]

Answer:

The solutions are -3 and -1

Step-by-step explanation:

∵ y = -x² - 2x + 8

∵ y = 2x + 11

∴ -x² - 2x + 8 = 2x + 11

∴ -x² - 2x - 2x + 8 - 11 = 0

∴ -x² - 4x - 3 = 0 ⇒ divide both sides by -1

∴ x² + 4x + 3 = 0

∴ (x + 3)(x + 1) = 0

∴ x + 3 = 0 ⇒ x = -3

∴ x + 1 = 0 ⇒ x = -1

∴ The solutions are -3 and -1

22 fl oz=how many cups and fl oz

igomit [66]

1 cup = 8 fl oz.

So then we can set up a ratio of $\sf \frac{fluid ~ounces}{cups}$

So we get:

$\sf\frac{8~ fl. oz.}{1 ~cup} = \frac{22 ~fl. oz.}{x~ cups}$

We cross multiply and we try to solve for x, so:

$\sf 8~fl.~oz. \times x ~cups = 1~cup \times 22~fl.~oz.$

$\sf x~cups = \frac{22~fl.oz.}{8~fl.oz.}$

And the fl. oz. cancel out, and we are left with:

$\sf x~cups = \frac{22}{8} = \frac{11}{4} = 2 \frac{3}{4}$

<u>So 22 fl. oz. equals to 2 3/4 cups.</u>
