Answer:

14x² + 7y - 22

Step-by-step explanation:

Combine like terms.

5x² - 6y - 22 + 13y + 9x²

5x² + 9x² = 14x²

-6y + 13y = 7y

Reorder the terms.

14x² + 7y - 22

Hope that helps.

a recipe for cookies calls for 10 1/6 cups of sugar. krystal has already put in 4 2/3 cups. how many more cups does she need to
DENIUS [597]

Answer:

5 1/2 cups

Step-by-step explanation:

10 1/6 = \frac{61}{6} cups

10 x 6 + 1

\frac{61}{6}

4 2/3 = \frac{14}{3} cups

4 x 3 + 2

\frac{14}{3}

Find a common denominator (6)

\frac{14}{3} = \frac{28}{6}

\frac{14}{3} · 2 = \frac{28}{6}

\frac{61}{6} - \frac{28}{6} = \frac{33}{6}

\frac{33}{6} or 5 1/2 cups

Hi,

The answer to your question is either A or B. 

The y-intercept is at point (0,60). All the other options (C and D) do not make sense and just aren't logically. 

The y-intercept (0,60) literally shows that if a student studies 0 hours they can expect to score a 60 on the test. 

Thus, you're answer is option B.
