Answer:

The answer is 12 ounces.

Step-by-step explanation:

In order to determine the answer, we have to know about directly proportional.

A directly proportional is when two variables are increased at the same time. Both variables have a relation, expressed by a fraction. The fraction is called "constant of proportionality".

In this case, we have:

\frac{oil}{gasoline}=\frac{6}{16}=\frac{3}{8}

We always have to fulfil this relation.

Thus, for x: ounces of oil for 32 gallons of gasoline.

\frac{x}{32}=\frac{3}{8}\\  \\x=\frac{3*32}{8} \\x=12

Finally, the amount of oil for 32 gallons of gasoline is 12 ounces.

Write the equation of the line passing through the point (-4 "-7)" and (8 "-17)"
kicyunya [14]

Answer:

y  = -\dfrac{5}{6} x -\dfrac{31}{3}

In order to find equation:

<u>Find slope</u>:

\sf  slope: \dfrac{y_2 - y_1}{x_2- x_1}  = \dfrac{rise}{run}

\rightarrow \sf slope:  \dfrac{-17-(-7)}{8-(-4)}

\rightarrow \sf  slope: -\dfrac{5}{6}

Then find equation using:

y - y1 = m(x -x1) where (x1, y1) are points, m is slope

\sf \rightarrow y - (-17) = -\dfrac{5}{6} (x - 8)

\sf \rightarrow y  = -\dfrac{5}{6} x + \dfrac{20}{3} -17

\sf \rightarrow y  = -\dfrac{5}{6} x -\dfrac{31}{3}

Please Help! Which statement best demonstrates why the following is a non-example of a polynomial?
Mama L [17]
I agree with you on this problem. It is A. If that is the final answer, the negative exponent must be flipped in order to be positive. According to the equation, it is not positive so it is not a simpflied polynomial.
