Solve negative 5 times y plus seven thirds times y equals negative 5 minus eight thirds times y minus 4 for y.

Answer:

None of the Above?

Step-by-step explanation:

1.) If we put this into words, we would get -5y+7/3y=-5-8/3y-4

2.) By moving all y terms to one side, we get -5y + 7/3y + 8/3y = -5 - 4

3.) By simplifying, you would get -4 2/3y = -9.
4.) If you divide both sides by -4 2/3, you would get that y = -9 * - 3/14 = 27/14

<u>Function Modeling</u>

The behavior of some parameters that depend on a set of variables can be modeled in several ways, like linear, quadratic, exponential, logarithmic, among many others.

The selection of the model is often a complex decision that involves statistics and data analysis.

The question provides us with four points where the volume of popcorn bags and the price in dollars. The easiest function that can be used is the line.

The equation of a line of the volume V and the price p can be found with the expression

$\displaystyle p-p_1=\frac{p_2-p_1}{V_2-V_1}(V-V_1)$

We'll use the first two values (6,10) (8,20)

$\displaystyle p-6=\frac{8-6}{20-10}(V-10)$

Simplifying and rearranging, we get the model

$\displaystyle p(V)=\frac{1}{5}V+4$

To test the accuracy of the model, we compute the values of p for V=35 and for V=48

$\displaystyle p(35)=\frac{1}{5}(35)+4=11$

$\displaystyle p(48)=\frac{1}{5}(48)+4=13.6$

Since the computed values are equal to those of the table, the model is accurate. We can now predict the price for V=60

$\displaystyle p(60)=\frac{1}{5}(60)+4=16$

The price for a 60-ounce bag of popcorn would be $16

Simplify 6/6^1/4 rational exponents

White raven [17]

Answer:

we conclude that:

$\frac{6}{6^{\frac{1}{4}}}=6^{\frac{3}{4}}$

Step-by-step explanation:

Given

The expression is

$\frac{6}{6^{\frac{1}{4}}}$

To determine

Simplify the expression

Simplifying the expression

$\frac{6}{6^{\frac{1}{4}}}$

Apply the exponent rule: $\frac{x^a}{x^b}=x^{a-b}$

$\frac{6}{6^{\frac{1}{4}}}=6^{1-\frac{1}{4}}$

Subtract the numbers: $1-\frac{1}{4}=\frac{3}{4}$

$=6^{\frac{3}{4}}$

Therefore, we conclude that:

$\frac{6}{6^{\frac{1}{4}}}=6^{\frac{3}{4}}$
