PLZZ HELP ME 20 POINTS AND BRAINLIEST!
omeli [17]

Answer:

The price of price of the stock after it has been owned for 12 weeks is $92.55

Step-by-step explanation:

Given: The price of a particular stock is represented by the linear equation

y = -0.91x + 103.47

where x represents the number of weeks the stock has been owned and y represents the price of the stock, in dollars.

We have to find the price of price of the stock after it has been owned for 12 weeks.

Since , x represents the number of weeks the stock has been owned.

Thus, by substitute, x = 12

We get the value of y , the price of stocks.

Thus, y(x) =  -0.91x + 103.47

⇒ y(12) =  -0.91(12) + 103.47

⇒ y(12) =  -10.92 + 103.47

Solving , we get,

⇒ y(12) = 92.55

Thus, the price of price of the stock after it has been owned for 12 weeks is $92.55.

The ratio of students to adults on a field trip is 8 to 1. Which table correctly shows this ratio for each grade?
elena-14-01-66 [18.8K]

Answer:

The table C correctly shows the ratio 8:1  for each grade

Step-by-step explanation:

Let

x ----> the number of students

y ----> the number of adults

we know that

\frac{x}{y}=\frac{8}{1}

<u><em>Verify each table</em></u>

Table A

grade 6

\frac{96}{88}=\frac{8}{1}

Multiply in cross

96(1)=8(88) ----> is not true

Table B

grade 6

\frac{96}{104}=\frac{8}{1}

Multiply in cross

96(1)=8(104) ----> is not true

Table C

<u><em>grade 6</em></u>

\frac{96}{12}=\frac{8}{1}

Multiply in cross

96(1)=8(12)

96=96 ----> is true

<u><em>grade 7</em></u>

\frac{120}{15}=\frac{8}{1}

Multiply in cross

120(1)=8(15)

120=120 ----> is true

<u><em>grade 8</em></u>

\frac{136}{17}=\frac{8}{1}

Multiply in cross

136(1)=8(17)

136=136 ----> is true

therefore

The table C correctly shows the ratio 8:1  for each grade

Table D

<u><em>grade 6</em></u>

\frac{96}{11}=\frac{8}{1}

Multiply in cross

96(1)=8(11)----> is not true
