Consider the following expression and determine which statements are true.

Serhud [2]

Given:

$$\frac{7}{r}+2^{3}+\frac{s}{3}+11$

To find:

Which statement are true?

Solution:

Option A: The entire expression is a sum.

It is true because it performed addition operation.

Option B: The coefficient of s is 3.

$$\frac{7}{r}+2^{3}+\frac{s}{3}+11=\frac{7}{r}+2^{3}+\frac{1}{3}s+11$

It is not true because the coefficient of s is $\frac{1}{3}$ .

Option C: The term $\frac{7}{r}$ is a quotient.

If we divide 7 by r, we obtain a quotient.

So it is true.

Option D: The term $2^3$ has a variable.

It is not true because it does not contain any variable.

Therefore the entire expression is a sum and the term $\frac{7}{r}$ is a quotient are true statement.

The variables x and y have a quadratic relationship. Tripling the value of x causes the value of y to increase by a factor of ni

Lady bird [3.3K]

Answer:

The value of y when x has a value of 9 is 18

Step-by-step explanation:

Functions

The variables x and y are said to have a quadratic relationship. That information is not enough to set up a general equation for both variables.

Furthermore, we know that tripling the value of x causes the value of y to be multiplied by 9. That leads us to establish a proportional equation between them, as follows:

$y=kx^2$

Where k is an unknown constant.

Let's use the given point (3,2) to find the value of k:

$2=k(3)^2$

$2=9k$

Solving for k:

$\displaystyle k=\frac{2}{9}$

The equation is now:

$\displaystyle y=\frac{2}{9}x^2$

Now find y when x=9:

$\displaystyle y=\frac{2}{9}(9)^2$

$\displaystyle y=\frac{2}{9}\cdot 81=18$

The value of y when x has a value of 9 is 18
