ziro4ka [17]

Width : Length

2 : 3

Perimeter = 2* width + 2*length

Ratio becomes:

Width : Length

4 : 6

Total units = 4 + 6 = 10

Perimeter = 40

Answer: Width is 8 ft and Length is 12 ft.

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

Answer:

<em>The value of y when x has a value of 9 is 18</em>

Step-by-step explanation:

<u>Functions</u>

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

Graph the line for y + 1 equals -3/5 parentheses x subtract 4 parentheses

Stolb23 [73]

Answer:

The graph is shown below.

Step-by-step explanation:

Given:

Equation of a line is $y+1=-\frac{3}{5}(x-4)$

The equation of a line with a point $(x_{1},y_{1})$ and slope $m$ is given as:

$y-y_{1}=m(x-x_{1})$

On comparing the given equation with the standard form, we get

$x_{1}=4,y_{1}=-1,m=-\frac{3}{5}$

Now, we first plot the point $(4,-1)$ .

Slope is $-\frac{3}{5}$ . This means that we have to move 3 units down and 5 units right to get the slope as negative. We mark the second point there.

Now, we plot a line joining both the points. Thus, the graph is drawn.
