You just work out the problems on the top and bottom separately, then put the answers over each other and divide. The answer should be 10.

What is the answerrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

Alecsey [184]

Answer:

$1559.40

Step-by-step explanation:

1. Find the perimeter of the garden

$14\frac{2}{3} + 14\frac{2}{3} + 10\frac{1}{3} + 10\frac{1}{3} = 50 yd$

2. Convert to feet

1 yd = 3ft

50 x 3 = 150

50 yd = 150 ft

3. Divide by 2.5 to find out how many sections are needed

150/2.5 = 60 sections

4. Multiply by 25.99

60 x 25.99 = 1559.4

It will cost $1559.40

Let's analyze each part of the function:

FROM x = 0 TO x = 5:

We can find the equation of this line by using The Slope-Intercept Form of the Equation of a Line, that states:

$The \ graph \ of \ the \ equation: \\ \\ y=mx+b \\ \\ is \ a \ line \ whose \ slope \ is \ m \ and \ whose \ y-intercept \ is \ (0, b)$

So the y-intercept here is $(0,4)$ and $m=\frac{4}{5}$ , therefore:

$\boxed{y=\frac{4}{5}x+4}$

FROM x = 0 TO x = 5:

From the previous line, we know that at $x=5$ the output is:

$y=\frac{4}{5}x+4 \\ \\ y=\frac{4}{5}(5)+4 \\ \\ y=4+4=8$

So the point $P_{1}(5,8)$ lies on both lines.

For this new line, the slope is $m=-\frac{3}{5}$

So, with the Point-Slope Form of the Equation of a Line we can find the equation of this other line:

$The \ equation \ of \ the \ line \ with \ slope \ m \\ passing \ through \ the \ point \ (x_{1},y_{1}) \ is:\\ \\ y-y_{1}=m(x-x_{1})$

So:

$y-8=-\frac{3}{5}(x-5) \\ \\ y=8-\frac{3}{5}x+3 \\ \\ \boxed{y=-\frac{3}{5}x+11}$

The graph is shown below.

The graph of the linear function $f(x)=ax+b$ is a line with slope $m=a$ and $y-intercept$ at $(0,b)$ . From the items, we can assure that the following equations are linear functions:

$\bullet 3y=2x-1.5 \ because \ y=\frac{2}{3}x-\frac{1}{2} \\ \\ \\ \bullet y=1 \ because \ y=m(0)+1 \\ \\ \\ \bullet 5(x+y)=-25 \ because \ 5x+5y=-25 \ \therefore 5y=-5x-25 \therefore y=-x-5$

In conclusion, the other functions are nonlinear and they are:

$\bullet \ y=x^2+3 \\ \\ \bullet \ y=x^3 \\ \\ \bullet \ y=12-x^2$
