Answer:

$\frac{3}{4}$ = $\frac{9}{12}$

Step-by-step explanation:

The values are in proportion if the right side is a multiple of the left side

Consider

$\frac{3}{4}$ × $\frac{3}{3}$

= $\frac{3(3)}{4(3)}$

= $\frac{9}{12}$

Thus $\frac{3}{4}$ and $\frac{9}{12}$ are in proportion

This does not happen for any of the other three.

A landscape architect is designing a rectangular garden in a local park. The garden will be 35 feet long and 15 feet wide. The a

N76 [4]

Given length of the garden = 35 feet

Given width of the garden = 15 feet

Let's assume the walkway has a width of x feet.

The figure of the garden with walkway is attached below.

Length of walkway= $35+x+x = 35+2x$

Width of walkway = $15+x+x = 15+2x$

Area of walkway = length of walkway * width of walkway

Area = $(35+2x)(15+2x)$

Area = $(35*15) + (35*2x) + (15*2x) + (2x*2x)$

Area = $4x^2+100x+525$ .... Answer

Choose the correct answer for each of the following questions Find the y-intercept for following equation F(X)=-(X+1)^21- -12- -

devlian [24]

Solution

Find the y-intercept for following equation:

$f(x)=-(x+1)^2$

Using the slope equation formular:

$\begin{gathered} y=mx+c \\ f(x)=-(x+1)^2 \\ f(x)=-x^2-2x-1 \end{gathered}$

The value of y when x = 0

$\begin{gathered} f(0)=-0^2-2(0)-1 \\ y=-1 \end{gathered}$

Hence the answer is - 1
