Answer:

y=3x-6

Step-by-step explanation:

use 2 of the points for y=a×x+b

we use (2,0) and (3,3) as an example

we get

0=2a+b & 3=3a+b

3-0=3a+b-(2a+b)

3=a

b=-6

Ira Lisetskai [31]

Answer:

1 m by 189 m

Step-by-step explanation:

The perimeter is 2(70+120)=380.

The area is (70)(120)=8400.

If we let the park have a width of 1 meter and a length of 189 meters, then the area will be 189 square meters, which is smaller than 8400 square meters, as required.

Which points are on the graph of g(x) = (1/5)x?

AlexFokin [52]

Given:

The function is

$g(x)=(\dfrac{1}{5})^x$

To find:

The correct ordered pairs.

Solution:

We have,

$g(x)=(\dfrac{1}{5})^x$

For x=3,

$g(3)=(\dfrac{1}{5})^3$

$g(3)=\dfrac{1}{125}$

So, the ordered pair is $(3,\dfrac{1}{125})$ .

For x=-2,

$g(-2)=(\dfrac{1}{5})^{-2}$

$g(-2)=(5)^2$ $[\because (\dfrac{a}{b})^{-n}=(\dfrac{b}{a})^n]$

$g(-2)=25$

So, the ordered pair is $(-2,25)$ .

For x=1,

$g(1)=(\dfrac{1}{5})^1$

$g(1)=\dfrac{1}{5}$

So, the ordered pair is $(1,\dfrac{1}{5})$ .

For x=-1,

$g(-1)=(\dfrac{1}{5})^{-1}$

$g(-1)=(5)^1$ $[\because (\dfrac{a}{b})^{-n}=(\dfrac{b}{a})^n]$

$g(-1)=5$

So, the ordered pair is (-1,5). This is the correct answer.

Therefore, the correct option is D.
