What are the choices ? ? ?

There re an infinite number of points on the graph.
Here is a small sampling:

(2, 1)
(6, 3)
(12, 6)
(16, 8)
(20,10)
(30, 15)
(40, 20)
(50, 25)
(76, 38)
(82, 41)
(102, 51)
(202, 101)
(30000, 15000) .

Also, take any one of those points, make both numbers negative,
and you'll have another point on the graph.

Use the graph to write a linear function that relates y to x

Answers

The equation of a line can be predicted easily if two points are given. Thus, the equation of the required line is $\bold{y=4}$ .

We need to determine the equation of the line with the help of the given graph.

Now, take two points from the graph. The points are ( 1, 4 ) and ( 2, 4 ).

The if a line passed through the two points say $(x_1,y_1)\;\rm{and}\;(x_2,y_2)$ , then the equation of the line can be formulated as:

$(y-y_1)=(y_2-y_1)/(x_2-x_1)(x-x_1)$

Therefore, apply the formula and solve it further.

$\begin{aligned} (y-4)&=(4-4)/(3-2)(x-1)\ny-4&=0\ny&=4 \end{aligned}$

Thus, the equation of the line is $\bold{y=4}$

A rectangle has a perimeter of 52 cm and an area of 144 square cm. Find its length and width if they are in whole numbers.

Answers

The length of the rectangle will be 18 cm.

The width of the rectangle will be 28 cm.

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The perimeter of rectangle = 52 cm

An Area of a rectangle = 144 cm²

Let the length of the rectangle = l

The width of the rectangle = b

So, We get;

⇒ 2 (l + b) = 52

⇒ l + b = 26 ..(i)

And, l x b = 144 ..(ii)

Since, (l - b)² = (l + b)² - 4lb

= (26)² - 4 × 144

= 676 - 576

= 100

⇒ l - b = √100

⇒ l - b = 10 ..(iii)

Solve equation (i) and (iii), we get;

⇒ l = 18 cm

⇒ b = 28 cm

Thus, The length of the rectangle will be 18 cm.

The width of the rectangle will be 28 cm.
