Answer:

Step-by-step explanation:

The zeros are the points on the x- axis where the graph crosses

In this case there are 2 points where the graph crosses the x- axis

These are the zeros , that is 2 zeros

The perimeter of a rectangle is 72 cm. The length is 3 more than twice the width What

solmaris [256]

<h3>Solution</h3>

Given :-

Perimeter of rectangle = 72 cm
The length is 3 more than twice the width.

Find :-

Dimensions of rectangle

<h3 /><h3>Explantion</h3>

Using Formula

$\boxed{\underline{\tt{\red{\:(perimeter_{rectang}\:=\:2\times (Length+Width)}}}}$

Let,

Length of Rectangle = x cm
Breadth of Rectangle = y cm

According to question,

==> perimeter of Rectangle = 72

==> 2(x+y) = 72

==> x + y = 72/2

==> x + y = 36_________________(1)

Again,

==> x = 2y + 3

==> x - 2y = 3__________________(2)

Subtract equ(1) & equ(2)

==> y + 2y = 36 - 3

==> 3y = 33

==> y = 33/3

==> y = 11

keep in equ(1)

==> x - 2×11 = 3

==> x = 3 + 22

==> x = 25

<h3>Hence</h3>

Length of Rectangle = 25 cm
Width of Rectangle = 11 cm

Answer:

Refer the attached figure.

Step-by-step explanation:

Given : Function $f(x)=2x-3$

To find : Graph the given function?

Solution :

We have given the function $f(x)=2x-3$ is a linear function which passes through origin the points

x f(x)

0 -3

1.5 0

1 -1

Joining these points will create a graph of a line with slope 2.
