Find the equality represented by the graph?

Talja [164]

Answer:

$-x+4y$

Step-by-step explanation:

Given: graph

To find:the inequality

Solution:

Equation of a line passing through points $(x_1,y_1),(x_2,y_2)$ is given by $y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Take $(x_1,y_1)=(0,3),(x_2,y_2)=(4,4)$

So,equation of line is evaluated as follows:

$y-3=\frac{4-3}{4-0}(x-0)\\ y-3=\frac{x}{4}\\ 4y-12=x\\-x+4y=12$

As per the graph,inequality is $-x+4y$

Here, use sign < and not $\leq$ as line in the graph is dotted that is points on the line are excluded.

The length of a rectangle is 3 m more than twice the width, and the area of the rectangle is 54 mº. Find the dimensions of the r

zhenek [66]

Answer:

The dimensions of rectangle are 12 m and 4.5 m

Step-by-step explanation:

Given that, The length of a rectangle is 3 m more than twice the width, and the area of the rectangle is 54 m²

Let's assume width of rectangle be x m and length be 3 + 2x m respectively. To find the dimensions of the rectangle we will use the formula of Perimeter of rectangle

$\\ { \underline{ \boxed{ \pmb{ \sf{ \purple{Area _{(rectangle)} = Length × width}}}}}} \\ \\$

Substituting values in above formula:

$\\ \dashrightarrow \sf \: \: (3 + 2x)(x) = 54 \\$

$\dashrightarrow \sf \: \: 3x + 2x^2 = 54 \\$

$\dashrightarrow \sf \: \: - 54 + 3x + 2x^2 = 0 \\$

$\dashrightarrow \sf \: \: 2x^2 + 3x - 54 = 0\\$

$\dashrightarrow \sf \: \: 2x^2 + 12x - 9x - 54 = 0\:$

$\dashrightarrow \sf \: \: 2x(x + 6) -9(x + 6) = 0\\$

$\dashrightarrow \sf \: \: (2x -9)(x+6) = 0 \\$

$\sf{x=}{\sf{\dfrac{9}{2}}}{\sf{\: or\: -6}}$

$\dashrightarrow \: \: { \underline{ \boxed{ \pmb{ \sf{\purple{ x = 4.5 }}}}}}$

Hence,

Length of rectangle = 3 + 2x = 3 + 2(4.5) = 12 m
Width of the rectangle = x = 4.5m

$\\ { \underline{ \pmb{ \frak{ \therefore Length \: and \: width \: of \: the \: rectangle \: is \:12 \: m \: and \: 4.5 \: m}}}} \\$
