What is the y and slope intercepts of this table?
Veronika [31]

Answer:

The answer to your question is y-intercept = 22, slope = -6

Step-by-step explanation:

- To find the answer you need to find the equation of the line.

Process

1.- Find the slope

slope = m = (y2 - y1) / (x2 - x1)

x1 = 2       y1 = 10      x2 = 3    y2 = 4

-Substitution

            m = (4 - 10) / (3 - 2)

-Simplifying

            m = -6/1

-Result

            m = -6

2.- Find the equation of the line

            y - y1 = m(x - x1)

-Substitution

            y - 10 = -6(x - 2)

-Simplifying

            y - 10 = -6x + 12

            y = -6x + 12 + 10

-Result

            y = -6x + 22

3.- Conclusion

y-intercept = 22

slope = -6

This rectangle and right triangle have the same perimeter.
GuDViN [60]

Answer:

0.18 cm²

Step-by-step explanation:

Given that a rectangle and a triangle have same perimeter . The sides of them are ,

\begin{cases} Square = 4cm , 4cm , 3cm \ and \ 3cm .\\ Triangle = 4cm , 5.8cm \ and \ 4.2cm \end{cases}

We know that area of rectangle is product of length and breadth.

\implies Area = length \times breadth \\\\\implies Area = 4cm \times 3cm\\\\\implies \red{ Area = 12cm^2}

Also we know that the area of triange is half the product of base and height . So that ,

\implies Area = \dfrac{1}{2}\times 5.8cm \times 4.2 cm \\\\\implies \red{ Area = 12.18 cm^2 }

Therefore the difference between them is ,

\implies D = A_1 - A_1 \\\\\implies D = 12.18cm^2-12cm^2 \\\\\implies \red{D = 0.18 cm^2}
