Answer:

m= - 2, b = 4

Step-by-step explanation:

structure of a linear equation

y = mx + c

m = gradient / slope

c = intercept

<em>convert</em><em> </em><em>the </em><em>given </em><em>equation</em><em> </em><em>according </em><em>to</em><em> </em><em>this</em><em> </em><em>structure</em><em> </em><em>of</em><em> </em><em>linear </em><em>equations</em><em> </em>

4x+2y = 8

2y = -4x + 8

y = -2x +4

<em>according</em><em> </em><em>to</em><em> </em><em>this </em><em>intercept</em><em> </em><em>is </em><em>4</em><em> </em><em>and </em><em>slope </em><em>is </em><em>-</em><em>2</em>

the denominator of a fraction is 3 less than the numerator. If 5 is added to the numerator and denominator, the result is 5/6. F
Vitek1552 [10]
X=numerator
y=denominator
the sum of numerator and denominator=x+y
we suggest this system of equations:

y=x-3
(x+5) / (y+5)=5/6

we solve this system of equation by substitution method.
(x+5) / (x-3+5)=5/6
(x+5) / (x+2)=5/6
6(x+5)=5(x+2)
6x+30=5x+10
6x-5x=10-30
x=-20

y=x-3=-20-3=-23

Teh sum of the numerator an denominator=-20+(-23)=-43

Answer:    -43

Multiply the top equation by 6 and the bottom equation by 7. You will cancel x first by doing this and solve for y. You should get y=-1.
Substitute in y for either original equation.
You should get x=1.
Solution is (1,-1).

A small square of side 2x is cut from the corner of a rectangle with a width of 10 centimeters and length of 20 centimeters. Wri
love history [14]
Find the area of the rectangle. You can find the area of a rectangle with the following formula:

A = wl

w = width, and l = length.

Plug in your width and length:

20 * 10 = 200

The area of the rectangle is 200 square centimeters.

The area of a square is also given by width * length. Multiply the sides together:

2x * 2x = 4x^{2}

The area of a square is 4x^2.

Because you're cutting away the square from the rectangle, you will subtract the area of the square from the area of the rectangle. The following equation will be your answer:

200 - 4x^{2} cm^{2}
