Solve the system of equations below by graphing each line on the coordinate plane provided. Then place a point where the solution of the system occurs. 3x + 2y = 8 x + 2y = 4​

Answer:

[tex](5y + 1)^{2} - (2(y - 1))^{2} [/tex]

Step-by-step explanation:

1) Rewrite it in the form a² - b², where a = 5y + 1 and b = 2(y - 1 ).

[tex](5y + 1) ^{2} - (2(y - 1)) ^{2} [/tex]

2) Use multiplication Distributive Property: (xy)^a = x^a y^a.

[tex](5y + 1)^{2} - {2}^{2} (y - 1 {)}^{2} [/tex]

3) Simplify 2² to 4.

[tex](5y + 1 {)}^{2} - 4(y - 1 {)}^{2} [/tex]

4) Rewrite it in the form a² - b², where a = 5y + 1 and b = 2(y-1).

[tex](5y + 1 {)}^{2} - (2(y - 1))^{2} [/tex]

Therefor, the answer is ( 5y + 1 )² - (2( y - 1 ))².

Answer:

m∠2=9

Step-by-step explanation:

Hello There!

The problem states that the angles are complementary angles

Complementary angles are angles that have measures that add up to equal 90

So given one of the angles we can find the missing angle by subtracting the known angle from 90

90 - 81 = 9

so we can conclude that the measure of angle 2 is 9

Answer:

62 grados x

Step-by-step explanation:

Answer:

because the first side equal for the second side this means that this triangle is isosceles

so 62+62=124

sum of the angles of any triangle =180

180°-124=56degree

Answer:

Answer:

54 feet

Step-by-step explanation:

Perimeter of a rectangle = 2 × (length + breadth)

The perimeter of Edwin's garden is 36 feet :

36 = 2 x (length + breadth)

divide both sides by 2 to determine the sum of the length and breadth of Edwin's garden

36/2 = (length + breadth)

18 = (length + breadth)

Tony's garden is 4 feet longer and 5 feet wider than Edwin's garden

The dimensions of Tony's garden is :

(4 + l) + (5 + w) = 9 + l + w

Where :

l = length

w = width

The sum of the length and breadth of Tony's garden would be 9 feet more than that of Edwin

Sum of Edwin's garden = 9 + 18 = 27

Perimeter of Edwin's garden = 27 feet x 2 = 54 feet

Answer:

167.55

Step-by-step explanation:

Formula - V = [tex]\pi r^2\frac{h}{3}[/tex]

V = [tex]\pi (4)^2\frac{10}{3}[/tex]

V = 167.55

Answer:

So, basically AB goes through (bisects) CAD, which CAD is the kite-like shape you see. So line AB goes through line CAD. Now what they what you to do is prove if lines AB and lines AC are equal.

just chose the last one 75% are stars

Answer:

I think it's 145.225 sq in.

Step-by-step explanation:

2.5 x 2 x 3.14 = 15.7

15.7 x 9.25 = 145.225

Answer:

its the second one

Step-by-step explanation:

2.5 x 2 x 3.14 = 15.7 because 3.14 is pi

and then do

15.7 x 9.25 = 145.225 so there you go

Step-by-step explanation:

The distances they jumped were

x,y,z

y=x+2

z=x+2+2=x+4

x+y+z=12.69

x+x+2+x+4=12.69

3x+6=12.69

3x=6.69

x=2.23

So Jack jumped 2.23m, Alex jumped 4.23m, and Amir jumped 6.23m.

Answer:

La ecuación de la recta es [tex]y = -6\cdot x +23[/tex].

Step-by-step explanation:

Para construir la ecuación de la recta podemos utilizar un punto contenido en la recta y su pendiente. En primer punto, hallamos el punto con la resolución del siguiente sistema de ecuaciones lineales:

[tex]x+4\cdot y = 0[/tex] (1)

[tex]x-3\cdot y = 7[/tex] (2)

La solución del sistema de ecuaciones es [tex](x,y) = (4,-1)[/tex].

Por Geometría Analítica, sabemos que la Ecuación de la Recta en su forma explícita es:

[tex]y = m\cdot x + b[/tex] (3)

Donde:

[tex]x[/tex] - Variable independiente.

[tex]y[/tex] - Variable dependiente.

[tex]m[/tex] - Pendiente.

[tex]b[/tex] - Intercepto.

Si sabemos que [tex](x,y) = (4,-1)[/tex] y [tex]m = -6[/tex], entonces el intercepto de la recta es:

[tex]b = y-m\cdot x[/tex]

[tex]b = 23[/tex]

Ahora, la ecuación de la recta es [tex]y = -6\cdot x +23[/tex].

Answer:

Step-by-step explanation:

6 5/10 - 1 7/10

= (6 - 1) + (5/10 - 7/10)

= 5 + 5 - 7/10

= 5 + -2/10

= 5 + -2 ÷ 2/10 ÷ 2

= 5 + -1/5

= 4 4/5

Can i hav brainliest plz it would help alot :D

Answer:

The circumference of a circle is equal to π , which is a number ≈3.14 , multiplied by the diameter of the circle. Therefore ... We also know that the diameter has twice the length of the radius. In equation form: 2r=d. 2r=16. r=8. Note that since 2r=d , the equation C=2πr holds and can be used in place of C=πd .

Answer:

21:  37

They are the opposite side exterior angles

22: 40

23:  126

They are the opposite side exterior angles

24: 1

25: 12

90 - 48 = 42

42 = 3x + 6

36 = 3x

12 = x

26:   41

180 - 139 = x

41 = x

27:   140

180 - 40 = 140

28: 68

90 - 22 = 68

29: False

Complementary angles add up to 90 degrees
