Step-by-step explanation:

i can't figure it out

Answers

Answer:

see explanation

Step-by-step explanation:

Given

x - 6y = 18

To find the x- intercept let y = 0 in the equation and solve for x, that is

x - 0 = 18

x = 18 ← x- intercept ⇒ (18, 0 )

To find the y- intercept let x = 0 in the equation and solve for y, that is

0 - 6y = 18

- 6y = 18 ( divide both sides by - 3 )

y = - 3 ← y- intercept ⇒ (0, - 3 )

Step-by-step explanation:

If you are solving for a ∆, a ∆ has a degree of 180º. This thus when added up gets you.

81º + 39º = 120º

180º - 120º = 60º

Therefore in conclusion, X would be 60º.

Find the perimeter and area of the figure if each unit on the graph measures 1 centimeter. Round answers to the nearest tenth, if necessary. A(0,9) B(4,9) C(0, 1)​

Answers

Answer:

Area = 16 cm²

Perimeter = 20.9 cm

Step-by-step explanation:

To find the perimeter and area of the given triangle length of all sides of the given triangle will be required.

Use the formula to determine the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],

d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance between A(0,9) and B(4, 9),

AB = [tex]\sqrt{(4-0)^2+(9-9)^2}[/tex] = 4 cm

Distance between A(0,9) and C(0, 1),

AC = [tex]\sqrt{(0-0)^2+(9-1)^2}[/tex]

AC = 8 cm

Distance between B(4, 9) and C(0, 1),

BC = [tex]\sqrt{(4-0)^2+(9-1)^2}[/tex]

BC = [tex]\sqrt{16+64}[/tex]

     = [tex]\sqrt{80}[/tex]

     = [tex]4\sqrt{5}[/tex]

     = 8.9 cm

Area of ΔABC = [tex]\frac{1}{2}(\text{AC})(\text{AB})[/tex]

                        = [tex]\frac{1}{2}(8)(4)[/tex]

                        = 16 cm²

Perimeter of the triangle = AB + AC + BC

                                         = 4 + 8 + 8.9

                                         = 20.9 cm

Answers

Step-by-step explanation:

Hey there!

Your answer is Option A.

Check all:

A. y = 6x-2

Comparing the equation with y = mx+b, we get;

m= 6

and b= -2

B. y= 6x+2

Comparing the equation with y= mx+b, we get;

m = 6

b= 2

C. y = 2x+6

Comparing the equation with y= mx+b, we get;

m= 2

b = 6

D. y= -2x-6

Comparing the equation with y= mx+b, we get;

m= -2

b= -6

Therefore, Option A is correct answer.
