4x-2y=12 -4x-9=54 How can you order a ladder?

Equations:

4x - 2y = 12
-4x - 9y = 54

Multiple them in both sides

4x - 2y - 4x - 9y = 12 + 54
-2y - 9y = 66
-11y = 66
y= -6

If y= -6 then put y in first or second equation.

I put it in first equation

4x - 2.(-6) = 12
4x + 12 = 12
x= 0

Therefore

(x,y) = (0, -6)

How do you do this? please help me
Anastaziya [24]

Answer:

f = 10, g = 4.8 cm

Step-by-step explanation:

Area of ABCE = 60 cm²

Area of ABCD = 48 cm²

So,

Area of ADE = 60-48

=> 12 cm²

Area of ADE = \frac{1}{2} (Base)(Height)

<u><em>Where Area = 12 cm², Base = 4 cm</em></u>

12 = \frac{1}{2}(4)(Height)

Height = 12-2

Height = 10 cm

Where Height is AD

So, AD = 10 cm

Also, <u><em>AD is parallel and equal to BC</em></u>(f)<u><em></em></u>

So,

f = 10 cm

<u><em>Now, Finding g</em></u>

Area of ABCD = Base * Height

<u><em>Where Area = 48 cm², Base = 10 cm</em></u>

48 = 10 * Height

Height = 48/10

Height = 4.8 cm

Whereas, Height is g

So, g = 4.8 cm

Write the equation of a circle whose center is at (-1,5) and radius is 8
labwork [276]

Answer:

X²+y²+2x-10y+18=0 is the equation of circle

Step-by-step explanation:

Eqn of circle is: (x-h) ²+(y-k)²=r²

At (h, k) =(-1,5) and r=8 where h, k are center and r is radius.

Eqn is :(x+1)²+(y-5)²=8²

Or, x²+2x+1+y²-10y+25=8

Or, x²+y²+2x-10y+18=0 is the equation of circle
