I will mark you brainiest if you can answer this
Korvikt [17]

Answer:

12^4 or 20736

Step by Step Instructions:

really all you have to do is subtract the exponents. 12^7-12^3=12^4, if you want to expand the numbers you can do it that way too. 12^7=35831808, 12^3=1728, 35831808/1728=20736 (which is the same as 12^4)

Seven and two hundred sixty-seven ten thousandths as a decimal
coldgirl [10]

7.0267

Step-by-step explanation:

The clue here is that the decimal point follows after the "and"

For example,

One and one thousandth = 1 + 1/1000 = 1.001

One and two hundred sixty-three thousandths = 1+ 263/1000 = 1.263

Hence;

seven and two hundred sixty-seven ten thousandths= 7+ 267/10000= 7.0267

Line CD passes through points C(3, –5) and D(6, 0). What is the equation of line CD in standard form?
Elden [556K]
Slope =   (y₂- y₁) / (x₂- x₁)

Points  C( 3, -5) and D (6, 0)  compare to (x₁, y₁) and  (x₂, y₂)

Slope = (0 - -5) / (6- 3)  =   (0+5) / (3) =  5/3

Slope = 5/3

Equation of line given a slope and point,   y - y₁ = m(x - x₁)

m = 5/3,    let point C( 3, -5) = (x₁, y₁)

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

   3(y + 5) = 5(x - 3)
  
    3y + 15 = 5x - 15

     3y =  5x - 15 - 15

     3y = 5x - 30

Hence the equation of the line is 3y = 5x - 30
