Y + 3 = x - 1
    - 3    - 3
      y = x - 4

The slope-intercept form of the equation of the line is y = x - 4.

Katie cut out a rectangular piece of wrapping paper that was 2 times as long and 3 times as wide as the box that she was wrappin
kotegsom [21]
2*5=10 (the measure of one long side is 10)
3*4=12 (the measure of one wide side is 12)


A box has four sides to the perimeter of the flat wrapping paper must consist of four edges.  Because we know that one edge is 10 inches long and another side is 12 inches wide we assume that the corresponding sides are equal.  


So now we know that we have two sides that are 10 inches and 2 sides that are 12 inches.


10+10+12+12= 44 inches

9 to the power 18 = 27 to the power x work out the value of x
Strike441 [17]

Answer:

Step-by-step explanation:

27^x = 9÷(3^x)

So (3^3)^x = (3^2)÷(3^x)

So 3^3x = 3^(2-x)

Comparing powers on both sides,

3x = 2 - x

So, 4x = 2

So, x = 1/2

Given ( 27 ) ^ x = 9 / 3 ^x

⇒ ( 3 × 3 × 3 )^x = ( 3 × 3 ) / 3^x

⇒ ( 3 ³ )^x = 3² / 3^x

⇒  3 ^ 3x × 3^x = 3²            [ since  ( a ^m)^n = a ^mn ]

⇒ 3^ (3x +x) = 3²                [ since a^m × a^n = a ^m+n ]

⇒ 3^4x = 3²

⇒4x = 2                      [ since  If a ^m = a ^n then m = n ]

⇒ x = 2 / 4

 ∴ x = 1 / 2

I hope this helps you.

In ABC, the sum of the measures of Angle A and angle B is 47°. What is the measure of Angle C ?
puteri [66]

Answer:

∠ C = 133°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , that is

∠ A + ∠ B + ∠ C = 180° ( substitute A + B = 47° )

47° + ∠ C = 180° ( subtract 47° from both sides )

∠ C = 133°
