Passes through (-1,4) and m=4
Ilya [14]
Point-slope formula;

y - y1 = m(x - x1)        given point(-1, 4) and slope(m) is 4.

y - 4 = 4(x - (-1)

y - 4 = 4x + 4

y = 4x + 4 + 4

y = 4x + 8               << the equation.

Linear equation: -1 2 (6x + 10) = 13 Step 1: –3x – 5 = 13 Step 2: –3x = 18 Step 3: x = –6 Which sequence describes the inverse o
djverab [1.8K]

Answer:

  (A)  the addition property of equality and then the division property of equality

Step-by-step explanation:

To get from Step 1 to Step 2, we have added 5 to both sides of the equation:

  -3x -5 +5 = 13 +5

  -3x = 18

To get from Step 2 to Step 3, we have divided both sides of the equation by -3:

  -3x/-3 = 18/-3

  x = -6

These operations can be described as ...

  the addition property of equality and then the division property of equality

__

However, since addition and subtraction are the same thing, but with opposite numbers, and since multiplication and division are the same thing, but with reciprocal numbers, <em>any of the answer choices is arguably correct</em>.

  (add 5, divide by -3) = (add 5, multiply by -1/3) =

  (subtract -5, divide by -3) = (subtract -5, multiply by -1/3)

Claire made 1⁄2 pound of trail mix. If she puts 1⁄4 pound of trail mix into each bag, how many bags are filled?
aleksklad [387]
Claire would have filled two bags.
1/2 (or .5) ÷ 1/4 (or .25) = 2

Since both units are in pounds, you don't need to convert anything.
