Answer:

B. y = -3x + 2

Step-by-step explanation:

The equation for slope intercept form is y=mx+b

We need to find the slope and y-intercept.

<u>Let's find the slope first.</u>

Using the slope formula:

m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  } =\frac{-4-2}{2-0}=\frac{-6}{2}=-3

So, the slope of the points (0,2) and (2,-4) is -3.

-3 will replace m.

The Y-intercept, or b, is 2, since (0,2) is on the y-axis.

We end up with: y=-3x+2

<em>Option B is correct since it matches our equation. </em>

Help help help please homework is killing me right now

The domain of a function is the set of input or argument values for which the function is real and defined.

So, for the given function to be defined, we need to find the possible values for which the values of x makes the square root to be positive.

That is;

-9 -5x ≥ 0

Now, let's solve for x

Add 9 to both-side of the equation

-5x ≥ 9

Divide both-side by -5

x ≤ -9/5

Therefore, the domain of the function can be represented in interval notation as: ( - ∞ , -9/5]

A square region with perimeter 60 inches is made with square inch tiles. Bob removes one tile from the square and rearranges the
icang [17]

Answer:

  60 inches

Step-by-step explanation:

The perimeter will be minimized when the tiles are rearranged to form a rectangle with dimensions as close to each other as possible.

<h3>Rectangle dimensions</h3>

The square has a side length of ...

  P = 4s   ⇒   s = P/4 . . . . . P is perimeter, s is side length

  (60 in)/4 = 15 in . . . . length of the side of the square

The square has an area of ...

  A = s²

  A = (15 in)² = 225 in²

When 1 tile is removed, the resulting area, in square inches, is ...

  A = 225 -1 = 15² -1² = (15 -1)(15 +1) = 14×16

<h3>Perimeter</h3>

The perimeter of a rectangle is given by ...

  P = 2(L+W)

For this rectangle, the perimeter is ...

  P = 2(14 in + 16 in) = 2(30 in) = 60 in

The perimeter of the rectangle is 60 inches.
