Answer: <em>12n-20</em>

Step-by-step explanation:

<em>4(3n - 5)</em>

<em>Apply the distributive law: a(b-c) = ab-ac</em>

<em>a=4 b=3n c=5</em>

<em>Simplify 4 · 3n - 4 · 5: </em><em>12n-20</em>

(4 · 3n) - (4 · 5)

man this is taking forever to write

Multiply the numbers 4 · 3 =12

=12n - 4 · 5

Multiply the numbers: 4 · 5 = 20

⇒12n - 20

In 1 and 2, use the table below that shows information about squares.
frutty [35]

1. The table has a constant of proportionality of 4, therefore, the perimeter and side length of squares are proportional.

2. Equation for the proportion is, y = 4x.

Perimeter = 48 cm.

<h3>What is the Equation of a Proportional Relationship?</h3>

The equation that defines a proportional relationship is, y = kx, where k is the constant of proportionality between variables x and y.

1. For the table given:

y = perimeter

x = side length

k = constant of proportionality = 8/2 = 16/4 = 24/6 = 4.

Since k is the same all through, the equation can be modelled as y = 4x, which means the perimeter and side length of squares are proportional.

2. Using the equation, y = 4x,the perimeter (y) of a square when its side length is 12 (x) is:

y = 4(12)

y = 48 cm.

The perimeter (y) of the square is: 48 cm.

Please help me with these questions
Scrat [10]

3. Answer: y = 4

<u>Step-by-step explanation:</u>

Need to find the slope (m):

  \dfrac{y_2-y_1}{x_2-x_1}

  \dfrac{4 - 4}{-3-1}

= \dfrac{0}{-4}

= 0

Now input ONE of the points (1, 4) and the slope (m = 0) into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - 4 = 0(x - 1)

y - 4 = 0

y      = 4

********************************************************************

4. Answer: \bold{y = \dfrac{2}{3}x + 3}

<u>Step-by-step explanation:</u>

 y - y_1 = m(x - x_1)

 y - 1 = \dfrac{2}{3}(x - (-3))

 y - 1 = \dfrac{2}{3}(x + 3)

 y - 1 = \dfrac{2}{3}x + 2

 y = \dfrac{2}{3}x + 3
