Answer:

y - 5 = 2(x + 2)

General Formulas and Concepts:

Point-Slope Form: y - y₁ = m(x - x₁)  

x₁ - x coordinate

y₁ - y coordinate

m - slope

Step-by-step explanation:

<u>Step 1: Define</u>

Slope <em>m</em> = 2

Point (-2, 5)

<u>Step 2: Create equation</u>

Step-by-step explanation:

30+40+50=120

120 buttons in total

30+40=70

70 buttons that aren't white

70/120 is the probability

Simplify that to 7/12

Product of polynomials can be done by distribution of multiplication over addition. The product of  (2x - 3)(2x^2 + 7x  - 1) is 4x^3 + 8x^2 -23x + 3

<h3>What is distributive property of multiplication over addition?</h3>

Suppose a, b and c are three numbers. Then we have:

a(b + c) = a\times b + a\times c

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The product result of the given expression is

(2x - 3)(2x^2 + 7x  - 1)  = 2x(2x^2 + 7x  - 1) -3(2x^2 + 7x  - 1) \\(2x - 3)(2x^2 + 7x  - 1)  = 4x^{1+2} + 14x^2 -2x - 6x^2 - 21x + 3\\(2x - 3)(2x^2 + 7x  - 1)   = 4x^3 + (14 -6)x^2 + (-2 -21)x + 3\\(2x - 3)(2x^2 + 7x  - 1)   = 4x^3 + 8x^2 -23x + 3

It is because when bases are same and there is multiplication, then powers add up, so we have: a^b \times a^c = a^{b+c}

Also, we've

(-ve \times (+ve) = -ve\\(-ve) \times (-ve) = +ve\\(+ve) \times (+ve) = +ve\\(+ve) \times (-ve) = -ve

where -ve, +ve are sign of operands and result.

That's why 2 \times -1 = -2

Thus,

The product of   (2x - 3)(2x^2 + 7x  - 1)  is 4x^3 + 8x^2 -23x + 3
