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>
y - 5 = 2(x + 2)
Answer:
7/12
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
Answer: -1/2
Step-by-step explanation:
-5/8 x 2/3
= -1/2
Product of polynomials can be done by distribution of multiplication over addition. The product of
is 
<h3>What is distributive property of multiplication over addition?</h3>
Suppose a, b and c are three numbers. Then we have:

(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

It is because when bases are same and there is multiplication, then powers add up, so we have: 
Also, we've

where -ve, +ve are sign of operands and result.
That's why 
Thus,
The product of
is
