Answer:
The answer to your question is: y = x/2 + 4
Step-by-step explanation:
Data
Point = (4, 6)
parallel to (6, -6) and (10, -4)
Formula
m = (y2 - y1) /(x2 - x1)
Process
First calculate the m
m = (-4 + 6) / (10 - 6)
m = 2 / 4
m = 1/2
Then we find the equation of the line
(y - y1) = m (x - x1)
y - 6 = 1/2 (x - 4) This is one equation
2(y - 6) = x -4
2y - 12 = x - 4
2y = x -4 + 12
2y = x + 8
y = x/2 + 4 This is another equation

<u>Explanation:</u>
We know
(x+y)ⁿ = ∑ ⁿCₐxⁿ⁻ᵃyᵃ
and ⁿCₐ = n! / ( a! ) . ( n-a )!
So,
(x+6)⁸ = ⁸C₀x⁸ + ⁸C₁(x)⁸⁻¹(6)¹ + ⁸C₂(x)⁸⁻²(6)² + ⁸C₃(x)⁸⁻³(6)³ + .......+ ⁸C₈(x)⁸⁻⁸(6)⁸
= ₓ⁸ + 8x⁷ₓ 6 + 28x⁶ₓ 36 + 56x⁵ₓ 216 + 70x⁴ₓ 1296 + 56x³ₓ 7776 + 28x²ₓ 46656 + 8x . 279936 + 1679616
= x⁸ + 48x⁷ + 1008x⁶ + 12096x⁵ + 90720x⁴ + 435456x³ + 1306368x² + 2239488x + 1679616
Thus, the expansion of ( x+6)⁸ using binomial theorm is
x⁸ + 48x⁷ + 1008x⁶ + 12096x⁵ + 90720x⁴ + 435456x³ + 1306368x² + 2239488x + 1679616
Answer:
$3.98
Step-by-step explanation:
To answer this, we can use simple division and multiplication.
Using the example of 2 pounds is equal to $7.96:
If 2 pounds = $7.96, then...
1 pound = ($7.96) divided by 2
1 pound = $3.98
Using the example of half a pound is equal to $1.99:
If 0.5 pounds = $1.99, then...
1 pound = ($1.99) x 2
1 pound = $3.98
