x² + 8 = -8
x² = -8 - 8
x² = 16
x = ±√-16
x = ±√16i
x = <span>±4i
</span>
18)
x² + 5 = -3
x² = -3 - 5
x² = -8
x = ±√-8
x = ±√8i
x = ±2√2i
19)
x² + 3 = 0
x² = -3
x = ±√-3
x = <span>±</span>√3i
hope this helps, God bless!
First, count the difference of the cost production and the selling cost
difference = 12 - 5.8
difference = 6.2
Second, transform the difference to percentage
percentage = difference/product cost × 100%
percentage = 6.2/5.8 × 100%
percentage = (620/5.8) %
percentage = 106.9%
The mark up cost is 106.9%
Answer:
y - 1 = 2(x - 2)
General Formulas and Concepts:
<u>Algebra I</u>
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, 1)
<u>Step 2: Write Equation</u>
- Substitute in variables: y - 1 = 2(x - 2)
