Answer:
1 solution
Step-by-step explanation:
y = 1/2x + 4
x + 2y = -8
Solve the second equation for y.
2y = -x - 8
y = -1/2x - 4
The two equations in slope-intercept form are:
y = 1/2x + 4
y = -1/2x - 4
The system consists of two lines with different slopes, so they intercept at a single point which is the solution.
Answer: 1 solution
Area= height x length
= (3x+5)²
= 9x²+30x+25
Perimeter= All sides added together
= 4 (3x+5)
= 12x + 20
Hope this helps!
Answer: The answer is option D. <em>Delphi Method Linear regression</em>
Step-by-step explanation: The <em>Delphi method </em>is a forecasting process framework used to estimate the likelihood and outcome of future events by group of <em>expert </em>with <em>relevant Knowledge</em>. The group of experts exchange views, and each independently gives estimates and assumptions to a facilitator who reviews the data and issues a summary report.
The steps involved in delphi method are;
- Choose facilitator
- Identifying experts
- Problem definition
- Round one questions
- Round two questions
- Round three questions
- Findings and conclusion
Note:
- You may choose tom have more than three rounds of questions to reach a more accurate consensus
- This technique is an iterative process, which tends to get broad range of opinions from the group of experts who will aid generation of forecast
