Answer:
C. Nonlinear
General Formulas and Concepts:
<u>Algebra I</u>
- Linear - Proportional relationship y = mx + b
- Nonlinear - Any graph that has a degree <em>x</em> higher than 1
Step-by-step explanation:
<u>Step 1: Define</u>
y = 6x³ - 13
<u>Step 2: Identify</u>
We see a cubic function. Quadratics, Cubics, Quartics, etc. are all nonlinear equations.
Answer:
C. There are about as many houses in Glendale that cost more than $650,000 than less than this amount.
Step-by-step explanation:
The mean means the average of something . We find the average of anything by the total weight divided by total number.
Average gives us a rough estimate of how much a thing cost or around 50 % of that thing what would be the cost be .
In the given question the best Choice is C as it explains that there are as many houses having more cost than $ 650,000 as many as having less cost than $ 650,000. This is true because an equal number of houses less than or more than $ 650,000 would sum up giving an average or mean of $ 650,000.
Answer: x=2
Step-by-step explanation:
To find the value of x, we have . To isolate x, we want to multiply both sides by 2 to get x alone.
x=2
Answer:
30 Chairs
Step-by-step explanation:
I will solve this problem using algebra and try to explain in detail.
We can form two equations with the information given to us.
Firstly, 5 times a length of chairs (I will call this unknown length of chairs x), plus 5 left over chairs, equals the total number of chairs (I will call the total number of chairs y).
5x + 5 = y
Secondly, 3 times a length of chairs (I will call this unknown length of chairs x), plus 15 left over chairs, equals the total number of chairs (I will call the total number of chairs y).
3x + 15 = y
Since both equations are equal to y, they are equal to each other
5x + 5 = 3x + 15
Take 5 away from both sides of the equals, and take away 3x from both sides of the equals
5x - 3x = 15 - 5
2x = 10
Divide both sides by 2
x = 5 chairs
Put this back into either the first equation or the second to solve for y
3 (5) + 15 = y
15 + 15 = y
y = 30 chairs
