First line....solid line...means there is an equal sign in the problem....it has a y int of (0,2)....it has a slope of -1/3....and it is shaded below the line...the inequality for this line is : y < = - 1/3x + 2 <== this is one of them
2nd line...dashed line...means there is no equal sign....it has a y int of (0,3)...it has a slope of 2/3...and it is shaded above the line...so the inequality for this line is : y > 2/3x + 3 <== this is ur other inequality
Answer:
- Decay rate, r = 0.014
- Initial Amount =120,000
- P(10)=104,220
Step-by-step explanation:
The exponential function for growth/decay is given as:
In this problem:
The city's initial population is 120,000 and it decreases by 1.4% per year.
- Since the population decreases, it is a Decay Problem.
- Decay rate, r=1.4% =0.014
- Initial Amount =120,000
Therefore, the function is:
When t=10 years
Just mulitiply the original price and times it by 172 do the same thing for both.
Answer:
Step-by-step explanation:
a) Input = -9 ⇒ x = -9
y = x² + 3
Plugin x = (-9),
y = (-9)² + 3
= 81 + 3 {(-9)² = -9 * (-9) = 81}
y = 84 ---> Output
y = √x - 2
= √-9 - 2 { i² = -1}
y = 3i - 2 ------> Output
b) Output = 0
y = x² + 3
x² + 3 = 0
x² = -3
y = √x -2
0 = √x - 2
√x = 2
Take square,
Step-by-step explanation:
<em><u>Here</u></em><em><u>,</u></em>
| −34 |
= 34
<em><u>As</u></em><em><u>,</u></em>
| | are absolute symbols so it's denote only the neutral number such as, | - 1 | = 1
