Just find the slope between the points
basically find (f(10)-f(7))/(10-7)
f(7)=7^2-3(7)-4=49-21-4=24
f(10)=10^2-3(10)-4=100-30-4=66
slope=(66-24)/(10-7)=42/3=14
average rate of change is 14
Answer:
Minimum percent of the vote that candidate Towne is expected to recieve:
m=51% - 6.3% * 51% =47.787%
Maximum percent of the vote that candidate Towne is expected to recieve:
M=51% + 6.3% * 51% = 54.213%
Solution:
Margin of error: E=6.3%
Minimum percent of the vote that candidate Towne is expected to recieve:
m=51% - E * 51%
m=51% - 6.3% * 51%
m=51% - 51% * 6.3 / 100
m=51% - 3.213%
m=47.787%
Maximum percent of the vote that candidate Towne is expected to recieve:
M=51% + E * 51%
M=51% + 6.3% * 51%
M=51% + 51% * 6.3 / 100
M=51% + 3.213%
M=54.213%
Answer:
Step-by-step explanation:
<h3>Given inequality</h3>
The LHS is absolute value so we look at two options:
<h3>Option 1</h3>
5x + 3 is positive, then the inequality becomes:
- 5x + 3 < 2
- 5x < 2 - 3
- 5x < - 1
- x < - 1/5 or x < - 0.2
<h3>Option 2</h3>
5x + 3 is negative, then the inequality becomes:
- - (5x + 3) < 2
- 5x + 3 > - 2
- 5x > - 2 - 3
- 5x > - 5
- x > - 1
The solution is the combination of the two intervals:
- x > - 1 and x < - 0.2 ⇒ - 1 < x < - 0.2
Correct choice is B
