Answer:
see below
Step-by-step explanation:
Cedarville
Year 1
1200 * 8% = 96 people
At the end the population is 1296
Year 2
1296 * 7% =90.72
1296+90.72 =1386.72 people
Pinedale
1200*15%=180
1200+180 = 1380
Cedarville has more people at the end of 2 years by 6.72 people
Since the 37 is negative the parabola will open downward.
The coefficient on the outside of the ^2 tells you if it opens up or down. If it's positive it opens upward and if it's negative it opens downward.
For the parabola to open sideways it would be a form of x = y^2
The answer should be D
Step by Step: |2x-2| <(or equal to) 6
Add 2 on both sides should give you, |2x| < 8
Divide both sides by 2, giving you 4
Other way, is doing the same but -2
Do a proportion
8/100= x/70
Cross multiply and divide
70 x 8= 560
560 divided by 100= 5.6
Answer is 5.6
You also could have done .08 x 70 which is also 5.6
5x + 2(x + 1) ≤ 23
Distribute the 2.
5x + 2x + 2 ≤ 23
Combine like terms.
7x + 2 ≤ 23
Subtract 2 from both sides.
7x ≤ 21
Divide both sides by 7
x ≤ 3
