Answer:
15 is the answer
Step-by-step explanation:
20×4=80
80-65=15
Answer:
The approximate percentage is 25%.
Step-by-step explanation:
The initial population was = 12089 rounded off to 12000.
The final population is = 15025 rounded off to 15000.
Change in population = ![15000-12000=3000](https://tex.z-dn.net/?f=15000-12000%3D3000)
So, the approximate percent increase is =
![\frac{3000}{12000}\times100](https://tex.z-dn.net/?f=%5Cfrac%7B3000%7D%7B12000%7D%5Ctimes100)
= 25%.
Answer:
the answer is 11.7 because you round up the decimals
The slope-intercept form:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
m - slope
b - y-intercept → (0, b)
We have the points (-4, -6) and (2, 6). Substitute:
![m=\dfrac{6-(-6)}{2-(-4)}=\dfrac{12}{6}=2\\\\y=2x+b](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B6-%28-6%29%7D%7B2-%28-4%29%7D%3D%5Cdfrac%7B12%7D%7B6%7D%3D2%5C%5C%5C%5Cy%3D2x%2Bb)
Put the coordinates of the point (2, 6) to the equation of a line:
![6=2(2)+b\\\\6=4+b\qquad|-4\\\\2=b\to b=2](https://tex.z-dn.net/?f=6%3D2%282%29%2Bb%5C%5C%5C%5C6%3D4%2Bb%5Cqquad%7C-4%5C%5C%5C%5C2%3Db%5Cto%20b%3D2)
<h3>Answer: y = 2x + 2</h3>
