Well what you have to see here is where the lowest our x gets to and that is -7. Next we would want to find the highest x value that the graph gets to which is 7. The domain would be (-7, 7).
D=vt, distance is equal to velocity times time.
4v+3(v+3)=149 perform indicated multiplication
4v+3v+9=149 combine like terms on left side
7v+9=149 subtract 9 from both sides
7v=140 divide both sides by 7
v=20
So the ship traveled at a speed of 20 mph when heading east.
Answers:
Center = (4, 7)
Radius = 7
===========================================================
Explanation:
The general template of any circle is
(x-h)^2 + (y-k)^2 = r^2
This general circle has these properties:
Based on the equation your teacher gave you, we see that
- h = 4
- k = 7
- r = 7, since 7^2 = 7*7 = 49
Therefore, this circle has center = (4,7) and radius = 7
Side note: The center's y coordinate and radius aren't always the same value.
You first need to isolate the y
4x+9y=-108
9y=-4x-108 (subtract 4x from both sides)
y=-4/9x-12 (divide both sides by 9)
Then, by using the y=mx+b form, we can tell that the y-intercept is -12 so A
