Answer:
The answer is c. 16x2 + 24xy + 9y2.
Step-by-step explanation:
Answer:
x=9
Step-by-step explanation:
- -54 + 6x = 6 • (x - 9)
- Solve : 6 = 0
- Solve : x-9 = 0
- Add 9 to both sides of the equation : x = 9
Answer:
D. 
Step-by-step explanation:
We graph the points on the graph. The graph is attached.
Let us take two points (1, 14) and (15, 1), and calculate the slope 
between them <em>(we choose these points because the line passing through them will be the best fit for all points) </em>
Thus we have the equation
Let us now calculate 
from the point 
So the equation we get is
Let us now turn to the choices given and see which choice is closest to our equation: we see that choice D. is the closest one, so we pick it.
Let Cameron be x years old now.
-
<u>Now:</u>
Cameron = x
Uncle =3x
-
<u>4 years ago:</u>
Cameron = x - 4
Uncle = 3x - 4
-
<u>4 years ago, Uncle is 4 times older:</u>
3x - 4 = 4(x - 4)
-
<u>Find x:</u>
3x - 4 = 4(x - 4)
3x - 4 = 4x - 16
4x - 3x = 16 - 4
x = 12
-
<u>Find the age:</u>
Cameron = x = 12
-
Answer: Cameron is 12 years old now.
Answer:
270 dollars for a year, so 22.50 times 12
