The pattern in this is
, where n is the previous number in the sequence and x is the number you multiplied a number by to get the previous number. You start with twelve times two, then increase the number you multiply by by one.
The next number in the sequence is
1440.
Answer:
CCCCCCCCCC
Step-by-step explanation:
Use FOIL (First, Outside, Inside, Last)
x(x) = x²
x(9) = 9x
-2(x) = -2x
-2(9) = -18
x² + 9x - 2x - 18
simplify by combining like terms
x² + 9x - 2x - 18
x² + 7x - 18
x² + 7x - 18 is your answer
hope this helps
Answer:
y=4x+9
Step-by-step explanation:
Slope-intercept form is y=mx+b where m is the slope, and b is the y-intercept. Given the numbers, for both, you can plug them in and get the equation y=4x+9.
