Answer:
a-b = 31 (a ≠ b)
Step-by-step explanation:
(3x²-x+1)(px²+qx+1) = ax⁴+bx³+12x² - 6x + 1
3px⁴+(3q-p)x³+(3+p-q)x²+(q-1)x+1 = ax⁴+bx³+12x² - 6x + 1
q-1 = -6 q = -5
3+p-q = 3+p-(-5) = 8+p = 12 p = 4
b = 3q-p = 3*(-5) - 4 = <u>-19</u>
a = 3p = 3*4 = <u>12</u>
a-b = 12 - (-19) = 31

Answer:
7-y=-3(6-x)
Step-by-step explanation:
Point slope form:
Substitute y in for 7. Substitute x in for 6. Substitute m in for -3.
Answer:
y = x + 3
Step-by-step explanation:
y = mx + b
-4 = -7 * 1 + b
-4 = -7 + b
3 = b
y = x + 3
