Answer:
16b4=9
Step-by-step explanation:
(4b²+3) (4b²-3)
16b4-12b²+12b²-9
16b(raised to power 4)-9
16b4-9

16b4=9
Step-by-step explanation:
Divide two on both sides to get rid of it and the make the equation in the form y = mx + c

y = 3/2x + 5
since both lines are parallel they must have the same gradient which is 3/2
y = 3/2x + c
All you have to do now is to replace x and y with (2, -5) to find c
x = 2
y = -5
-5 = 3/2 × 2 + c
-5 = 3 + c
c = -5-3
c = -8
