Answer:
59049 each term is the last multiplied by -3.
Answer:
y=2x+6
Step-by-step explanation:
You can first set up the equation in point slope form and plug in your two points to solve for slope
y-y=m(x-x)
8-2=m(1+2)
6=m(3)
m=2
Then plug in one point into the point slope form equation to make it into slope intercept form
y-8=2(x-1)
y=2x-2+8
y=2x+6
Answer:
3
Step-by-step explanation:
x = ± i
rearrange the equation and equate to zero
2x² - 6x = - 5 ⇒ 2x² - 6x + 5 = 0
this doesn't factor with integers, hence use the quadratic formula to solve
with a = 2, b = - 6 and c = 5
x = (6 ± √(36 - 40 ) )/4
= (6 ± √(-4) ) / 4
= (6 ± 2i ) / 4
x = ± i
