Answer:
Step-by-step explanation:
Factor out a 6 from the numerator and 2 from the denominator
2 in the denominator divides the 6 in the numerator
factor the denominator, let me know if you need help with this
the (x+6)s cancel
X=14-2y
so, 14-2y+3y=9
y=1
x=14-2*1=12
Hope this answer can help you!
Answer:
y = 6x - 43
Step-by-step explanation:
(6, -7) and (8,5)
m=(y2-y1)/(x2-x1)
m=(5 + 7)/(8 - 6)
m= 12/2
m = 6
y - y1 = m(x - x1)
y + 7 = 6(x - 6)
y + 7 = 6x - 36
y = 6x - 43
25×(1−0.18)^(4)
=11.30
25*0.01=25(1-0.18)^t
0.25=25(0.82)^t
0.25/25=(0.82)^t
t=log(0.25/25)/log(0.82)
t=log(0.25÷25)÷log(0.82)
t=23.21 hours
