Answer:
Step-by-step explanation:
125,000×1.05⁷ ≈ 175,888
Answer:
B. x ≥ -3
Step-by-step explanation:
-4 x - 10 ≤ 2
add ten by both sides
-4x≤12
divide -4 by both sides
x ≤ -3
BUT because you divded you have to switch the sign so
x ≥ -3
Answer:8
Step-by-step explanation:
If we were to foil
after experieence
we know
ax²+bx+c=0
and
in form
(ax+b)(cx+d)=0
if we expand it, we get
acx²+bcx+adx+bd=0
or
(ac)x²+(bc+ad)x+(bd)=0
compare to
ax²+bx+c=0
we notice that the middle terms (x terms) are
b=(bc+ad)
so
in form
(2x-1)(1x+5)
b=bc+ad=(-1*1+2*5)=-1+10=9
b=9
or you could just expand it
