2x-4y=-16
ax+4y=6 +
--------------------
2x+ax=-10; for x=-2,
2(-2)+a(-2)=-10
-2a=-10+4
a=-6/-2
a=3
I=P(1+(r/n))^nt
I is the value owed
r is the rate in a decimal
n is the times compounded (annually =1, quarterly =4, monthly =12 etc.)
t is time invested
I=8000(1+(.109/1))^5x1
I=8000(1.109)^5
I=8000(<span>1.67748)

Answer:
For every 7 hair bands there will be 4 ribbons
7 hair bands →→ 4 ribbons
14 hair bands →→ 8 ribbons
21 hair bands →→ 12 ribbons
etc.
Speed is given by the formula:
speed=distance/ time
this implies that when we rewrite the above formula for distance we shall have:
distance=speed*time
from our question:
speed=60 mph
time=3 1/2 hours=3.5 hours
thus
distance=60x3.5
=210 miles
the answer is 210 miles
Answer:
x
Step-by-step explanation:
Using the trigonometric identities
1 + tan²x = sec²x and 1 - sin²x = cos²x
secx = 
Given
= 
= 
= cos²x × cos²x
= x
