You need to find area or what?
Y=mx+b
m=slope
b=yintercept
given
slope=-1/4
yint=5
y=-1/4x+5
Answer:
1)
2)0
Step-by-step explanation:
for part 1:
Given cos(x) - cos^3(x)
= cos(x) (1- cos^2(x))
Using the identity 
= cos(x)sin^2(x)
for part 2:
given
=
Using the identity cos(a)cos(b) + sin(a)sin(b)= cos(a-b)
=
=
=
=0!
Answer:
1+5*2 or simplified, 1+10= 11
Answer:
n=-7/2 I hate asking for things but can i have brainliest im trying to rank up.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
n/7−12=5n+5
1/7n+−12=5n+5
1/7n−12=5n+5
Step 2: Subtract 5n from both sides.
1/7n−12−5n=5n+5−5n
-34/7n−12=5
Step 3: Add 12 to both sides.
-34/7n−12+12=5+12
-34/7n=17
Step 4: Multiply both sides by 7/(-34).
(7/-34)*(-34/7n)=(7/34)*(17)
